chemical used in genetically engineered (GE) fields. Dicamba, a toxic pesticide prone to drift off the target site, has been used in agriculture for decades. However, new GE crops developed by Monsanto must be paired with specific formulations of dicamba, and until now many believed these drift incidents were the result of illegal formulations of dicamba being applied to fields. But the extent of damage now being observed, covering over 2.5 million acres, is casting doubt on this theory, and raising more questions as to whether the new dicamba formulation is actually the cause of the widespread drift damage.. Fruits and vegetables, as well as other crops that are not genetically engineered to tolerate dicamba are often left cupped and distorted when exposed to the chemical. Monsanto, DuPont Co. and BASF SE sell new formulations of the herbicide for use on dicamba-tolerant soybeans and cotton, and state enforcement officials and farmers have attributed last years damage incidents to off-label ...
Dicamba has caused a lot of controversy in the past. In August 2016, farmers in Missouri, Arkansas, and Tennessee confronted widespread crop damage and braced for lower yields as a result of agrichemical giant Monsantos botched roll-out of GE soybean and cotton crops. The company, whose current line of glyphosate-tolerant crops are failing to control weeds throughout the U.S. and across the globe, developed a new line of soybean and cotton with traits that make it tolerate applications of dicamba. After numerous complaints, EPA launched a criminal investigation at several locations in Missouri into the illegal spraying of dicamba in October 2016. Many suspect that farmers who planted the new dicamba-tolerant genetically engineered (GE) seeds in the region, when faced with a proliferation of pigweed, illegally sprayed dicamba across their fields, leading to drift and off-site crop damage to other farmers. Monsanto is currently embroiled in a legal battle with a farmer who projected that he would ...
More than 2,000 reports of dicamba damage are now under investigation; an estimated 3.1 million acres has been damaged by dicamba drift this season.
Farmers had to use third-party older dicamba-based herbicides with Monsantos seeds, despite the companys warnings. According to multiple reports, such activities caused a massive damage to off-target non-GM crops in at least ten states in America.. The affected crops included soybeans, tomatoes, cantaloupes, watermelons, rice, cotton, peas, peanuts, alfalfa and even peaches. Bill Bader, owner of Bader Peaches, Missouris largest peach producer, estimated a loss of 30,000 trees.. "We need to go after Monsanto. These farmers are being hung out to dry," said Bader.. Arguments over dicamba drifts between farmers even led to a shooting in Arizona, which left one farmer dead, according to local law enforcement.. Even with the approval of the brand new herbicide, some farmers affected by the drifts, said they would have to switch to Monsantos dicamba-resistant crops to protect themselves from possible incidents in the future, by way of insurance, St. Louis Dispatch reported. EPA launched a criminal ...
As farmers face mounting pressure from resistant pigweed, some are turning to off-label use of an herbicide, causing damage to thousands of acres of crops, according to complaints fielded by regulators in Arkansas and Missouri. At issue is dicamba, an herbicide that offers some control of resistant pigweed. If and when the Environmental Protection Agency approves, dicamba is intended for use on Xtend cotton and soybeans. Xtend cotton and soybeans were developed by Monsanto to resist dicamba. Its been planted for the first time on a limited number of acres in Arkansas. Tom Barber, extension weed scientist for the Division of Agriculture, said reports of injury were concentrated in northeast Arkansas, although he had received word of similar incidents in Lee, Lonoke and Phillips counties as well. "What appears to be happening is that growers planted this technology, then decided to make off-label applications of dicamba over the top for weed control prior to the product receiving a full herbicide ...
The development of crops resistant to 2,4-D, dicamba, and glufosinate may provide new options for the management of glyphosate-resistant (GR) giant ragweed and other herbicide-resistant weeds. A fallow field study was conducted in 2011 and 2012 to determine the control of GR giant ragweed with 2,4-D and dicamba applied alone and in combination with glufosinate or fomesafen. Dicamba and 2,4-D tank-mixed with glufosinate or fomesafen provided the highest level of control at 10 or 20 days after application (DAA). At 30 DAA, all herbicide treatments provided ,88% control of giant ragweed except glyphosate, glufosinate, and 2,4-D alone at 0.56 kg ae ha-1. Glyphosate, glufosinate, and 2,4-D alone at 0.56 kg ae ha-1 also had the highest number of giant ragweed plants (,5.8 plants m-2) and highest biomass (,19.2 g m-2). Contrast statements between 2,4-D and dicamba indicated no differences among treatments containing these herbicides. However, contrast analysis indicated that herbicides applied alone ...
