Factors influencing nematicide root protection: Movement in root: Seed-applied nematicides do not move through the vascular system toward the growing point of the root system, so the amount that comes off individual seeds must come directly into contact with nematodes in soil to cause paralysis which impedes infection. Nematicides that bind to the seed coat are less likely to move into the soil water phase, limiting the “zone of protection” around roots. Movement in soil: Nematicides that have low water solubility are less likely to be distributed in the soil water phase than those with a moderate solubility. Nematicides that have limited movement in the soil water phase, due to low water-solubility, have a smaller “zone of protection” with less protection further from the seed. Nematode population density: Seed-applied nematicides are marketed for use at low nematode densities. When nematode densities are severe, this usually means there are more nematodes outside the zone of root protection, but still within the zone of root expansion. In this scenario, risk of infection remains high, as roots expand beyond the nematicide “zone of protection.” Read more at cropprotectionnetwork.org/pu… from @travisfaske @CUESNews & @MUExtension. @UFcropnematodes @UCDavisEntomolo @UFEntNem @LSUNematology @SON_nemaweb @ArkAgResearch @ARCrops @AR_Extension

It's essential to test grain for mycotoxins if corn ear rots are a significant problem. Obtaining a representative sample for mycotoxin testing is critical for accurate results.
