Efficacy of Phytogen Seed Treatment Products and Cultivars to Manage the Reniform Nematode in Mississippi

The reniform nematode, Rotylenchulus reniformis, can be a severe yield reducer in situations where the soilborne populations are greater than the economic threshold.  Effects of this pest are observed throughout the cotton growing areas of the southern United States.  Field trials were established during 2018-2020 at the Delta Research and Extension Center in Stoneville, MS.  The specific objectives of these trials were to determine the benefits of variety and seed treatment combinations in managing the reniform nematode.  In some cases, product combinations may provide protection from losses due to reniform nematode.
