Abstract

The insecticide application techniques on cotton were compared in a series of trials. The new techniques compared well with knapsack sprayers and can play an important role in the control of Heliothis and other insect pests of cotton in Zambia. The ‘Electrodyn’ knapsack and ULV sprayers gave similar yields and pest control with cypermethrin at 30 g a.i./ha. A new pyrethroid lambda cyhalothrin (12 g a.i./ha) gave similar yields to cypermethrin (30 g a.i./ha) irrespective of the spraying techniques (Electrodyn, knapsack and ULV). The new application techniques have more potential for small-scale cotton farmers in developing countries as they receive limited training on the dilution of insecticides with water and calibration of knapsack sprayers.

Résumé

Les techniques d'application d'insecticides étaient comparées dans un série d'essais. Les nouvelles techniques semblaient favorables comparées aux pulvérisateurs dorsales et peuvent jouer une rôle importante dans la lutte contre Heliothis et d'autres insectes nuisibles au cotonn Zambie. Le pulvérisateurs Electrodyn, le pulvérisateur dorsal et les pulvérisateurs ULV donnaient des récoltes comparables, aussi bien que des contrôles semblables avec cypermethrin à 30 g a. j./ha. Une nouvelle pyréthroide lambda cyhalothrin (12 g a.j./ha) donnait des récoltes semblables a cypermethrin (30 g a.j./ha) indépendant de la technique d'application (Electrodyn, dorsal, et ULV). Les nouvelles techniques d'application ont un potential important pour les cultivateurs de coton a petite échelle dans les pays en voie de développement, puisqu'ils ne reçoivent qu'un entrainement limité concernant la dilution d'insecticides avec de l'eau et dans la calibration des pulverisateurs dorsales.