Laboratory experiment was carried out on light dusty clay, into which two herbicides: Izoturon 500 SC (composed of isoproturon only) and Rokituron D 470 SC (composed apart from isoproturon of 2,4-D and dicamba), were introduced in the following doses: recommended field dose (FD), tenfold higher dose (10FD) and one hundredfold higher dose (100FD). The amount of isoproturon introduced together with Izoturon 500 SC and Rokituron D 470 SC was the same, which allowed for assessing the effect of 2,4-D and dicamba on the rate of isoproturon decay in soil as well as for evaluating the modification of changes in soil biochemical parameters induced by isoproturon introduction into it by 2,4-D and dicamba. During the experiment, the content of isoproturon and its metabolites: MDIPU, DDIPU and 4-IA, and of dicamba and 2,4-D in soil as well as the activity of catalase, dehydrogenase and nitrate reductase. Isoproturon DT50 in soil ranged between 9.7 and 18.5 days and rose together with a dose increase. MDIPU, ...
Bayer AG and alleged co-conspirator BASF are appealing a $265 million jury verdict in favor of a Missouri peach farmer who claimed dicamba herbicide formulations produced by the companies irreparably damaged his peach orchard.
The stacked soybean line MON-877Ø5-6 x MON-877Ø8-9 x MON-89788-1 was obtained through the traditional cross breading of each of the parental organisms to produce an organism that expresses each of Dicamba monooxygenase, EPSPS and results in the antisense suppression of the FATB and FAD2 genes. This results in dicamba and glyphosate herbicide tolerance and a modified fatty acid profile ...
The injury data in Table 1 were collected from a study conducted in 2007 in southwest Nebraska at sites near McCook and North Platte at UNLs West Central REC Dryland Research Farm. Herbicide treatments were applied to Jagalene winter wheat in combination with 28-0-0 (urea ammonium nitrate). Injury such as this, and even greater, is common when combining fertilizer and herbicide treatments. Injury tends to increase as fertilizer and /or herbicide rates increase. Herbicide products containing dicamba tend to produce slightly more crop injury. Dicamba also can cause the wheat plant to assume a "sleepy" appearance, with the leaf blades held less erect. (Note that in both locations all plots, including untreated plots, include injury from an extended period where temperatures dropped below freezing and snowfall occurred.) The injury usually disappears or is hidden by new wheat growth as the crop continues growing (Figure 1).. While injury symptoms are fairly common, the effect on grain yields is ...

By Nick Meyer On August 14, 2017 The Monsanto Company has often said that its work is done with the best interests of the farmer in mind, but as many have discovered, there are plenty of examples where the results end up having the complete opposite effect, to say the very least. Recently, a spate of incidents linked to one controversial Monsanto. ...

Maize is one of the most important cereal crops in Sub-Saharan Africa and an important source of energy for humans. However, the difference in the dedifferentiation frequency of immature embryos among various genotypes indicates that callus induction and genetic transformation is dependent on the genotype. This phenomenon is an impediment in the fundamental process of improving tropical maize germplasm especially through genetic engineering. Here, five tropicalmaize (Zea maysL.) genotypes were tested for callus induction and subsequent regeneration on MS medium supplemented with a growth regulator dicamba. Genotype-independent embryogenic calli were inducedfrom immature zygotic embryos, 12 days after pollination, of maize inbred lines, CML216, CML144,A04, E04 and TL21 on MS medium supplemented with different levels (1 to 5 mg/L) of plant growth regulator dicamba. The optimal concentration of dicambafor induction of embryogenic callus in all the genotypes was 3 mg/L, which was also the ...
