The antifungal effect of Suaeda fruticosa (L.), and Salsola imbricata Forssk. leaves were observed against root pathogenic fungi Macrophomina phaseolina (Tassi) Goid, Rhizoctonia solani (Kühn) and Fusarium oxysporum (Schlecht) using two different formulations namely capsules and pellets. unfilled shells of capsules were filled with leaves powder of S. fruticosa and S. imbricata whereas, equal amount of leaves powder and pyrophyllite were mixed and used to prepare pellets. It was found that 1 and 3 capsules/pot of S. imbricata and S. fruticosa boosted (P < 0.001) growth of both crop plants viz; cowpea and okra while all dosages of capsules significantly declined the incidence of root rot fungi.

In the field experiment results of growth parameters and suppression of root-infecting fungi were similar whereas, the chlorophyll content of the okra plant was significantly enhanced by using pellets prepared with leaves powder of S. imbricata. On the other hand, the chlorophyll content of the cowpea plant showed no significant improvement by using any of the formulations under field conditions. Hence, plant-based fungicides are better replacement of synthetic chemicals and healthier environment can be achieved by application of organic amendments.

摘要

The antifungal effect of Suaeda fruticosa (L.), and Salsola imbricata Forssk. leaves were observed against root pathogenic fungi Macrophomina phaseolina (Tassi) Goid, Rhizoctonia solani (Kühn) and Fusarium oxysporum (Schlecht) using two different formulations namely capsules and pellets. unfilled shells of capsules were filled with leaves powder of S. fruticosa and S. imbricata whereas, equal amount of leaves powder and pyrophyllite were mixed and used to prepare pellets. It was found that 1 and 3 capsules/pot of S. imbricata and S. fruticosa boosted (P < 0.001) growth of both crop plants viz; cowpea and okra while all dosages of capsules significantly declined the incidence of root rot fungi. Similar results were revealed in case of pellets in which 1 and 3 pellets/pot remarkably elevated (P < 0.001) growth of both crop plants as well as significantly inhibited growth of all three root-infecting fungi in screen house experiment. In the field experiment results of growth parameters and suppression of root-infecting fungi were similar whereas, the chlorophyll content of the okra plant was significantly enhanced by using pellets prepared with leaves powder of S. imbricata. On the other hand, the chlorophyll content of the cowpea plant showed no significant improvement by using any of the formulations under field conditions. Hence, plant-based fungicides are better replacement of synthetic chemicals and healthier environment can be achieved by application of organic amendments.
