Hubei Xiaogan Shangjun, via SMS (158****9742) March 7 Q: Weeding on broad beans, what kinds of herbicides can be selected? What medication techniques should we pay attention to?
Zhou Zhiyuan, Marketing Manager of Shandong Shengbang Greenfield Chemical Co., Ltd. A: Many products can be used. It is necessary to control them in stages and the effect is good. The product is recommended to be tested before large-scale promotion and application.
Most of the broad bean is live, the growth period is generally longer, and the symbiosis period with weeds is also long. In addition, the growth stage of broad beans is the weeds prosperous period. There are many types of weeds, and the amount of weeds is large, causing serious damage. Post-emergence chemical weeding can generally use the following herbicides:
120% chlorene emulsifiable concentrate. For grassy weeds in the 2-5 leaf stage, use 67-100 ml of liquid per acre and add 40-50 liters of water to evenly spray weed stems and leaves. For the control of perennial grass weeds or higher weeds, the above dose can be increased by 30-50 ml.
215% fluazifen or 35% pirfenrazin. In the 2-3 leaf stage of weeds such as goosegrass, crabgrass, and valerian, use 33-50 ml/mu, 4-6 leaf, use 66-80 ml, add 40-50 liters of water, and evenly spray on weeds. Stem leaves. For the prevention of perennial weeds, increase the amount to 100-150 ml.
310% quizalofop EC or 5% quizalofop EC. During the 3-5 leaf stage of weeds such as goosegrass, crabgrass, barnyardgrass, and maidenhair, 50-80 ml of 10% quizalofozil per mu, or 30-60 ml of 5% refined quizalofop was used. To prevent perennial grass weeds, increase the dose per mu to 100-130 ml.
412.5% ​​Flurpyridinium Chloride or 10.8% Flurpyridinium Chloride. During the 3-5 leaf stage of annual grass weeds, 12.5% ​​flupirazione or 10.8% flupirtine was used in 20-35 ml per mu.
536% Diflufenicin Emulsion When the annual grass-grass weeds are in the 2-4 leaf stage, 36-percent mucilage is used for 170-200 ml per mu. When spraying, the fog should be fine and spray as much as possible onto the weeds.
624% fufentrix ether. Annual broadleaf 2-4 leaf stage, with 25% fomesafen aqueous solution 67-100 ml per acre, add water 40-50 liters, evenly sprayed on weed stems and leaves. Adding 330 grams of urea can increase the weed control efficiency by 5%-10%. The safety of cowpea and edamame has no impact on the aftermath, but it has a certain impact on the live cabbage such as cabbage and vegetables and can be deep-drafted to reduce injury.
Herba pine can also be used as a selective post-emergence herbicide for broad bean, which is used during the 2-5 leaf stage of broadleaf. Use 48% of valerifolone 200ml?Mu +15% fluazifop 50-80ml (or 6.9% of oxazolyoxalin 50-90ml, or 10.8% of high-efficiency flupirtine 30ml) The formula to control single and dicotyledonous weeds has successful experience in soybeans, and can be used on the broad beans first.
