| Abstract/Contents: | "Ningnanmycin, a low risk bio-pesticide produced from fermentation byproducts of the soil actinomycete Streptomyces noursei var. xichangensis n. var, was evaluated for its in vitro activity against Sclerotinia homoeocarpa (the causal agent of dollar spot) and Colletotrichum cereale (the causal agent of anthracnose) using a three-fold dilution from 0.81 to 0.01 μg/ml. Two isolates of C. cereale and six isolates of S. homoeocarpa, including three isolates sensitive to demethylation inhibitor (DMI) fungicide and three isolates resistant to DMI, were selected for the assay. Triticonazole was included as a standard for comparison. The mean EC50 values of C. cereale, S. homoeocarpa DMI-sensitive isolates, and S. homoeocarpa DMI-resistant isolates were 0.30, 0.01 and 0.17 μg/ml for ningnanmycin compared to 0.98, 0.05, and 0.49 μg/ml for triticonazole, respectively. A positive correlation was detected between EC50 values of ningnanmycin and triticonazole for isolates of S. homoeocarpa. In the field efficacy experiments, Ningnanmycin 10% WP at 0.29 g/m2 applied on a 7-day interval provided the highest control followed by Ningnanmycin 10% WP at 0.15 g/m2 (7-day interval) and Trinity 1.69S at 0.32 ml/m2 (14-day interval) for both dollar spot and anthracnose. The results of in vitro sensitivity assays and field efficacy experiments demonstrate that ningnanmycin has activities against two major turfgrass pathogens and can provide similar levels of control compared to traditional fungicides." |
