Abstract
In vitro studies proved that oxamyl suppressed the hatching of Rotylenchulus reniformis eggs at concentrations varying from 5 to 500 ppm. Limited hatching took place at concentrations of 5, 10, 25 and 50 ppm while complete inhibition occurred at 500 ppm. The action was reversible but hatching potential was significantly reduced at concentrations of 10 ppm and above. Larval development was delayed in oxamyl. The development period in 0, 5, 10, 25, 50 and 500 ppm was 11, 14, 14, 17, 20 and 27 days for males and 13, 17, 17, 19, 22 and 29 days for juvenile females respectively, at 25 C.
