Soybean planting advances in Mato Grosso and the rural producer needs to be alert to the possible occurrence of pests in the crops. "These species are in the environment, in the crop. We had a recent cotton crop with high pressure from caterpillars, so if a pest occurrence was recorded in that area, the producer already knows the challenge they have to face now with the soybean," warns researcher Mariana Ortega, an expert in the field of entomology from the Foundation for Support of Agricultural Research of MT (Fundação MT).
