  • Typical symptoms include severe galling (knotty root growths stimulated by nematode infection) of the root system, and above ground symptoms such as stunted growth, wilting, and leaf yellowing, which may resemble water and nutrient stress. (qld.gov.au)
  • Vine symptoms due to infection are similar to that of plant under water stress. (unl.edu)
  • We estimated the prevalence, intensity, and abundance of swimbladder nematode infection in 1281 lake whitefish ( Coregonus clupeaformis ) collected from four sites in northern lakes Huron (Cheboygan and DeTour Village) and Michigan (Big Bay de Noc and Naubinway) from fall 2003 through summer 2006. (bioone.org)
  • Total C. farionis prevalence was 26.94%, while the mean intensity and abundance of infection was 26.72 and 7.21 nematodes/fish, respectively. (bioone.org)
  • We found that nematode infection damages the endodermis leading to the activation of suberin biosynthesis genes at nematode infection sites. (bvsalud.org)
  • Eggs hatch into a juvenile nematode which looks similar to the adult nematode. (umn.edu)
  • This is critical because there are no longer any post-plant chemical control options for nematodes on grape, so control must be achieved before planting. (msu.edu)
  • The aim of this public-private partnership it to develop knowledge and instrument to sustainable improve soil quality in the flower bulb sector with a specific focus on the control of nematodes. (wur.nl)
  • The PPS flower bulbs, soil, nematodes: integrated approach develops a methods to improve soil quality and develops knowledge to develop control strategies for nematodes. (wur.nl)
  • Within this public-private partnership, we will study, the plant host status of nematodes, the control strategies of stem nematodes and Trichodorides, which is an increasing problem for flower bulbs. (wur.nl)
  • For further information on how this change might apply to you, see FAQs - potato cyst nematode control area and related permits . (vic.gov.au)
  • There are several other ways to control harmful nematode outbreaks. (gardenguides.com)
  • Nematodes are notoriously difficult to control, and the most effective management practices are preventative. (plantwise.org)
  • Chemical control using nematicides is not recommended for the control of nematodes as these chemicals are often expensive and highly toxic to both humans and the environment. (plantwise.org)
  • This month's Factsheet for Farmers highlights an existing method for the control of nematodes in banana plantations, using nematicidal plants. (plantwise.org)
  • As part of the curation process, taxonomic strings were standardized to contain a fixed number of taxonomic ranks relevant to nematology and updated for the most recent accepted nematode classifications. (unl.edu)
  • Macroposthonia ornata, Tylenchorhynchus annulatus, and Pratylenchus species were the most frequently associated nematodes. (icrisat.org)
  • Nematodes require a moisture retentive soil, enabling them to 'swim' between soil aggregates and are, in the main, more severe where root development is restricted. (pitchcare.com)
