Biological Control of Soybean Anthracnose by Pseudomonas sp.
Jeung Haing Oh, Kyu Hong Kim
Abstract
Pseudomonas sp. antagonistic to Colletotrichum truncatum and C. gloeosporioides was selected as a biological control agent for soybean anthracnose. Pseudomonas sp. inhibited the mycelial growth of pathogens effectively as the fungicides such as benomyl and fluazinam in vitro tests without any adverse effects on soybean. Seed treatment with the Pseudomonas sp. increased emergence rate of soybean seeds significantly after inoculation with C. truncatum. When the suspension of Pseudomonas sp. was sprayed on soybean plants, the control efficacy was not different from that of fungicides, benomyl and fluazinam two weeks after treatment, however the efficacy did not last long enough after three weeks.
Key Words: Biological control, Colletotrichum truncatum, Pseudomonas sp.
