Brazilian IPM studies show drastic cut in agchem use
The use of IPM measures in Brazil has drastically reduced applications of pesticides in Brazilian trials, according to an agricultural research corporation, the Embrapa, study. Initial results from three years’ research on the application of such measures on farms in Mato Grosso state have revealed a “drastic cut in insecticide, fungicide and herbicide use”. Lead researcher Fernando Mendes Lamas notes that “depending on the production system, for example on soybeans, a ‘good desiccation’ can cut the number of post-emergence herbicide applications. Various systems are being studied involving summer crops, cotton, maize and soybeans, and autumn/winter crops, beans, wheat, oats and maize, based on tillage. “The species used for soil cover have a marked impact on weed control," Mr Lamas says.
