Abstract
The use of bactericides and resistant varieties to control the bacterial wilt disease have been explored by Indonesian farmers but the pathogen is still difficult to control. The application of biocontrol agents (BCA) is an alternative measure to control the bacterial wilt disease of peanut. The experiments were conducted to study the effectiveness of Pseudomonas fluorescens RH4003 and Bacillus subtilis AB89 to control the bacterial wilt disease of peanut, and to detect some characters of several BCA. Six candidate BCA were evaluated for their effects on seed viability and the effectiveness to control the bacterial wilt disease of peanut in the green house. Disease index of the plants treated with the BCA was significantly different compared with the control but there were no differences among the BCA. Index suppression on six weeks after planting caused by 0.02% streptomycin sulphate, P. fluorescens RH4003, Bacillus sp. KS2, P. fluorescens CK5, B. subtilis AB89, P. fluorescens ES32 was up to 85.7, 83.5, 77.6, 75.3, 67.5, and 58.8 %, respectively. The percentage of seed viability up to 14 days was not significantly different compared with control. Seedling height and number of branches on the seeds treated with Bacillus sp. KS2 were significantly higher compared with those in control and another BCA treatments. Height of the plants treated with BCA were significantly higher compared with those in control treatment.
