Brazil has granted emergency approval for three biopesticides for the control of corn earworms (Helicoverpa zea) on cotton and soybeans. They include two products from biopesticide company Bio Controle (Indaiatuba). It has authorisation to sell its viral insecticide, Gemstar LC (H zea nuclear polyhedrovirus - NPV) for the control of the pest, and its pheromone, Bio Helicoverpa (hexadecenal (z)-11 and (z)-9isomers), for monitoring purposes. Gemstar is formulated by Mitsui & Co subsidiary Certis USA, and Bio Helicoverpa by Costa Rican ChemTica Internacional. The Brazilian agricultural inputs business, CCAB Agro (Sao Paulo), was also granted authorisation to sell its H zea spp NPV product, Hz-NPV CCAB. It is manufactured by AgBiTech of Australia. A state of emergency was declared in Bahia state in April due to infestations of the pest on cotton and soybeans (Agrow No 660, p 19).
