Brazil Parana state to cut soybean insecticide use
Apr. 24, 2008
The Brazilian state of Parana’s Ministry of Agriculture, the Seab, is seeking to lower the use of insecticides on soybeans. The Seab is considering implementing in the major soybean-growing state, an IPM system that cut insecticide use in the 1980s. It follows a proposal from the Brazilian agricultural research corporation, the Embrapa. The aim is to cut insecticide use on soybeans, maize and wheat by 30%, and increase by 10%, the use of biopesticide controls against velvetbean caterpillars (Anticarsia gemmatalis).
The corporation’s agronomists point out that farmers’ use of zero tillage is correct practice, but their application of pesticides is “unsuitable”. Farmers are using a mixture of herbicides and insecticides when they should be using only a herbicide. The indiscriminate use of insecticides is killing soybean pests’ natural predators, they explain. The practice is leading to yet higher application costs in subsequent seasons.
The Seab is also to monitor the marketing of all pesticides in real time. Data will be sourced from points of sale across the state and processed through an online network by the end of the year. The system (Siagro) will assess the quantity of pesticides sold, by target crop and pest or disease. The Ministry’s input inspection service, the DSI, says that such controls are impossible under current practice.
