Manual de manejo de plantas daninhas resistentes em cultivos transgênicos

Abstract

In Brazil, the agricultural sector is one of the most important in economic and social terms, and its productivity indices are related to numerous factors. The adoption of alternative practices for the control of herbicide-resistant weeds is an increasingly present option in the day-by-day life of agricultural enterprises, however, both academic and professional circles still lack information on the subject. The objective of this work was to produce teaching material gathering technical information on the management and control of herbicide-resistant weeds in genetically modified crops. It was observed that information about the management of resistant weeds in transgenic crops is not available in a manner that is fully accessible to producers and professionals in the field, since effective management guidelines were not found in a single or few sources of information. Furthermore, there are resistant weed species whose control has been tested and achieved with the use of herbicides not prescribed for the specific control of these plants. From a perspective that has not yet been explored, it was possible to observe that management methods that are not very widespread in the agricultural sector, such as weed control using flamethrowers, may have great potential in resolving this problem. The research conducted allowed the collection of data to create a guide or other resource with more accessible, summarized and easy-to-understand information to be used on farms by technicians and farmers who need to manage herbicide-resistant weeds. Furthermore, the manual would be an effective tool to guide field professionals in control practices for these species.