In a project that began about a dozen years ago, University of Nebraska-Lincoln scientists discovered a gene that has been used to create broadleaf crops that tolerate spraying with the popular herbicide dicamba. Now, even as an industry partner is working to bring dicamba-resistant crops to market, these plant scientists are continuing to explore new and expanded uses for the technology they discovered.
Item 1. New research finds common herbicides cause antibiotic resistance. New University of Canterbury research confirms that the active ingredients of the commonly used herbicides, RoundUp, Kamba and 2,4-D (glyphosate, dicamba and 2,4-D, respectively), each alone cause antibiotic resistance at concentrations well below label application rates.. UC Molecular Biology and Genetics academic, Professor Jack Heinemann, of the School of Biological Sciences, in UCs College of Science, says the key finding of the research was that "bacteria respond to exposure to the herbicides by changing how susceptible they are to antibiotics used in human and animal medicine.". The herbicides studied are three of the most widely used in the world, including New Zealand, Professor Heinemann says.. "They are among the most common manufactured chemical products to which people, pets and livestock in both rural and urban environments are exposed. These products are sold in the local hardware store and may be used ...

A recent study from University of Canterbury in New Zealand shows that glyphosate (Roundup) and other commonly used herbicides can make bacteria quickly adapt and resist antibiotics like ampicillin and tetracycline. Glyphosate, 2,4-D (dioxin) and dicamba (recently approved by the FDA) appear to disable the antibiotics and trigger bacterial resistance to them. Researchers tested E.…

The scientists decided to see if these herbicides had the same harmful late-stage application effects on the invasive weed Japanese brome. In greenhouse experiments, they tested dicamba (Banvel/Clarity), 2,4-D, and picloram (Tordon) at typically used rates. They found that picloram reduced seed production nearly 100 percent when applied at the late growth stage of the weed. Dicamba was slightly less effective, but still nearly eliminated all seed production, while 2,4-D was much less effective.. Since annual grass seeds only survive in soil a year or two, it should only take one to three years of herbicide treatment at the right growth stage to greatly reduce the soil seed bank of annual weedy grasses without harming perennial grasses.. Rinella has recently finished field tests that support the greenhouse experiment results. He also tested the herbicide aminopyralid (Milestone) and found it was as effective as picloram. Next he will test much lower doses of the herbicides in an attempt to lower ...

Politico , Posted on February 20, 2018 An Arkansas judge on Friday dismissed a lawsuit filed by Monsanto seeking to block the states plan to ban the warm-weather use of the herbicide dicamba. Monsanto and the Arkansas Plant Board have been engaged in a monthslong fight over the use of the herbicide in the state. The plant board - which is made up of farmers, agricultural business representatives, pesticide officials and weed scientists - voted last year to prohibit the use of the herbicide from April 16 through Oct. 31 after widespread complaints from farmers that the herbicide drifted from neighboring fields and damaged their crops.In response, Monsanto not only sued the board, but also sued the boards 13 members individually. Arkansas lawmakers, however, upheld the plant boards decision in January.The Pulaski County Circuit Court judge threw out the case based on an Arkansas Supreme Court ruling that makes it difficult to sue state agencies."We are disappointed in the courts decision to ...
By S. D. Wells. As reported on Natural News by David Gutierrez in October of 2014: "A field of unregulated genetically modified (GM) wheat has been discovered growing wild in Montana, the U.S. Department of Agriculture (USDA) has announced. No varieties of GM wheat have been approved for cultivation in the United States, but this is the second plot discovered growing on its own in less than a year and a half.". Do you think those two plots of genetically modified wheat are the only two out there? When wheat carries the traits of "herbicide resistance," that means more and more herbicide will have to be sprayed as the weeds become resistant too. Agrochemical giant Monsanto is at it again, developing GM herbicide-resistant wheat. This time around, the wheat will be resistant to THREE different chemical herbicides: glyphosate, glufosinate and dicamba. Back in 2013, an Oregon farmer found Monsantos original "Roundup Ready" wheat growing in his fields. Monsanto had claimed to stop developing that ...
