Brazil adopts bio-insecticide for cassava:
Brazil's cassava farmers are to use a baculovirus-based bio-insecticide to combat the lepidopteran pest, cassava hornworms (Erinnyis ello). The Brazilian agricultural research corporation, the Embrapa, has adopted the emergency use of the bio-insecticide in the major cassava-producing state, Acre. The product was tested on 9,000 ha between March and April, and demonstrated a 95% mortality rate in hornworms if used when the pest first appeared. The "improper" use of insecticides reduced populations of the hornworm's natural predators in the 1990s, the Embrapa says.
