Farmers zero-in on insect pests. Validated RNRRS Output.

Abstract

This is one of 280 summaries describing key outputs from the projects run by DFID's 10-year Renewable Natural Resources Research Strategy (RNRRS) programmes.

Principally based on Projects R6684, R7486 and R8265. Armed with new knowledge, farmers are taking action to reduce damage to crops in storage. A risk warning system, based on a model of insect flight activity and climate data, enables extension services to warn them of anticipated increases in the threat from a pest known as the larger grain borer (LGB). In addition, using targeted insecticide applications, farmers can reduce by at least 70% the amount of pesticide applied to their crops, zeroing-in on the portion they will be consuming during the storage season. LGB can be devastating to maize and dried cassava. Without a warning system, the sporadic nature of LGB outbreaks can take farmers by surprise. The new techniques, developed and validated in Ghana and Tanzania, cut losses—and costs—considerably.
