| Abstract: | Huangling EC7,a plant extract,in higher concentration (500 time dilution) showed strong and significant (5% level) inhibitive effects on seedling diseases caused by Fusarium spp.,Rhizoctonia solani and Alternaria tenus (82 63%,74 72% and 54.94% respectively). While lower concentration (1 000 time dilution) of Huangling EC7 and 25% cambendazim WC (500 time dilution) did not give control. In higher concentration (500 time dilution),Huangling EC7 exhibited inhibitive effects on seed germination,but did not have risk of damage in lower concentration (1 000 time dilution). |
