Brazil Ag Ministry updates earworm control data
Five of the Brazilian states that declared a one-year plant health emergency due to the infestation of earworms (Helicoverpa armigera) have since extended the period by a year. The first extension came late last year in Goais state. Alagoas, Bahia, Minas Gerais, Maranhão and Mato Grosso are also implementing measures permitted through the 2013 decree. That allows growers in participating states to use imports of emamectin benzoate insecticide products. The Ministry has formed an “emergency state management group”. It has issued on its website recommendations to growers. They include adoption of pest emergency IPM measures, the integration of various control technologies, monitoring efforts such as studying weather, the development of plants and any damage, and to carry out the planting of cotton, maize and soybeans in the shortest possible period in order to reduce the pest’s potential consumption period.
