Thanks to the Arkansas Soybean Promotion Board and Dr. Travis Faske, who is cooperating with us, the Arkansas Nematode Diagnostic Lab will waive the assay fee for soybean fields for the 2018 season.
As in years past, we will be accepting soil samples for nematode assay from:
- Fields that are currently in soybean,
- Fields that will be in soybean next year,
- Fields that may be in longer term cropping systems that included soybean within the last 2-3 years, and
- cover crops that are in rotation with soybeans.
Please indicate the specific crop on the form. This is a continuation of our on-going soybean nematode survey of the state and will contribute significantly to our understanding of which nematodes are found in soybeans and where they are the most critical The assay fees for survey samples will be provided through a grant from the Arkansas Soybean Promotion Board.
Just for informational purposes, we have already received a number of soybean nematode samples for the 2018 season. So far, root-knot has been detected in 63% of the samples and soybean cyst nematodes were present in 21% of the samples. It might be a real good year to do some sampling!
If you or your grower (or consultant) have not already done so, we recommend that you take the on-line course, Collecting & Packaging Nematode Soil Samples (http://courses.uaex.edu/). This course will teach you how to take and handle soil samples for nematode assay and how to submit samples on-line through our DDDI program.
Remember that even apparently healthy fields may have nematodes that are not yet at an economic level. Here are the details for the survey:
- We will accept samples directly from county agents, consultants/crop advisors, or growers.
- There is no limit on the number of free samples that any county or individual can redeem.
- All samples need to be entered through our DDDI on-line sample submission program.
- In addition to the course listed above, details for sampling and handling samples can be found here.
