Behavioral Effects of Carbofuran and Phenamiphos on Pratylenchus vulnus. II. Attraction to Bean Roots

N. Marban-Mendoza, D. R. Viglierchio

Abstract


Pratylenchus vulnus (L[sub3], L[sub4], adults) are attracted to the roots of growing bean seedlings. The attraction is inhibited by treating the nematodes with solutions of carbofuran or phenamiphos at concentrations below those necessary to inhibit motility and dispersion. Nematicide treatments of plants without treatment of nematodes are ineffectual because nematodes are attracted equally well to treated and untreated seedlings. Key Words: root-lesion nematodes, non-volatile nematicides, mode of action.
