The nematicide imicyafos applied to Malabar spinach (Basella alba) showed high control effect on the root-knot nematode. The agrochemical residues in the Malabar spinach were 0.04 ppm at the stems and leaves and 0.10 ppm at the broad leaves after 30 days of soil-mixing treatment; later, the imicyafos residues gradually decreased. Here we discuss the application for the registration of imicyafos for use in Malabar spinach.
