| Abstract | ||
| The results of antagonistic activity of five isolates of Azotobaetar chroococcum showed that the isolates varied in their ability in reducing radial growth rate of R. solani . Azo.4 and Azo. 5 isolates showed significant reduction in radial growth rate ( 3.16, 3.03) cm respectively compared to control treatment ( 5.16 ) cm . Results of the effect of Azotobaetar suspension dilution on radial growth of R. solani revealed that the antagonistic activity was depend upon the isolate type and inoculum level .Azo. 4 and Azo. 5 isolates were the superior in all tested inoculum levels ( 10, 15 and 20 ) % which recorded (3.20, 3.13) cm (3.06, 3.03) cm and ( 3.0, 2.90 ) cm respectively compared to control treatment ( 5.0 ) cm. Results of greenhouse experiment showed that most treatments significantly increased tomato growth parameters ( shoot and root length ,dry and soft weight of shoot and root , no. of leaves and flowers /plant ), and decreased the percentage of infected tomato plants by R. solani ( pre and post emergency). | ||
