Response of Soybean Cultivars to Nematicidal Treatments of Soil Infested with Meloidogyne incognita
Abstract
A comparison of untreated and nematicide-treated soil for soybean production revealed that Meloidogyne incognita hastened crop maturity and reduced plant ht, seed wl, and yield. Reductions of yield varied from 32-90% depending on cultivar susceptibility. DBCP was more consistent in increasing crop performance than organo-phosphale or oxime carbamate nematicides. Greatest yield increases were produced by nematicidal treatment of soils planted to soybean cultivars with the lowest susceptibility. Key Words: Glycine max, control, resistance, toot-knot, population dynamics, nematode.Downloads
