Sorghum3
Co-expression network analysis revealed that aphid infestation modulates sorghum defenses by regulating genes corresponding to phenylpropanoid metabolic pathways, secondary metabolic process, oxidoreductase activity, phytohormones, sugar metabolism and cell wall-related genes. (biomedcentral.com)
This study offers further insights to better understand sorghum defenses against aphid herbivory. (biomedcentral.com)
Host plant resistance has proven to be highly economical and eco-friendly long term insect management strategy [ 8 ] that has been broadly used for the management of other sorghum pests such as greenbugs ( Schizaphis graminum ) and corn leaf aphids ( Rhopalosiphum maidis ) [ 9 , 10 ].

Entomopathogenic fungus2
Use of entomopathogenic fungi for controlling the aphids is well attempted and further substantiation of interaction of entomopathogenic fungus in cowpea plants against aphid were studied in detail. (indianentomology.org)
nicotianae and the aphid parasitoid Aphidius ervi as the experimental model, we explored whether root inoculation with an entomopathogenic fungus is compatible with parasitoid wasps for enhanced biocontrol of aphids. (rothamsted.ac.uk)
Populations1
Small aphid populations may be relatively harmless, but heavily infested plants usually have wrinkled leaves, stunted growth and deformed capsules. (infonet-biovision.org)
Corn5
Hot, dry weather at the start of wheat harvest signals spider mite infestations to move into soybeans, dry beans and possibly even the corn crop. (cropwalker.ca)

Illinois corn and soybean crops faring well. (geometry.net)
Nearly every farm in Ohio has a field or two that could benefit from planting wheat, if for no other reason than to help reduce problems associated with continuous planting of soybeans and corn. (osu.edu)
Diseases1
Planting within the first 10 days after this date insures the proper planting time to avoid serious insect and disease problems including Hessian Fly, aphids carrying Barley Yellow Dwarf Virus, and several foliar diseases. (osu.edu)
Insecticide1
Producers can reduce the chance of early infestations by using treated seed, an in-furrow liquid insecticide contacting the seed through an orifice spray or seed firmer, or the in-furrow granular insecticide aldicarb. (ncsu.edu)
Pest3
Aphids are a major pest, causing leaves to curl and attacked capsules become unattractive to customers. (infonet-biovision.org)
Catherine joined Dudutech as a Field Trials Officer in 2001 after graduating from University of Nairobi with an BSc in Agriculture, although her first experience with biologicals came from ICRISAT (International Crops Research Institute for the Semi-Arid Tropics) where she worked with natural enemies for pest control. (dudutech.com)
Rotating crops in diverse and complex patterns is one of the oldest agronomic approaches used by farmers to control nutrient and water balances, weed, pest and disease infestations and risk exposure, and to improve system resilience as well as to fulfill human and livestock food and feed needs 11,12 .

Wheat2
A sequential rationality test of USDA preliminary price estimates for selected program crops: rice, soybeans, and wheat. (geometry.net)
No-till wheat into soybean stubble is ideal, but make sure the soybean residue is uniformly spread over the surface of the ground. (osu.edu)
Leaf2
Aphids also secrete sugary substance known as honeydew, which allows the growth of sooty mold and results in reduced leaf area for light absorption and photosynthesis in plants, thus declining the photosynthetic efficiency of infested plants. (biomedcentral.com)
Growers are strongly advised to continue monitoring soybean fields that remain green and succulent throughout September for the presence of bean leaf beetles. (osu.edu)
Resistance1
There were 187 genes that were highly expressed during the early time of aphid infestation in the SCA-resistant line, including genes encoding leucine-rich repeat (LRR) proteins, ethylene response factors, cell wall-related, pathogenesis-related proteins, and disease resistance-responsive dirigent-like proteins. (biomedcentral.com)
Crop3
Soybean rust in state, Mississippi crop still OK. (geometry.net)
Under these conditions, inoculation is recommended for each soybean crop. (geometry.net)
Resistant3
Aphid feeding on the SCA-resistant line upregulated the expression of 3827 and 2076 genes at early and late time points, respectively, which was relatively higher compared to RTx430 and SC1345 plants. (biomedcentral.com)
At 7 days post infestation (dpi), 173 genes had elevated expression levels in the SCA-resistant line and were involved in sucrose metabolism, callose formation, phospholipid metabolism, and proteinase inhibitors. (biomedcentral.com)
In summary, our results indicate that the SCA-resistant line is better adapted to activate early defense signaling mechanisms in response to SCA infestation because of the rapid activation of the defense mechanisms by regulating genes involved in monolignol biosynthesis pathway, oxidoreductase activity, biosynthesis of phytohormones, and cell wall composition.

Parasitoid1
Inoculation of plants with A. muscarius did not affect parasitism rate nor parasitoid longevity, but significantly increased the speed of mummy formation in parasitized aphids on fungus-inoculated plants. (rothamsted.ac.uk)
Vegetables1
In Kenya, foliar sprays with neem products such as Neemroc(R) (1-3%) and Neemros(R) water extract (50g/l) controlled the black bean aphid on vegetables (Maundu, 1997). (infonet-biovision.org)
Adult1
Adult beetles that emerge from yellowing soybean fields will move to those that are still green to continue feeding prior to overwintering. (osu.edu)
Defense1
The foliar application of its crude formulation @ 108 spores ml-1 had significant influence on the induction of defense related enzymes and components against A. craccivora infestation in cowpea. (indianentomology.org)
Grown2
Also excluded are seeds that are mainly grown for oil extraction (oilseeds like soybeans and peanuts), and seeds which are used exclusively for sowing forage (clovers, alfalfa). (wikipedia.org)
This concern is especially important with food grade soybeans and those being grown for seed, both situations where seed quality is an issue. (osu.edu)
We used RNA-sequencing approach to identify the global transcriptomic responses to aphid infestation on RTx430, SC265, and SC1345 plants at early time points 6, 24, and 48 h post infestation (hpi) and after extended period of SCA feeding for 7 days. (biomedcentral.com)

Fields3
Cutworm infestation is often associated with fields that are weedy, have high amounts of organic residue or are very wet due to poor drainage or heavily irrigated. (infonet-biovision.org)
Infestations tend to start on the field edge's but with enough windy days, they can get carried deeper into fields. (cropwalker.ca)
Finally, smaller fields with more "edge" than "interior" are more at risk for infestation than larger fields. (ncsu.edu)
In one story Catherine told in an interview, she recalled isolating a natural enemy for aphids from her mother's garden. (dudutech.com)
