Can tribenuron-methyl be used for weeding in pepper field?

Bensulfuron-methyl is a herbicide, which is mainly used to control broad-leaved weeds in wheat (winter wheat, spring wheat, barley, etc.). ) cropland.

Because the use of herbicides in pepper fields often kills pepper seedlings by mistake, it is suggested that it is best not to use herbicides in pepper seedling fields. If the pepper planting area is not very large, it is best to weed manually.

However, the workload of manual weeding is heavy, and it will be restricted by the weather, so the actual effect is not ideal. Therefore, it is necessary to use herbicides in pepper fields. Rational use of herbicides in pepper field can increase the yield of pepper by more than 65,438+00%. Here are some common herbicides for growing peppers.

Trifluralin is also known as solanine, Teflon and polytetrafluoroethylene. It is a toluidine selective exposure systemic herbicide with the characteristics of high efficiency, low toxicity, low residue and long residue period. The main dosage form is 48% EC.

Trifluralin can control most monocotyledonous weeds and a few dicotyledonous weeds, such as barnyard grass, wild oats, green bristlegrass, crabgrass, Spatholobus suberectus, cattail, thrush, Kentucky bluegrass, Bromus, purslane, erigeron breviscapus, Chenopodium and Tribulus terrestris. Pesticides should be applied before transplanting dried peppers and before covering plots with plastic films.

Use trifluoling to control weeds in dry pepper fields. The dosage is 30 ~ 40kg of water every 6672 100 ~ 150ml, spray it evenly, and then rake the ground flat, or rake it flat with a vegetable rake, and the liquid medicine will be mixed into 3 ~ 5cm soil layer in time.

Generally, trifluralin is applied before transplanting. It can also be applied before transplanted weeds appear. After application, it should also be leveled with a vegetable harrow in time to make the liquid medicine mixed into the soil to prevent photolysis and volatilization. Trifluralin is effective in controlling budding grass, but not for big grass, so it should be applied before weeds germinate.

Jingcaoke is also called quizalofop-ethyl, and its processing dosage form is 5% emulsifiable concentrate.

When soil moisture and air relative humidity are high, it is beneficial for weeds to absorb and transmit fine grass. Long-term drought without rain, low temperature and air relative humidity below 65% are not suitable for pesticide application. Generally, it should be applied in the morning and evening. 10 is not suitable for application from morning to 3 pm. Pay attention to the weather forecast before application, and don't rain for 2 hours after application.

If there is rain recently after a long drought, apply pesticides after the soil moisture and humidity are improved after the rain, and if there are irrigation conditions, apply pesticides after irrigation. Although the application time was delayed, the efficacy was better than that before rain or irrigation.

Gaicaoneng is a newly introduced herbicide, the pure product is brown crystal, and the industrial product is orange liquid, which is slightly soluble in water and soluble in many organic solvents. Flammable, the commonly used commercial dosage form is 10.8% EC. Gaicaoneng is basically non-toxic to people and safe to use.

Gaicao is a selective post-emergence herbicide with systemic conductivity. Widely used in weeding of soybean, peanut, cotton, rape, sweet potato, watermelon and other crops. It has a strong killing effect on gramineous weeds and a long efficacy, but it is ineffective on broadleaf weeds and sedges.

After transplanting, dry pepper can be applied from the emergence of weeds to the peak of growth. The application effect is the best at the stage of 3 ~ 5 leaves of weeds. Every 667m2, use 10.8% covering energy EC 20 ~ 30ml, add water 20 ~ 30kg, and spray evenly.

In addition, Dilamin, Duole, Dahuili, Fucaolong, Jingstable Killing, Laso, Nongsida, Nahuojing, Sike, Herbicide Dan, Shibanbu, Jieletong and Weiba can all be used for weeding in pepper fields. You can decide which product you are satisfied with by trying it out.
