Abstract

The invention relates to a picolinafen / fluroxypyr-mepthyl-containing weedicide composition. The weedicide composition has the synergistic actions. The weight ratio of the picolinafen to the fluroxypyr-mepthyl is 1:9-9:1, preferably 1:3-3:1, and most preferably 1:2.

Description

technical field [0001] The invention belongs to the field of herbicide compounding, and specifically relates to a herbicidal composition containing diflufenid and isooctyl fluroxypyracetic acid. The herbicidal composition has good weeding effect, is safe for crops, and lasts for a long time. long. Background technique [0002] Picolinafen is a pyridinamide herbicide developed by BASF, which was launched in 2002. Mainly used in corn, soybean and wheat fields to control a variety of annual grass weeds and some broad-leaved weeds. This variety is a selective contact and residual herbicide, and its mode of action is to hinder the biosynthesis of carotenoids through the inhibition of phytoene dehydrogenase. Compared with other pyridinamide herbicides, flupifenamide has the characteristics of high herbicidal activity, long duration, not easy to decompose, and safe to crops. [0003] Fluroxypyr, also known as fluroxypyr and fluroxypyr, is a systemic conduction type plant post-em...
