植物源农药用于蔬菜种子丸粒化包衣研究初报

A preliminary study of applying botanical pesticide to vegetable seed pelletization

使用自制丸粒化配方包衣青菜和花椰菜种子,测试种子发芽状况及田间使用效果。室内试验表明,丸粒化包衣青菜和花椰菜种子的发芽势、发芽率、苗高、根长与对照没有显著差异,常温干燥贮藏2年,丸粒化包衣处理对青菜和花椰菜种子发芽率和发芽势没有影响;田间药效试验表明丸粒化包衣处理降低了青菜和花椰菜种子苗期猝倒病发病率,减少了小地老虎危害率。

The germination tests for the pelleted pakchoi and cauliflower seeds were conducted. The laboratory experiment showed that their germination vigors and rates, seedling heights and root lengths were not significantly different from those of the control, and after two years of dry storage in normal temperature, the pelleted seeds did not decrease in germination vigor and rate. The field trial showed that applying botanical pesticide to vegetable seed pelletization reduced the incidence of damping-off in pakchoi and cauliflower seedlings and the damage by black cutworms.
