Relationship between preseason numbers of Meloidogyne incognita and yield losses in chile pepper cultivars
Yield losses in chile pepper (Capsicum annuum L.) cultivars 'Jalapeño,' 'New México 6-4' and 'Sandía,' resulting from parasitism by the southern root-knot nematode Meloidogyne incognita race 3 were evaluated in microplots during two growing seasons. Pre-plant inoculum densities (0, 50, 100, 200 and 500 M. incognita eggs and larvae/500 cm3 soil) were arranged in a factorial design with five replications within each cultivar. NM 6-4 fruit weight was reduced 40 percent by an initial density of 50 nematodes and damage thresholds for Jalapeño and Sandia fluctuated between 100 and 200 M. incognita/500 cm3 soil during the two seasons
