Action of phosfon (tributyl-2, 4-dichlorobenzyl phosphonium chloride) on Meloidogyne incogoita*
Abstract
Application of phosfon at 500 and 1000 μg/plant minimised or prevented invasion of cowpea (Vigna sinensis (L) Savi) roots by Meloidogyne incognita larvae in experiment conducted in growth chamber at 27±1°C. The plants treated with 250 and 500 μg of phosfon produced significantly fewer eggs and egg masses. Phosfonas well as root diffusate from phosfon-treated plants reduced the hatch ability of eggs.
Carrot-root discs treated with phosfon 500 μg/plant were less attractive to M incognita in vitro.
