Nematode Management for Cereal Grains

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 that feed on cereal grains. The most important are various species of root knot nematode, but lesion, and cereal cyst nematodes can also be significant pests. Infestations can be hard to detect, but high nematode populations and heavy feeding can result in plants that can be chlorotic, stunted in growth, with reduced tillering and inhibition of grain head formation.  Heavy infestations of nematodes are reported to reduce yields by 30% or more.

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.