Glyphosate, an herbicide and the active ingredient in Monsanto Cos popular Roundup weed killer, will be added to Californias list of chemicals known to cause cancer effective July 7, the states Office of Environmental Health Hazard Assessment (OEHHA) said on Monday.. Monsanto vowed to continue its legal fight against the designation, required under a state law known as Proposition 65, and called the decision "unwarranted on the basis of science and the law.". The listing is the latest legal setback for the seeds and chemicals company, which has faced increasing litigation over glyphosate since the World Health Organizations International Agency for Research on Cancer said that it is "probably carcinogenic" in a controversial ruling in 2015.. Dicamba, a weed killer designed for use with Monsantos next generation of biotech crops, is under scrutiny in Arkansas after the states plant board voted last week to ban the chemical.. OEHHA said the designation of glyphosate under Proposition 65 will ...
This time last year, we were suffering from a herbicide problem which stunted our Roma paste tomatoes. No, we didnt spray herbicide on them. Someone else sprayed Triclopyr growth regulator herbicide (Ortho Poison Ivy Killer) on poison ivy down the road, behind some trees. He sprayed on 5/23, and made repeat sprays twice, about two weeks apart (approx. June 4th and 18th). As the crow flies, it might be 600 ft or so from the tomatoes.. Some other brand names of Triclopyr include Grandstand, Alligare, Garlon and Horsepower. Other growth regulator herbicides include 2,4-D, Aminopyralid, Dicamba, Diflufenzopyr, Picloram, Quinclorac, as well as Triclopyr.. On June 18 2016, we noticed some of the younger leaves on our plants were curling inwards and buckling an odd way. There were no obvious spots or mottling, but the sick plants were stunted. Most of the damaged plants were in groups in low areas.. I thought it was a virus. We decided not to handle the plants until we had a diagnosis, for fear of ...
column][/column-group]. Because Monsanto told the EPA that glyphosate is the only active ingredient in Roundup, the EPA ignores all the other chemicals in the herbicide mixture and only reviews data on glyphosate[12]. But other chemicals found in Roundup are themselves endocrine disruptors and can be as much as 1,000 times more toxic than glyphosate[13].. EPA serving corporate interests. Why has the EPA ignored serious, life-threatening properties of the worlds most widely used herbicide? A letter by the unions representing EPA workers may give us a clue. They cited "political pressure exerted by Agency officials perceived to be too closely aligned with the pesticide industry and former EPA officials now representing the pesticide and agricultural community[14].". Those former EPA officials might include William D. Ruckelshaus, the EPA chief administrator who later became a member of Monsantos board of directors[15]; or Linda J. Fisher[16], who was Monsantos Vice President of Government and ...
The discovery of auxinic herbicides (e.g., 2,4-D, Dicamba, Picloram) for selective control of broad-leaf weeds in cereal crops revolutionized modern agriculture. These herbicides are inexpensive and do not generally have prolonged residual activity in soil. Although cultivated species of Brassicaceae (e.g., radish and other vegetables) are susceptible to auxinic herbicides, some biotypes of wild mustard (Sinapis arvensis, 2n=18) were found to be highly resistant to Picloram and Dicamba. Inter-generic hybrids between wild mustard and radish (Raphanus sativus, 2n=18) were produced by traditional breeding coupled with in vitro embryo rescue/ovule culture. To increase frequency of embryo regeneration and hybrid plant production, several hundred reciprocal crosses were performed between these species. Upon altering cultural conditions and media composition, a high frequency of embryo regeneration and hybrid plant establishment was achieved. A protocol was also optimized for in vitro clonal ...
Typically the best time to apply a fall burndown is from mid-October through mid-November. Herbicides can be applied after this time, but weeds are less susceptible to herbicides after a hard freeze. A typical burndown mix in the fall is a combination of glyphosate with 2, 4-D and/or Dicamba. This will allow control of emerged weeds early and put less pressure on spring burndown applications and make them more effective. A debated topic is whether to include a residual herbicide in the mix. A lot of this decision is dependent on the weather. A residual in the fall can keep a field clean until planting season, but in the event of a harsh cold winter, a residual can last too long and injure the next crop. Also in the event of a mild winter, the residual can break down quickly and allow winter annuals to emerge early spring. For these reasons, it is typically recommended to not outguess Mother Nature and to save your money on residual herbicides for in-season. Weed control is by far the most ...
