草克星(NC—311)是一种低毒,高效,用量少,杀草谱广,对水稻安全新型除草剂。在插秧田和直播田用药量每公顷10～30克范围内(有效成分)。如单用草克星插秧田在插后5～7天,直播田在播后3～10天(稗草在2叶期前)。与其它药混用时,草克星用药量10克/公顷,插秧田可于60%丁草胺750克或96%禾大壮1440克/公顷混合施用。直播田可于禾大壮1440克/公顷混用。可有效地防除稗草、鸭舌草、眼子菜、母草、扁杆藨草、三棱藨草、洋泻、野慈茹和牛毛草针(?)专多钟杂草.施药时可采用毒土、喷雾法,施药时水层3～5厘米,保持5～7天。草克星一次施药,可控制整个生育期稻田杂草.是插秧田和直播田较为理想除草剂。
Grass nemesis (NC-311) is a low toxicity, high efficiency, less dosage, broad spectrum of herbicides, a new herbicide for rice safety. In the transplanting and direct seeding field dose of 10 to 30 grams per hectare range (active ingredient). Such as single use of grass nectar transplanting seedlings in the plug after 5 to 7 days, live in the field after sowing 3 to 10 days (barnyard grass in the 2 leaves before). When used in combination with other drugs, the herbicide is applied at a rate of 10 grams per hectare. The seedling can be mixed with 60% butachlor 750 grams or 96% Wooshuang 1440 grams per hectare. Direct broadcast field can be strong at 1440 grams Wo heavy mix. It can effectively control weeds of barnyardgrass, monocotyledon, zygophila, motherwort, flat barnyardgrass, rhizome cucumerin, cathartes, wild charcot and prickly haired needle (?) Toxic soil can be used, spray method, when applied to the water layer 3 to 5 cm, to maintain 5 to 7 days. Grass nemesis a pesticide application, can control the entire growing period of weeds in paddy fields. It is an ideal herbicide for planting seedlings and direct seeding fields.
