目前,玉米田化学除草多采用莠去津(阿特拉津)与拉索或杜耳混合配方,在玉米播后苗前施用药效较好.但是,如果遇到春旱,除草效果往往不够理想,为了解决这个问题,我们(?)了多年研究,认为玉米田苗后化学除草配用增效剂较好.具体使用方法是每亩用40%.莠去津胶悬剂200克,对水40公斤,混匀后再加入“除草增效剂1号”100克,充分搅拌,在玉米3—5叶期、单子叶杂草4叶期前施用.玉米田除草应用除草增效剂省工省力省药,省资金,减轻土壤残留,并有壮苗增产的作用.其主要优点是:①使用“除草增效剂1号”与莠去津配制,可减去拉索和杜耳的用量,降低用药成本,每亩节省3—4元.②加入增效剂可增加杀草效果,尤其增加了防治草子叶杂
At present, the chemical herbicide in corn field mostly uses the combination of atrazine (atrazine) and basso or dulcox, and the effect of pre-emergent application in corn is better, however, the herbicidal effect is often not enough in the spring drought Ideal, in order to solve this problem, we (?) Years of research, that post-emergence maize chemical weeding with synergist is better. Specific use is 40% per acre. Atrazine 200 grams of suspension, water 40 kg, mix, then add “weed synergist No. 1” 100 grams, stir, corn 3-5 leaf stage, monocotyledon weed 4 leaves before the application of weed herbicides synergist workers Labor-saving provincial medicine, provincial funds to reduce soil residues, and strong seedling production. Its main advantages are: ① the use of “weed synergist No. 1” and atrazine formulation can be deducted from the amount of cable and Duer , Reduce the cost of medication, saving 3-4 yuan per mu.② Add synergist can increase the herbicidal effect, in particular, increased the prevention and treatment of grass-leaf hybrid
