Experts want insecticide use cut on Brazil soya
Brazilian researchers are seeking to lower the use of insecticides for the control of lepidopteran pests on soybeans in the country. Companies in the product chain and researchers from universities and the agricultural research corporation, the Embrapa, met this month to discuss how to improve IPM practices. Insecticide use on soybeans has grown by 60% in the last decade. Embrapa Soja researcher Adeney de Freitas explained the concern. “We are trying to understand why farmers do not follow recommendations to apply pesticides only when some 20 caterpillars are detected per linear metre.” Researchers fear that farmers do not trust recommendations, adding that current practice could lower production and raise labour costs. “Indiscriminate applications raise concerns for the environment and increasing resistance,” he added.
