韩国原装进口水稻田除草剂韩乐天(1%韩乐天乳油)是目前水稻田茎叶处理除草剂中除草活性最高、杀草谱最广的一次性除草剂。对稗草、稻稗、野慈姑(驴耳菜)、泽泻(水白菜)、三棱草、稻李氏禾等杂草特效,一次用药基本可防除水稻田绝大多数杂草,省工省时省力。近几年,水稻田杂草对一些长期使用的除草剂已产生明显抗性,在加大用药量的情况下,药害加重仍达不到理想除草效果,且除草成本提高。但杂草对韩乐天尚未产生抗性,用药量较低,除草效果好,对水稻安全,是替代杂草已产生抗性除草剂的最佳选择。
South Korea imported rice paddy herbicide Han Lotte (1% Han Lotte EC) is currently the paddy leaf stem herbicide herbicidal activity of the highest, the most widely used herbicide to kill one-time herbicide. On barnyardgrass, rice barnyard grass, wild arrowheads (Ass donkey), Alisma orientalis (cabbage), Sanxiancao, rice Lee Wo and other weed special effects, a single drug can basically control most weeds in paddy fields, save time and energy. In recent years, paddy field weeds have some obvious resistance to some herbicides that have been used for a long time. Under the condition of increasing dosage, the weed injury still does not reach the ideal weeding effect and the weeding cost is increased. However, the weeds have not yet developed resistance to halotian, the dosage is low, the weeding effect is good, and the safety of rice is the best alternative to weeds that have produced resistant herbicides.
