abstract
Compatibility tests were conducted for triazole fungicides against entomopathogens, Beauveria bassiana, Metarhizium anisopliae and Lecanicillium lecanii @ 1, 10, 100, 1000, 10000ppm doses. Tebuconazole was highly toxic and completely inhibited the growth of all entomopathogenic fungi tested @ 1000 and 10,000ppm but with Lecanicillium lecanii growth was completely inhibited even at 100ppm. Difenaconazole and tricyclazole fungicides were less toxic to Beauveria bassiana and Metarhizium anisopliae but to Lecanicillium lecanii complete inhibition was recorded @ 100, 1000 and 10,000ppm and similarly 100 percent inhibition in tricyclazole was noticed only at 10,000ppm dose. Myclobutanil has a significant effect on the growth of all the fungi tested at 10,000ppm. Propiconazole fungicide was less toxic to Metarhizium anisopliae but was highly toxic to Beauveria bassiana and Lecanicillium lecanii @ 1000 and 10,000ppm treatments indicating that the triazole fungicides are not compatible with the entomopathogenic fungi tested @ 1000ppm and 10000ppm.
