Is the emergence of fungal resistance to medical triazoles related to their use in the agroecosystems? A mini review BJM
Ribas e Ribas,Aícha Daniela; Spolti,Pierri; Del Ponte,Emerson Medeiros; Donato,Katarzyna Zawada; Schrekker,Henri; Fuentefria,Alexandre Meneghello.
Abstract Triazole fungicides are used broadly for the control of infectious diseases of both humans and plants. The surge in resistance to triazoles among pathogenic populations is an emergent issue both in agriculture and medicine. The non-rational use of fungicides with site-specific modes of action, such as the triazoles, may increase the risk of antifungal resistance development. In the medical field, the surge of resistant fungal isolates has been related to the intensive and recurrent therapeutic use of a limited number of triazoles for the treatment and prophylaxis of many mycoses. Similarities in the mode of action of triazole fungicides used in these two fields may lead to cross-resistance, thus expanding the spectrum of resistance to multiple...

Biological control of banana black Sigatoka disease with Trichoderma Ciência Rural
Cavero,Poholl Adan Sagratzki; Hanada,Rogério Eiji; Gasparotto,Luadir; Coelho Neto,Rosalee Albuquerque; Souza,Jorge Teodoro de.
Black Sigatoka disease caused by Mycosphaerella fijiensis is the most severe banana disease worldwide. The pathogen is in an invasive phase in Brazil and is already present in most States of the country. The potential of 29 isolates of Trichoderma spp. was studied for the control of black Sigatoka disease under field conditions. Four isolates were able to significantly reduce disease severity and were further tested in a second field experiment. Isolate 2.047 showed the best results in both field experiments and was selected for fungicide sensitivity tests and mass production. This isolate was identified as Trichoderma atroviride by sequencing fragments of the ITS region of the rDNA and tef-1α of the RNA polymerase. Trichoderma atroviride was as effective...
