Controling early season pests of cotton with seed treatment: First success of a regional Co-operation network
1993
Genay, Jean-Paul | Nouyen, Trung Bien
First step of this regional network was to investigate seed treatment as an alternative to the frequent aerial applications of usually toxic insecticides currently under practice in these countries for the control of early sucking pests (jassids: Amrasca biguttula Ishiga and aphids: Aphis gossypii Glover). The objective was to test, in an identical trial, the efficiency of some seed treatment insecticides under Thai, Lao and Vietnamese conditions. This trial, carried out during the 1992 rainy season, gave very comparable results at the three testing places. Of the four active ingredients screened, imidacloprid gave the best results, providing the young cotton plants with a good protection during the whole vegetative phase. Seed treatment could reduce the number of insecticides applications and be safer for the environment, fitting well within an IPM approach.
