Herbicide is suitable for celery growing period

There are many suitable drugs to control Gramineae weeds during the growing period of celery, such as quinofop, high-efficiency fluoropyramine (high-efficiency cover grass energy), alkenone, oxazolyl and so on. Generally speaking, the herbicide should be applied when the weeds are basically full of weeds and are in the 3-5 leaf stage. Choose 5% quizalofop EC 40-60 ml per mu, or 10.8% high-efficiency fluoropyrin EC 25-40 ml, or 12% envalerone EC 35-40 ml, or 6.9% oxazolidin concentrated EC 50-60 ml, add 30-40 kg water spray, and appropriately increase the dosage when the grass age is older. During the growing period of celery, it is difficult to control broad-leaved weeds in the field. Soil closure treatment should be used to control the occurrence of weeds before transplanting or before sowing, such as oxadione, ethoxyfluoxane (Gor), Zhong Dingling and so on. Among them, ethoxyflurane and oxazone have better control effects on many kinds of broad-leaved weeds and some sedge propagated by seeds. Transplanting fields can also use dimethylformalin, trifluralin, Metolachlor (dur) and other drugs before transplanting. You can use 33% pendimethalin EC 100-150 ml per mu, or 48% trifluralin EC 100-150 ml, or 25% oxazone EC 125-150 ml, 72% Metolachlor EC 100 ml, plus 40-50 kg water spray.
