近年我省稻田化学除草面积已达1300万亩,约占水稻栽插面积的87％。由于部分稻田长期使用单一的除草剂种类,导致除草效果日益下降,急需寻找替代的除草剂新品种。 昆明市植保值检站与有关单位协作,通过对30多种除草剂的杀草谱、持效期、安全性、使用成本、药剂来源以及同各种国内外除草剂进行对比分析,研究开发出一种新型的二元复配稻田除草剂——“昆明2
In recent years, our province rice chemical weeding area has reached 13 million mu, accounting for about 87% of rice planting area. Due to the long-term use of a single herbicide species in some paddy fields, the herbicidal effect has been declining day by day, so it is urgent to find alternative new herbicide varieties. Kunming Plant Protection Inspection Station in collaboration with the relevant units through more than 30 kinds of herbicides to kill grass spectrum, duration, safety, cost, source of pharmaceuticals and various domestic and foreign herbicides were analyzed and compared to study and develop A new binary compound rice herbicide - "Kunming 2
