Fluroxypyr is an organic heterocyclic selective systemic conduction post-emergence herbicide. Its common name is fluroxypyr, and other names include herbicide. It is suitable for controlling wheat, barley, corn and other gramineous crops in the field Various broadleaf weeds. The preparation is 20% emulsifiable emulsifiable oil, the appearance is light brown or brown liquid, and the storage stability period is above 2a at room temperature.

Features of Fluroxypyr

1. Quick-acting, there is no doubt about it, its speed is close to that of paraquat, which has been banned, and comparable to it, so it is said to be weeding fast.

2. High safety, after 6 leaves of corn, 2-3 leaves of weeds, use 20% emulsifiable oil, use 50-60 ml per mu, mix water and spray, it will react in the plant body and combine to form a conjugate, Finally, it loses its toxicity, and at the same time, it is easy to degrade in the soil, and finally loses its activity, and will not have any impact on the next crops.

3. Good compatibility, currently the most famous one is 22% chlorpyrifos. It is a new type of herbicide independently developed by Qingdao Qingyuan Compound Co., Ltd. in my country. Of course, it can also be mixed with various herbicides such as 2-methyl-4-chlor, 2,4-butyl butyl ester, cyhalofop-ethyl and so on.

Although fluroxypyr has good quick-acting properties, its duration of action is as short as 15-20 days like that of paraquat; and the effect is not good if the temperature is lower than 10°C.

Applications of Fluroxypyr

Pyridyloxyacetic acid herbicides. It has a systemic conduction effect and a typical hormone-type herbicide response. When used post-emergence, sensitive crops show typical hormonal herbicide responses. It has a wide application period on cereal crops, and can be used to control broad-leaved weeds in wheat, barley, corn, grapes, orchards, pastures, forest farms, etc., and is ineffective against gramineous weeds. If it is used for winter wheat, it should be applied after the greening period after winter, and spring wheat at the 2-4 leaf stage. Use at the leaf stage. It can also be mixed with many other herbicides such as 2,4-D, 2-methyl-4-chlor, isoproturon, chlorotoluron, diclofop, and grass net.

Fluroxypyr is used to control most broad-leaved weeds in wheat fields. Most of the herbicides are mixed with other herbicides when used to expand the herbicidal spectrum and improve the herbicidal effect. Mixed with sulfuron and other herbicides. Fluroxypyr was administered before the wheat clover from Yixin to jointing, and the safety was relatively good.

How to use fluroxypyr

(1) Control and control of weeds in wheat fields: use 20% fluroxypyr isocyanate per acre during the post-winter greening stage of winter wheat or the tillering stage to the early jointing stage, the 3-5 leaf stage of spring wheat, and the 2-4 leaf stage of broad-leaved weeds. Octyl ester EC 50-66.7 ml, spray on water.

(2) Prevention and control of weeds in cornfields: before the 6-leaf stage after corn seedlings, at the 2-5 leaf stage of weeds, use 50-66.7 milliliters of 20% fluroxypyr isooctyl emulsifiable concentrate per mu to spray water; 66.7-100 ml of 20% isooctyl emulsifiable concentrate of fluroxypyr for mu.

(3) Control weeds in grapes, orchards, non-cultivated land and rice field ridges: In the 2-5 leaf stage of weeds, use 75-150 ml of 20% fluroxypyr-ethyl isooctyl EC per mu and spray on water. Use 50ml of 20% isooctyl fluroxypyr emulsifiable concentrate per acre, or mix 20ml of 20% isooctyl fluroxyfluroxypyroxylate emulsifiable concentrate with 200ml of 41% manganese bar water, or 20 Mix 30 ml of % fluroxypyr isooctyl emulsifiable concentrate with 150 ml of 41% manganese water. Mix 80-100 ml of 20% fluroxypyr isooctyl emulsifiable concentrate with 100-150 ml of 41% manganese water per mu.

2. Mixed use.

The mixed use of fluroxypyr isooctyl emulsifiable concentrate with other herbicides can expand the herbicide spectrum and reduce the cost. In the wheat field, use 30-40 ml of 20% isooctyl emulsifiable concentrate of fluroxypyr, add 35 ml of 72% 2,4-D-butyl ester emulsifiable concentrate or add 150 ml of 20% dimethyl tetrachloride water agent to effectively prevent miscellaneous Grass. Using 50-66.7 ml of 20% isooctyl emulsifiable concentrate per mu plus 50-67 ml of 6.9% puma water emulsion can effectively prevent and control wild oats, oatmeal, hard grass, clubhead grass, barnyard grass, horse Tang, Qianjinzi and other grass weeds.

Precautions for fluroxypyr

1. When spraying, add 0.2% non-ionic surfactant to the clofluroxypyr isooctyl emulsifiable liquid to improve the efficacy.

2. The pesticide should be sprayed when the temperature is low and the wind speed is low. The relative air humidity is lower than 65%, the temperature is higher than 28°C, and the wind speed exceeds 4 m/s.

3. When applying pesticides in orchards, avoid spraying the isooctyl fluoride emulsifiable concentrate solution directly on the fruit trees; avoid using isooctyl fluoride emulsifiable concentrate in tea gardens, banana gardens and nearby plots.

4. The sprayer that has been sprayed with isooctyl emulsifiable concentrate of fluroxypyr should be thoroughly cleaned before being used to spray other pesticides in broad-leaved crop fields.
