| Abstract/Contents: | "Effect of an antagonistic bacterium AF-2001, Pseudomonas cepacia, on control of turfgrass diseases as brown patch, Pythium blight, dollar spot, and large patch were evaluated in vitro and in vivo. Results obtained in this study are summarized as follows. 1. Pseudomonas cepacia AF-2001 showed antagonism against to the pathogens causing brown patch, Pythium blight, dollar spot and large patch. Especially, the biological agent showed strong antagonistic effect on the causal pathogens of brown patch, dollar spot, and anthracnose, but weak on Pythium blight. 2. Population density of P. cepacia AF-2001 decreased rapidly in turfgrass soils. Initial populationof the agent was 2.4 × 107 cfu/g soil, however, decreased to 1.4× 103, 6× 102 and 0 cfu/g soil on 10, 20, and 30 days after application, respectively. 3. Under the controlled conditions of 27°C and 95% RH, P. cepacia AF-2001 showed 100% control efficacy on brown patch either by pre-treatment or post-treatment of infection. However, Pythium blight was controlled about 94% by pre-treatment and only 29% by post-treatment. 4. In filed trials, P. cepacia AF-2001 did not suppress large patch and the control efficacy on other turfgrass diseases was lower than agro-chemicals such as tebuconazole and metalaxyl. Control efficacy of brown patch, Pythium blight and dollar spot by the biological agent was 57.4%, 40.4%, 61.5~87%, respectively. 5. Growth, color, and texture of creeping bentgrass were not differ significantly between AF-2001 treatment and untreated control." |
