Evaluation of Two Soybean Cultivars and Aldicarb Treatment in Soil Infested with Plant-parasitic Nematodes.
The soybean cultivars Davis and Leflore were grown in a northern Florida experimental site infested with eight species of plant-parasitic nematodes. Meloidogyne incognita appeared to become the predominant pathogen, suppressing Davis soybean yield regardless of aldicarb treatment. Soybean yields of Leflore were 1.4-fold to 3.5-fold greater than yields of Davis, but aldicarb did not affect yields of either cultivar. Davis soybean yield was negatively correlated with the at-plant density of M. incognita, whereas Leflore seed yield was not negatively correlated with any nematode.
