Integrated Management of Southern Root-Knot Nematode with Resistant Cotton Varieties and Nematicides in Appling County, Georgia

Southern root-knot nematode (Meloidogyne incognita) is the most widespread nematode affecting cotton in Georgia and is a significant problem in Appling County.  With the loss of Temik and poor crop rotations due to current commodity prices, growers require new options to manage nematodes. This large-plot, on-farm study was conducted with objectives of assessing fumigation with 1,3-dichloropropene (Telone II) and the use of multiple varieties, to include Phytogen 487, ST 4946, DP 1553 and 1558. Each variety was planted to ground that had or had not been pre-fumigated with Telone II (3 gal/A).
