What herbicides are suitable for use during the celery growing period?
Celery grown by conventional methods has a high fiber content, and often because of imprecise management or delayed harvesting, the stalks are rather hard, which affects its commercial value and can even make it unfit to eat. Based on the successful experience of some vegetable growers over many years, adopting a set of celery tenderizing cultivation methods not only reduces the fiber content of the stalks but also improves their eating quality and...
There are many suitable herbicides for controlling grass weeds during the celery growing period. You can choose herbicides such as quizalofop-p-ethyl, haloxyfop-R-methyl (haloxyfop-R-methyl), clethodim, and fenoxaprop-P-ethyl. Generally, the herbicide should be applied when the weeds have basically all emerged and are at the 3-5 leaf stage. Per mu, choose 40-60 ml of 5% quizalofop-p-ethyl emulsifiable concentrate, or 25-40 ml of 10.8% haloxyfop-R-methyl emulsifiable concentrate, or 35-40 ml of 12% clethodim emulsifiable concentrate, or 50-60 ml of 6.9% fenoxaprop-P-ethyl concentrated emulsion, add 30-40 kg of water and spray. When the weeds are older, appropriately increase the dosage. Broadleaf weeds in the field during the celery growing period are relatively difficult to control with herbicides, so it is better to use soil sealing treatment before transplanting or after sowing and before emergence to control weed occurrence. Suitable herbicides include oxadiazon, oxyfluorfen (Goal), and butralin, among others. Among them, oxyfluorfen and oxadiazon have good control effects on many broadleaf weeds and some seed-propagated sedges. In transplanted fields, herbicides such as dimethylamine salt, trifluralin, and metolachlor (Dual) can also be used before transplanting. Per mu, you can use 100-150 ml of 33% pendimethalin emulsifiable concentrate (Stomp), or 100-150 ml of 48% trifluralin emulsifiable concentrate, or 125-150 ml of 25% oxadiazon emulsifiable concentrate, or 100 ml of 72% metolachlor emulsifiable concentrate, add 40-50 kg of water and spray.
