Phenamiphos was found to supress hatch from eggs of Meloidogyne iucognita. The percentage hatch was found to be inversely related with increase in concentration and exposure period. Penetration of J2 into cowpea roots was significantly reduced when J2 were exposed to sublethal concentration of 0.0005 to 0.0200 μg/ml phenamiphos for 24 or 48 h.
