Abstract
Effects of antibiotics on the growth of four strains of biological control agents (BCA) B-916 (Bacillus subtilis), P7-14 (Pseudomonas fluorescens), P9409 (P. resinovorans) and P10353 (P. malculicola) were tested by growing them on peptone potassium nitrate medium (PPM) ranged from 0.5 to 1000 ug/mL of four antibiotitics: ampicilin, hygromycin, kanamycin and rifampicin. Antibiotics affected the growth of some BCAs but not others. Some BCAs were able to withstand high concentrations of antibiotics and thus their growth was not affected. Sheath blight of rice (Oryza sativa) caused by Rhizoctonia solani AG-I.1 was effectively controlled by the antibiotics, BCAs and mutants depending on the compatibility of the BCA and antibiotics. The three antibiotics at 50 ug/mL) reduced sheath blight by 60-80% as measured by area under the disease progress curve (AUDPC). B-916 and P9409 controlled the disease over 75%, whereas P7-14 and P10353 were less effective. B-916 + ampicilin, P10353 + rifampicin and P9409 + rifampicin. (25 ug/mL) was mixed with a BCA (0.5 X 10 7 CFU/mL) were sensitive resulted, disease suppression was consistently weakened.When an antibiotic and a tolerant BCA were combined as P7-14 + hygromicin and P9409 + hygromycin, their efficacy was unchanged or enhanced. Compared with the parent BCA, bio-control efficacy of hyg R -714 and hyg R -9409 was significantly enhanced (P<0.05) or unchanged in other cases.
