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