Abstract
A bstract: The an tifungal efficacy of camazeb (fungicide) was determined on damping off disease of tomato caused by Rhizoctonia solani. Tomato seeds we re planted in the soil samples ( 1.5 kg each) in which six different concentrations of camazeb (0.00, 0.25, 0.50, 1.0 0, 2.00 and 4.00 g/100ml) was applied and inoculated with or without Rhizoctonia solani . Plants were observed on the 30th day. Rhizosphere bacteria were isolated after 30 days of germination and harvesting. I n vitro inhibitory effects of the isolated bacte ria were compared with camazeb against Rhizoctonia solani . Damping off disease led to the death of tomato seedlings where R. solani was inoculated. It was observed that plants were healthy at 0.25g/100ml of camazeb in soil inoculated with R. solani . However, higher concentrations of camazeb (2.00 and 400g/100ml) were detrimental to tomato seedlings. Colony count of bacteria reduced from 14 ± 4.0 × 10 3 cfu/g at 0.00g/100ml to 5 ± 1.0 × 10 3 cfu/g at 4.00g/100ml of camazeb. The bacteria isolated from rh izosphere soil were Pseudomonas aeruginosa, Bacillus thuringiensis, B. lentimorbus and B. subtilis. Pseudomonas aeruginosa had higher zone of inhibition (38.80mm) against R. solani than camazeb (23.83mm) at 4.00g/100ml. Therefore, Pseudomonas aeruginosa ma y be exploited as biocontrol agent of Rhizoctonia solani . Ekundayo FO, Hassan, GF .
