ATUALIZAÇÕES NAS RECOMENDAÇÕES E SUCESSO DO MANEJO DE MOFO BRANCO EM SOJA NA REGIÃO DE RIO VERDE – GO

Abstract

Brazil is one of the largest soybean producers in the world, where the State of Goiás stands out as one of the largest producers of this cereal of great economic importance. Despite the favorable edaphic-climatic conditions, several factors have hindered its production, mainly diseases caused by soil pathogens, which have increased its importance in intensive production systems. Among them, the white mold caused by Sclerotinia sclerotiorum (Lib.) De Bary, which is difficult to control, since the pathogen forms sclerotia (survival structures), which can remain viable for several years, and require integrated management, since there are no resistant cultivars. Therefore, this work aims to present a synthesis of the advances in the knowledge of the epidemiology of this pathogen, of the cultural, biological and chemical management in the soybean culture. The pathogen's resistance to fungicides is mentioned, mainly to fungicides from the benzimidazole group (methyl thiophanate and carbendazim). The use of biological control agents, such as Trichoderma spp. and Bacillus, has been studied in Brazil, reaching 80% control. Crop rotation with non-host white mold species is an alternative for white mold control.
