Brazil states reject emamectin earworm control
Two Brazilian states have opted not to approve the emergency sale and use of the insecticide, emamectin benzoate. Mato Grosso do Sul’s plant protection office, the Iagro, has followed the advice of the public prosecutor, which recommended suspension of authorisations and sought a legal challenge against its approval (Agrow No 686, p 16). That followed the state’s declaration of a state of emergency against earworm (Helicoverpa armigera) infestations on its cotton and soybeans (Agrow No 679, p 20). Parana’s plant health office, the Adapar, has also declined to approve the active ingredient. National legislation permits such states to approve the use of the insecticide as an emergency measure (Agrow No 677, p 17).