Herbicides are frequently released into both rural and urban environments. Commercial herbicide formulations induce adaptive changes in the way bacteria respond to antibiotics. Salmonella enterica sv. Typhimurium and Escherichia coli were exposed to common co-formulants of formulations, and S. enterica sv. Typhimurium was exposed to active ingredients dicamba, 2,4-D and glyphosate to determine what ingredients of the commercial formulations caused this effect. Co-formulants Tween80 and carboxymethyl cellulose induced changes in response, but the pattern of the responses differed from the active ingredients, and effect sizes were smaller. A commercial wetting agent did not affect antibiotic responses. Active ingredients induced changes in antibiotic responses similar to those caused by complete formulations. This occurred at or below recommended application concentrations. Targeted deletion of efflux pump genes largely neutralized the adaptive response in the cases of increased survival in antibiotics,
Pesticides can be present in the atmosphere either as vapours and/or in association with suspended particles. High-volume air sampling, in which air is aspirated first through a glass fibre filter to capture pesticides associated with atmospheric particulates and then polyurethane foam (PUF), often in combination with an adsorbent resin such as XAD-2, to capture pesticides present as vapours, is generally employed during atmospheric monitoring for pesticides. However, the particulate fraction may be underestimated because some pesticides may be stripped or desorbed from captured particulates due to the pressure drop created by the high flow of air through the filter. This possibility was investigated with ten herbicide active ingredients commonly used on the Canadian prairies (dimethylamine salts of 2,4-D, MCPA and dicamba, 2,4-D 2-ethylhexyl ester, bromoxynil octanoate, diclofop methyl ester, fenoxaprop ethyl ester, trifluralin, triallate and ethalfluralin) and seven hydrolysis products (2,4-D, MCPA,

Creatinine is a metabolic waste product, removed from the blood by the kidneys, and excreted in the urine. The measurement of creatinine is used in the assessment and monitoring of many medical conditions as well as in the determination or adjustment of absorbed dosage of pesticides. Earlier models to predict 24-hour urinary creatinine used ordinary least squares regression and assumed that the subjects observations were uncorrelated. However, many of these studies had repeated creatinine measurements for each of their subjects. Repeated measures on the same subject frequently are correlated. Using data from the NIOSH-CDC Pesticide Dose Monitoring in Turf Applicators study, this thesis project built a model to predict 24-hour urinary creatinine using the Mixed Model methodology. A covariance structure, that permitted multiple observations for any one individual to be correlated, was identified and utilized. The predictive capabilities of this model were then compared to the earlier models
In view of the shallow and superficial roots of cocoa, control of weeds by herbicides in cocoa is preferable to hand weeding with changkol or sickle. However, especially when the plants are small, serious damage may be caused by herbicide drift.. Commencement of use of herbicide spraying in cocoa should therefore be when the plants are large enough and with some brown bark and with sufficient leaves not to be significantly damaged by herbicide if some leaf scorch should happen. The sprayers should also be skilled and careful.. Herbicides have different effects on cocoa (Brown and Boeting, 1972; Tan et al. 1972) and many are less safe to use in view of very serious damage which my be caused, in particular, by the translocated herbicides eg. the phenoxyacetic acids (2, 4-D and 2,4,5-T) and the halogenated aliphatic acids (dalapon, TCA) on accidental damage.. The literature eg. Wood (1975) cites several suitable herbicide mixtures for cocoa containing the above translocated herbicides and including ...
phdthesis{3006170, abstract = {Plants as sessile organisms evolved a specific body structure and at the cellular level mechanisms that allow to survive under extreme environmental conditions. The body shape and subcellular processes are largely dependent on coordinated activity of a small molecule indole-3-acetic acid (IAA), auxin. Local gradients of IAA correlate spatiotemporally with such developmental events like embryogenesis, phyllotaxis, organ initiation or tropisms. Auxin maxima and minima are mostly mediated by auxin efflux carriers PINs. Asymmetric distribution of these proteins determines the directional flow and facilitates the auxin gradient formation. Aberrations in apical or basal auxin-carriers localisation leads to severe developmental defects. Therefore, it is crucial to understand the mechanisms initiating and controlling polar proteins localisation. Next to polarly distributed PINs, there is a growing group of polarly localized proteins transporting hormones or nutrients ...

