Influence of different nozzle on residual toxicity of insecticides against larvae of Cabbage butterfly (Pieris brassicae Linn.)
Keywords:malathion, quinalphos, residues, cabbage, persistence, waiting period
A study was undertaken to evaluate the Influence of nozzle on residual toxicity of insecticides against larvae of Cabbage butterfly (Pieris brassicae linn.) under temperate conditions of SKUAST-Kashmir, Shalimar. Three insecticides at different concentrations were evaluated in treatment @ 0.1, 0.05 and 0.025% for Dichlorvos, 0.14, 0.07 and 0.035% for Malathion and 0.07, 0.035 and 0.0175% for Quinalphos. Influence of nozzle in context to efficacy of each insecticide based on median lethal time (LT50), median lethal concentration (LC50), persistent toxicity (PT) and relative residual toxicity (RRT) of each insecticide was determined. The value of persistent toxicity was recorded highest (540.36) after the treatment of Dichlorvos 76 EC @ 0.10% followed by spray of Quinalphos 25 EC @ 0.07%, (430.10) sprayed whereas the lowest value (154.00) was recorded by treatment of Malathion 50 EC @ 0.035% sprayed. The relative residual toxicity was observed highest (3.34) in case of Dichlorvos 76 EC @ 0.10% sprayed followed by spray of Quinalphos 25 EC @ 0.07%, (2.77) were as the lowest (1.00) observed in case of Malathion 50 EC @ 0.035% sprayed. Dichlorvos recorded to be relatively more toxic than Quinalphos and Malathion. Malathion proved to be least toxic to the larvae of cabbage butterfly, and followed by quinalphos and Dichlorvos, as it is evident from the value of persistent toxicity and relative residual toxicity of each insecticide with respective concentrations.
