| 摘 要： | 通过不同时期接菌诱发试验,得出水稻破口前10～20d是稻曲病菌侵入的敏感期;在不同时期用药防治试验中得出水稻破口前8～15d防治效果最好。据此提出单季晚稻稻曲病的防治适期为水稻破口前10d左右进行。

| Abstract: | The inoculation experiments at different rice stages revealed that t en to twenty days before heading stage of rice was the sensitive stage of Ustila ginoidea virens infections. And the pesticide control experiments in different s tages indicated that the best control effect could be achieved from eight to fif teen days before heading stage of rice. Thus, the control of rice green smut in late single planted rice fields should be applied ten days before heading stage of rice. |
