| Description |
Nine insecticides were evaluated for their residual toxicity to leaf gall thrips (Liothrips Karnyi Bagnall) infesting black pepper (Piper nigrum L.). Initial toxicity was highest in monocrotophos which caused 90 per cent mortality up to 14 days after treatment. Monocrotophos continued to cause 50 per cent mortality up to 28 days after treatment. Monocrotophos and malathion caused some mortality up to 42 days after treatment. Analysis of PT (Persistence xToxicity) indices also indicated that residual toxicity was maximum in monocrotophos followed by malathion.
