Levantamento do controle químico das pragas da soja (Glycine max L.) no cerrado piauiense

Abstract

Soybean (Glycine max L.) is one of the most important crops in the world economy. In Brazil, the crop is expanding in practically all regions, since the most recent producing region is MAPITOBA, which due to its favorable characteristics, has been a major highlight in the production of grains in the country. However, the great bottleneck faced in the country is in relation to the control of pests in the crop, which despite the products used are effective, 7 to cases of resistance of insect pests to doses of insecticides. Therefore, the objective of this work was to survey the effectiveness of the control of soybean pests (Glycine Max L.) in Cerrado Piauiense. The methodology was qualitative, descriptive and exploratory, with a theoretical approach, using semi-structured interviews, with producers from the Cerrado Piauiense region in the municipality of Uruçuí - PI, following the questions described in a questionnaire, which later Were analysed. The results and discussions have shown that although the control is momentarily effective, producers use chemical control tactics, with high dosages of insecticides, that deviate from the legal parameters, and indications of the manufacturers of these products, based on the average dosages / hectares used by the farms and the indications of the leaflets of each product, besides being also verified the use of products that are not registered for the soybean crop. However, it was concluded that producers of Cerrado Piauiense use chemical control tactics outside the standards, norms and recommendations indicated, but they were indispensable to guarantee the production of the region, even though the dosage is higher than indicated by the package inserts. can lead to a series of problems, from insect-pests, as well as economic, and environmental resistance.
