近期有农户反映旱稻前期使用噁草酮·丁草胺封闭处理,稻子出苗后发生药害,稻叶发白枯死,但根部很好,从图片来看,疑似噁草酮药害。考虑到近几年有公司推广噁草酮时发生大面积药害,损失巨大,现在简单来了解下噁草酮在水稻上的使用技术及注意事项。一、噁草酮主要用途噁草酮是选择性芽前、芽后除草剂,主要通过杂草幼芽和茎叶吸收而起作用,在有光的条件下能发挥良好的杀草活性。对萌芽期杂草尤为敏感,当 Recently, some farmers reported the use of oxalicum and butachlor in the early stage of upland rice. After the emergence of rice, phytotoxicity occurred. The rice leaves were white and withered, but the root was very good. From the picture, it is suspected that oxalic ketone damages the plant. Taking into account the company in recent years, the promotion of oxycodone a large area of ​​phytotoxicity, a huge loss, and now simple to understand the use of oxalicum on rice technology and precautions. First, the main use of oxacillin Malicarb ketone is a selective pre-emergence and post-emergence herbicides, mainly through the absorption of sprouts and stems and weeds play a role in the light conditions can play a good herbicidal activity. Particularly sensitive to germination weeds, when