Orach (Atriplex hortensis L.) is a halophyte plant, cultivated ever since the ancient times, used in the food industry, biotherapy, human medicine and apiculture. But, then it has a germinal capacity of about 25% and a duration of two years. These characteristics make the A. hortensis L. a plant with economic potential exploitable via biotechnological methods. These methods use phytoregulators as biochemical instruments capable of modeling somatic type explants cultivated in vitro for the purposes of the induction, generation and materialization of the properties characteristic of stem type cells. These properties are especially relevant by the use of auxinic or cytokininic type phytoregulators. The experimental researches described in this study has aimed at testing treatments with exogenous auxins or exogenous cytokinins of A. hortensis L., on somatic type explants cultivated in vitro, for the purposes of the induction, generation and materialization of properties characteristic of stem type ...

The goal of La Plata County Weed Management Program is to manage and/or eradicate noxious weeds in our region. We do this by controlling the weeds on County Roads and County Properties, and also through educating and helping landowners with vegetation on their property.. Large infestations can be stopped, reduced, managed and sometimes eventually eradicated. Smaller invasions can most times be fully eradicated before they have a chance to become established, and then spread throughout a sub region in the County. By accomplishing this landowners and managers help stop noxious weeds from forcing out native plants and animals from their natural environment.. La Plata County has an aggressive program when it comes to weed management. We have developed our own methods for tracking and controlling weeds and have worked with many landowners to help manage weeds on private properties. Below are some of the methods that have helped to control weeds thus far in La Plata County.. ...

Site of action refers to the biochemical site within the plant with which the herbicide directly interacts. Some herbicide site of action interactions are well understood, others are unknown. Many of the well-known sites of action are enzymes or proteins essential to plant growth and development (Figure 1 and Figure 2). Also, some herbicides are believed to act at multiple sites.. Metabolism refers to the biochemical processes within the plant that generally modify herbicides to less toxic compounds. Differential rates of metabolism between crops and weeds is a primary method of crop selectivity to herbicides. One metabolic process may affect several different families of herbicides.. Herbicide families are a convenient way of organizing herbicides that share a common chemical structure and have similar herbicidal activity. Two or more herbicide families may affect the same site of action and therefore express similar herbicidal activity and injury symptoms. A biotype is a group of plants within ...
Management of problematic aquatic weeds in Africa. The control of aquatic weeds in Africa is difficult and all sound options should be considered. When necessary, a combination of control measures may be used, depending on the nature of the local problem. Among the ways to control exotic weeds, environmentally friendly and sustainable methods should be adopted. A sound option is the so-called classical biological control, which is the use of beneficial organisms - the natural enemies that effectively limit the populations of the host plant in its area of origin - to reduce the growth and population density of the weed in the area of introduction. The organisms used are host-specific and do not harm other desirable plants. ...

INTRODUCTION. Vegetable growing imposes a particular weed-management approach. Vegetable areas are usually small, but produce high-value crops that are commercially and gastronomically appreciated. Fruit and leaf crops provide important income for farmers and workers at local or regional levels. Providing evidence of small surfaces used for growing vegetables, in Spain for the year 1999 the area covered 395 300 ha, with a production of about 12 million tonnes.. Irrigation is another typical characteristic of these crops in Mediterranean or arid areas. The type of irrigation used also conditions weed management because of the many systems available: traditional irrigation through flooding or by furrows, and the more modern sprinkling, drip and infiltration irrigation. Herbicides have different behaviour. Their incorporation is affected by water and crop selectivity can thus be substantially reduced.. Traditional vegetable-growing areas are usually situated adjacent to waterways, flood plains, ...
