Optimal time for sampling corn nematode is between V5 to V7 growth stage

There are many disease organisms that can reduce corn yields in Kansas. One of the stealthiest is the root-lesion nematode (RLN) because it operates below ground on the roots and often has no specific, identifiable symptoms other than yield loss. It is present, at some level, in nearly all corn fields in the state. Historically the largest yield losses, which can exceed 40 percent in individual fields, occur in western Kansas where irrigated, no-till, continuous corn production systems in sandy soils are common. Learn more about when and how to inspect RLN in your corn field.

After harvest is the optimal time for Soybean Cyst Nematode sampling

Soybean cyst nematode (SCN) is a major problem in soybean fields throughout eastern and central Kansas. It is important to monitor SCN levels regularly to determine if management strategies, such as variety resistance and crop rotation, have been successful. Free SCN testing is available through the KSU Plant Disease Diagnostic Lab. Find out more in this article.
