在水稻(Oryza sativa L.)4叶或丛生千金子[Leptochloa fascicularis(Lam.)Gray]5叶期使用除草剂噁草丙[ethyl2-(4-(6-Chlorn-2-benzoxazoly loxy)-phenoxy)propanasate],结合早期使用传统除草剂敌稗[3′4′,-dichloropronpionanilide],可有效地防除稻田恶性杂草丛生千金子。噁草丙对水稻植株有轻微至中度损伤。
The herbicide ethyl2- (4- (6-Chlorn-2-benzoxazoly loxy) -phenoxy was used in the leaf stage of 4 leaves or Leptochloa fascicularis (Lam.) Gray of rice (Oryza sativa L.) ) propanasate, combined with the early use of the conventional herbicide propanil [3’4 ’, - dichloropronpionanilide], can effectively control the malignant overgrowth of paddy fields. Bittergrass has mild to moderate damage to rice plants.
