Manejo químico e genético de Stenocarpella sp. e Fusarium sp. em milho

Abstract

– Brazil is one of the world leaders in corn production and Mato Grosso is the largest national producer, with 33% of Brazilian production. In the state, one of the phytosanitary challenges is the issue of ear rot, caused by the fungi Fusarium sp. and Stenocarpella sp. ear rot causes health and storage problems, reduced grain and/or seed quality. In addition to nutritional problems, as the fungal complex releases mycotoxins capable of causing intoxication in animals and humans. In this sense, control technologies have been developed which involve a mixture of chemical molecules applied in the vegetative and reproductive phases, as well as the search for genetic resistance. In this sense, the dissertation was returned in two chapters. In the first one, a general consideration on ear rot in corn will be presented, from the contextualization of the disease and the characterization of the phytopathogenic agents, to the management strategies currently adopted. In the second, an attempt was made to establish a management protocol for ear rot in corn, caused by Fusarium sp. and Stenocarpella sp., for the region of Sorriso-MT, based on chemical and genetic control.
