Characteristic range and low temperature effect of herbicides for weed control in fluroxypyr

Cloflupiroxicam is a post-emergence herbicide, which can be quickly absorbed by plants after application. Can be used for preventing and killing Rhizoma Corydalis, Polygonum hydropiper, Herba Portulacae, Solanum nigrum, Herba Stellariae Cirrhosae, Commelina communis, Herba Elsholtzia, cabbage, broad bean, Descurainia sophia, and small convolvulus. It has no residue on the soil and will not affect the following crops. The half-life of fluroxypyr in soil is only 1 1 day.

The characteristics of fluroxypyr

Cloflupiroxicam is a kind of hormone herbicide specially used to control broadleaf weeds. Cloflupiroxicam is a hormone herbicide with strong systemic effect.

After spraying drugs on weeds, weeds will be poisoned, mainly manifested in plant deformity, distortion and finally death.

Moreover, fluroxypyr has good compatibility. At present, the most famous herbicide belongs to 22% chlorpyrifos-dimehypo, which is a new herbicide independently developed by Qingdao Qingyuan Compound Co., Ltd. Of course, herbicides such as 2 methyl 4 chlorine, 2,4 drops of butyl ester and cyhalofop-butyl can also be mixed.

Cloflupiroxicam is quick-acting, but its duration is only about 15 ~ 20 days, just like paraquat. Moreover, the low temperature effect of clopidogrel acetic acid is not good below 10℃.

Weeding scope in fluroxypyr

When using fluroxypyr, we should know which weeds are abundant in our fields, so as to suit the remedy to the case and get twice the result with half the effort.

Because chloroglycolic acid is only effective for broadleaf grass, but not for Gramineae and sedge. Therefore, it is reasonable to buy the right medicine, not the expensive medicine.

Common broad-leaved grasses: pig seedlings, purslane, sogou, shepherd's purse, thistle, millet, amaranth, black nightshade, Alternanthera philoxeroides, Maijiahong and so on.

Which crops are suitable for fluroxypyr?

After knowing that it mainly controls broad-leaved weeds, let's see which crops it is suitable for. It can be applied to broad-leaved weeds in gramineous crops such as wheat, corn, rice, grapes and orchards.

The advantage of clopidoxyacetic acid is that it acts quickly, almost as fast as paraquat which has been banned. Therefore, the weeding speed is fast and the safety is high.

For example, corn, after its 6 leaves, weeds 2 ~ 3 leaves, with 20% chlorhexidine EC, 50 ~ 60 ml per mu, sprayed with water. It will react in plants, combine into conjugates, and finally lose its toxicity. At the same time, it is easy to degrade in soil, and finally loses its activity, which will not have any impact on the next crop.
