Abstract
Studies on critical time of insecticidal protection in relation to damage by aphid, Aphis gossipii Glover and leafhopper, Amrasca biguttula biguttula Ishida on plant growth and yield of okra revealed that 21–42 days after germination, was the most critical time prior to fruiting. Application of carbofuran at the time of sowing was redundant. Effective plant protection 21–42 days after germination resulted in lowest leafhopper and aphid infestation and subsequently the highest benefit to cost ratio.
Résumé
Des études sur le temps critique de la protection d’insecticide en relation avec le ravage par des pous et des sauteurs de feuilles sur la croissance et le rendement de la plante en okra a révélé que 21–42 jours après la germination, d’être le plus critique avant la phase fruitière. L’application de carbofuran au temps des semilles était redondant. Dés méthodes effectives de la protection de plante 21–42 joure après la germination avait pour résultat la moindre infestation des sauteure de feuilles et des pour et par la suite le phis haut avantage économique.
