Fungicide Resistance in Fusarium graminearum Species Complex

Magda Antunes de Chaves et al. Curr Microbiol. .

Abstract

Fusariosis affects cereal grain crops worldwide and is responsible for devastating crops, reducing grain quality and yield, and producing strong mycotoxins. Benzimidazoles and triazoles were recommended to combat fusariosis; however, there were reports of resistance, making it necessary to reflect on the reasons for this occurrence. The purpose of this review was to evaluate the fusariosis resistance to the main agricultural fungicides, to observe whether this resistance can cause changes in the production of mycotoxins, and to verify the influence of resistance on the cereal grain production chain. Scientific articles were selected from the ScienceDirect, Scopus, and Pubmed databases, published at maximum 10 years ago and covering the main fungicide classes that combat phytopathogenesis and mycotoxin production. A high occurrence of resistance to carbendazim was found, while few reports of resistance to triazoles are available. The effectiveness of strobilurins is doubtful, due to an increase of mycotoxins linked to it. It is possible to conclude that the large-scale use of fungicides can select resistant strains that will contribute to an increase in the production of mycotoxins and harm sectors of the world economy, not only the agriculture, but also sanitation and foreign trade.
