克无踪是一种触杀性强、杀草广、见效快、除草效果显著的灭生性除草剂,广泛应用于农田和非耕地的除草,深受人们的欢迎和喜爱。但克无踪在棉花脱叶和催熟上的应用研究,国内报道甚少,乙烯利作为棉花后期的催熟剂,对提高霜前花比例,加速棉铃吐絮进程,促使棉铃集中开放以利于采收和腾茬秋播起到了有效的作用。但该药成本高、催熟作用慢、受气候影响大的缺点,限制了其进一步的推广应用。为此我们于1993、2000年分别进行了以触杀型灭生性除草剂克无踪来取代乙烯
Traceless trace is a touch of herbicide, broad-spectrum grass kill, quick, herbicidal effect of significant herbicide, widely used in farmland and non-cultivated land weeding, welcomed by people and loved.

However, the high cost of the drug, slow ripening effect, shortcomings affected by the climate, limiting its further promotion and application. To this end, we carried out in 1993, 2000 were carried out in contact with the killing of non-viable herbicide without trace to replace ethylene
