Cotton Insect Pest Problems and Management Strategies in Côte d’Ivoire, W. Africa
Mar 6, 2019
The current pest management recommendations have become critical in Côte d’Ivoire. Variations in major pest profiles such as Polyphagotarsonemus latus (Banks) and Helicoverpa armigera (Hübner), show that calendar treatments do not always relate to field conditions or actual pest pressure. Furthermore, since the removal of insecticide subsidies, concerns are rising regarding farmer awareness of rational pesticides use. Experimental strategies were designed to optimize farmer profits by using threshold treatments or to prevent pyrethroid resistance in bollworm by alternating insecticides in the calendar programme. Relevant strategies based on appropriate decision aids were shown to enhance the effectiveness of pest control and minimize risks of economic losses and pesticide resistance through on farm trials.
