| Abstract | ||
| A greenhouse experiments was conducted to determine the efficacy of benomyl as a fungicide, bioagents (Pesudomonas fluoresences, Pesudomonas cepacia and Bacillus subtilis), osmopriming seed treatment and their combinations to control Fusarium culmorum damping-off on wheat and barley seeds. The results showed that all the tested bacteria had an inhibitory effect against the growth of F. culmorum on culture medium. In autoclaved soils, none of the tested treatments affected the percentages of germination of either wheat or barley seeds. On the other hand, all the tested treatments were significantly decreased the time required to attain 90% of final emergence (T90) by 20.6–36.5% on wheat and 23.3–45.2% on barley. Benomyl and the tested bacterial isolates either individual or in combination with osmopriming improved wheat and barley. Therefore, the combination of osmopriming seedand antagonistic bacteria can be used in integrated pest management programes. | ||
