Integrated management of insect pests, diseases and weeds of cotton in Africa

Integrated Pest Management Reviews

Abstract

Integrated pest management systems were developed originally in response to the appearance of insect populations with resistance to common insecticides. Cotton with its heavy dependence on insecticidal sprays was one of the first crops in which the effectiveness of control declined due to resistance in the target pests. Although insecticide resistance is more of a problem in large scale production systems, the IPM approach can also benefit the smallholder by reducing the number of sprays required with consequent cost savings. Where crop growth is adversely affected by diseases, competition from weeds or poor management, the full benefit of insecticide spray programmes cannot be realised. To be fully effective, insect control should therefore be integrated with other crop protection activities. This paper reviews the insect pests, diseases and weed problems of cotton in Africa and discusses the possibilities for extending the principles of IPM to cover all the crop protection activities with practical examples drawn from both small scale and larger scale production systems.
