Comparative study of different application methods of 14C-Fosthiazate in tomato plants

A comparative study of different application methods of nematicide 14C-Fosthiazate was done for the uptake in tomato plants in two varieties Pusa Ruby and Pusa Early Dwarf. The application methods used for the research purpose are seed treatment, soil supplication and drip application in presence and absence of surfactant (Tween-80).It as found that percent absorption was the highest in the drip irrigation method in presence of surfactant. The percent uptake of 14C-Fosthiazate in two varieties of tomato plants was found to be higher in Pusa Early Dwarf in all the treatment methods.
