Abstract

The effect of the plant resistance inducer acibenzolar-S-methyl on in vitro mycelial growth and sporulation of Curvularia eragrostides was evaluated, as well as the time and dosage of its application for the pathosystem yam x C. eragrostides. Five concentrations: 250; 125; 62.50; 31.25 and 15.12 ppm were evaluated for mycelial growth and sporulation of C. eragrostides. The ASM was sprayed onto the leaves of yam plants, at a concentration of 10 g, 20 g, and 30 g of the active ingredient (i.a.) per 100 liters of water, at time intervals of 10, 15, and 30 days before pathogen inoculation. Mycelial growth and sporulation of C. eragrostides was not affect by ASM, at the concentrations of 62.5; 31.25, and 15.12 ppm. Application of ASM was most effective at the dose of 15 g a.i./100 l of water, at 15 days before pathogen inoculation, providing protection against C. eragrostides, with a decrease of up to 76.15 % in yam leaf spot severity.

Abstract

This research aimed to evaluate the secondary effects of secondary metabolites produced by streptomycetes on spore germination and mycelial growth of the phytopathogenic fungi Cladosporium fulvum Cooke and Fusarium oxysporium f. sp. lycopersici from tomato plants. Metabolites produced by streptomycete isolates codified as AC-147 and AC-92 caused 94.1% inhibition of C. fulvum while AC-95 isolate caused 33.9% inhibition. AC-92 was the most efficient for F. oxysporum f. sp. lycopersici, causing 94.2% inhibition of spore germination. For mycelial growth, AC-26 and AC-92 were the most efficient in inhibiting C. fulvum growth by 46.6% and F. oxysporum f. sp. lycopersici by 29.9%. These streptomycetes are potential agents for biocontrol development methods of these tomato plant pathogenic fungi. [ABSTRACT FROM AUTHOR]
