- In vitro evaluation the toxicity in mixture of glyphosate and methyl metsulfuron against strains of Trichoderma spp Johana Patricia Ramírez-Olier Hernán David Gómez-Berrio Juan Alberto Trujillo-Salazar Dora Luz Delgado-Gómez Claudia Sirley Rivera-Zuleta Liliana Rocío Botero Ingeniería methyl toxicity herbicides antagonims glyphosate Trichoderma is an antagonist fungus used in agriculture and forestry for the diseases control. The use of the herbicides metsulfuton methyl and glyphosate is a common practice for weed control that limits Trichoderma use. This study has evaluated the toxic effects of the herbicides metsulfuron methyl and glyphosate on four strains of fungi of the genus Trichoderma (GRB-HA1, GRB-HA2, GRB-HA8 and GRB-HA9). Poisoned media were prepared with high doses of 25 mL·L-1 of glyphosate + 0.2 g L-1 of metsulfuron methyl (D500) and low doses of 12.5 mL·L-1 of glyphosate + 0.2 g L-1 of methyl metsulfuron (D250) to determine the effects on viability. The effects of the exposure time (30-90 min) on the germination of the conidia were determined using suspensions prepared with the mixtures D500 and D250. The results showed the differential sensitivity of the Trichoderma strains that affected the viability of the conidia and mycelial growth. 2021 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49671325027 https://www.redalyc.org/journal/496/49671325027/ https://www.redalyc.org/journal/496/49671325027/html/ https://www.redalyc.org/journal/496/49671325027/49671325027.epub https://www.redalyc.org/journal/496/49671325027/movil 10.7440/res64.2018.03 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.218 Vol.88
