Summary

This four-part presentation addresses scouting for and managing the major nematode species on soybeans and other row crops in the U.S. South. Nematode problems are widespread in the South and annually cause 5–10% yield losses for the total crop. Part 1 of this series of webcasts covers the biology and host ranges of various species of nematodes. Part 2 discusses nematode sampling and thresholds. Part 3 discusses resistant cultivars and crop rotation. Part 4 covers nematicides. After viewing these webcasts, practitioners should know more about the life cycles of the southern root-knot, reniform, soybean cyst, and Columbia lance nematodes and be able to design an appropriate scouting and management program.​
