Nematode Management for Corn

Almost all types of soil contain phytoparasitic nematodes, which make up one of the largest animal phyla and can survive in a variety of global habitats. These nematodes eat plant roots, damaging and distorting the plants. Plants contract diseases and viruses from the saliva of nematodes, which not only destroy plants but also weakens them such as they are more susceptible to other diseases. Nematodes may also affect the marketability of plants by disfiguring them and giving them a lower resale value.

There are a number of plant parasitic nematode species on corn and under heavy pressure their feeding can result in a yield loss of 10-20% or more. Nematodes live below ground and can be hard to detect, but even low infestations can result in a loss of 1-10 bushels per acre. The damage threshold for some of the corn nematode pests, such as needle and sting nematodes, can be as low as 1 per 100 cm3 of soil. Most fields in the Midwest have corn nematodes and some species can feed and maintain their populations on soybean as well.

Compatible with other beneficial mycorrhizal fungi as well as other seed treatment products, Aveo™ EZ protects crops from nematode damage. Aveo EZ contains the bacteria, Bacillus amyloliquefaciens strain PTA 4838 that works to colonize plant roots, creating a bio-barrier that prevents nematode penetration of the roots. Aveo EZ can also cause juvenile nematode paralysis making the pest immobile and unable to damage the crop.
