摘要
为探讨50%热必斯WP对水稻稻瘟病的防治效果和适宜剂量,进行田间药效试验。试验结果表明:50%热必斯WP防治稻瘟病有较好的效果,穗瘟防效达67.1%～88.7%,试验剂量对水稻安全无害,可以大田推广应用,推荐用量为80～100g/667m2,在水稻破口期和齐穗期各用药一次。
In order to discuss the control effectiveness and suitable dosage of 50 % waterable powder ＂Rebisi＂ on rice blast, an experiment was conducted in field. The results showed that this powder had a good control effectiveness （67.1% -- 88.7 % ） on rice blast and the applied dosage had no harm to rice, which can be extended in large scale. The recommended dosage is 80- 100 g/667m2, which wiUbe applied twice in rice flower-breakthrough stage and ear-totally stage.
