Summary

​Many fungicide seed treatments are available to control the seedling disease pathogen Rhizoctonia solani, and one chemistry is available to control Pythium spp. Fields that have root-knot or reniform nematodes often will have improved stands if both fungicide and nematicide seed treatments are utilized. At least seven different nematicide seed treatments are currently available. Nematicide seed treatments work best when there is plentiful rainfall or irrigation during the first several weeks after planting, since the chemicals are distributed passively around roots in the water.​

About the Presenter

Terry WheelerTerry Wheeler graduated with an MS from Texas A&M University ​​in plant pathology and then a PhD from North Carolina State University in plant pathology.​ Both degrees were obtained with a specialization in plant nematology; work was conducted with root-knot nematode species on tobacco and peanut. Dr. Wheeler then worked as a research associate at the Ohio Agricultural Research and Extension Center in Wooster on potato early dying (a disease complex involving Verticillium wilt and lesion nematode) and then at Ohio State University on the soybean cyst nematode. In 1994, Dr. Wheeler moved to Lubbock, Texas, to work on cotton and peanut diseases in the southern High Plains of Texas for the Texas Agricultural Experiment Station (later renamed Texas A&M AgriLife Research). Nematodes are one of the most important and consistent issues facing cotton production in this region, and Dr. Wheeler has worked extensively in nematode management (chemical, germplasm, and crop rotation) with both the root-knot and the reniform nematodes.​​
