Chemical Control of Hoplolaimus columbus on Cotton and Soybean
AbstractSeven experiments, three on soybean and four on cotton, were conducted in Hoplolaimus columbus-infested soil in southern North Carolina to determine the benefits of chemical soil treatment. Locations were selected to give a range of initial population (Pi) densities. Soil fumigation with 1,3-D and soil treatment with a combination of aldicarb plus fenamiphos (1.1 kg a.i./ha) each provided good control of this nematode. Yield responses considered to be significant were achieved only on the high Pi site. Key words: chemical control, Columbia lance nematode, cotton, Glycbne max, Gossypium hirsutum, Hoplolairnus columbus, nematicide, soybean, 1,3-dichloropropene (1,3-D).
