Effect of adjuvants, fungicides and insecticides on the growth of Trichoderma koningiopsis Th003

Abstract. The effect of 44 agrochemicals (fungicides, insecticides and adjuvants) on the mycelial growth and germination conidia of Trichoderma koningiopsis Th003 was determined by seeding of 5 mm discs of fungal mycelium in Sabouraud agar supplemented with each agrochemical and seeding of conidia suspended in solutions of agrochemicals in water agar. For the adjuvants, their effect on the phyllospheric establishment of T. koningiopsis Th003 was determined by following their population in cape gooseberry leaflets inoculated with the fungus suspended in them. Eight fungicides did not inhibit the fungus mycelial growth or the conidia germination. Fenhexamid - Tebuconazole, Flutriafol and Kasugamicina inhibited it between 34 and 48% without affecting germination, Thiram - Pyrimethanil, Prochloraz, Tiabendazol, Spiroxamina and Triadimenol - Tebuconazole inhibited the growth and Thiram - Pyrimethanil and Dodine did not allow conidia germination. Insecticides and adjuvants presented an inhibition of up to 70% but did not affect the conidia germination. No negative effects of the adjuvants on the phyllosphere establishment of T. koningiopsis Th003 were observed, recovering from the treatments approximately 1x103 CFU g-1.
