EFFICACY OF TRICHODERMA-BASED COMMERCIAL PRODUCTS IN CONTROLLING FUSARIUM ROOT ROT ON COMMON BEANS

摘要

Fusarium root rot caused by Fusarium solani f. sp. phaseoli (Fsp) is a widely distributed disease of common bean in Brazil, especially in irrigated areas. Seed treatment with fungicide, crop rotation, and reduction of soil compaction are among the main strategies to control the disease (Abawi and Pastor-Corrales, 1990). One of the most effective fungicides for chemical seed treatment against Fsp is fludioxonil. Interest in biological control has increased because of concerns about the economic, environmental, and health costs of chemical crop protection practices. Trichoderma species are among the fungi with the highest potential for soilborne disease control. The aim of this study was to test the efficacy of six Trichoderma-based commercial products (TCP) available in Brazil for Fusarium root rot control.
