Soybean is an important food crop and oil crop in China, and the planting area has also been expanding. The elimination of weeds is conducive to improving the quality of soybeans. There are many varieties of herbicides, and it is necessary to raise the awareness of farmers' friends about herbicides, so as to increase income and increase production. China Pesticide Network Xiaobian specifically introduces you to soybean field herbicide varieties:
Soybean field pre-emergence safety herbicides are fast-receiving, chlorhexidine, dol (metolachlor), Pulebao (isomethasamine), Lefengbao, broad-grass clear, Baoshou (broadleaf)æ•£), Pu Shite.
Inhibition of soybean seedlings is 24 drops of butyl ester, 50% acetochlor, trifluralin, peacaprol (chlorsulfuron), syke, oxazin (oxazinone). Bean huanglong application period is short, and the safety of soybean and post-production is poor. It should be eliminated; trifluralin has inhibitory effect on soybean root growth, the disease is aggravated, the nodule is less and the yield is reduced, and the use of trifluralin for a long time is serious. Should be eliminated; 24-d-butyl ester is limited to pre-emergence or post-emergence with 50% acetochlor per acre. Soybean is less safe than 90% acetochlor and 90% Wones, pesticide manufacturers recommend, quickly use Duer High-content acetochlor is replaced by Plexus, Lefengbao or 90% Wones or 90% acetochlor, 90% Shengong Shi. Sec, alaprozin (oxazinone), sensitive to individual soybean varieties, known Hefeng 25, Jiufeng 4 and Beifeng series varieties, in the low-lying low-rain conditions, or in the soybean arching period In particular, the combination of acetochlor and acetochlor aggravation has a great impact on the yield. Soybean field soil phytotoxicity is more serious and should be restricted to use in hills, arid areas and autumn application. After the fast-distribution, the seedlings should be shallowly mixed or soiled 2 cm after application. At present, broadleaf weeds and refractory weeds in soybean fields are serious, and herbicides should be developed from two mixed uses to three mixed uses. The following formulations are recommended for reference.
Duer or Pulebao (Le Fengbao) Jiaguang annihilation accelerated or Bao Bao or Kucaoqing, Duer or Pulebao (Le Fengbao) accelerate the collection of Baobao or Kucaoqing, Henas or 90% Shengnong Shi (acetochlor) is widely used to accelerate the harvest or treasure book or broad grass clear. Or Pulebao (Le Fengbao) accelerates the harvest or Baoshou or Guangshenling or Kushuiqing, He Naisi or 90% Shengnong Shi (acetochlor) accelerates or collects or Guangling or broad grass clear . The pesticide network suggests that Pusto Ghad, Pulebao (Le Fengbao), Henas, Shengnong Shi, etc. can be used in the soybean, corn and wheat rotation areas.
