Abstract

The invention discloses a synergistic herbicidal composition for an uncultivated land and an orchard. The synergistic herbicidal composition consists of glufosinate and dicamba serving as active ingredients and acceptable auxiliary components in pesticides, wherein the weight ratio of the glufosinate to the dicamba is 1:3.2-10:1. After the two active ingredients are compounded, the synergistic herbicidal composition has the herbicide effect obviously superior to that of single glufosinate or single dicamba, has obvious synergism, can control perennial vines, undershrub weeds and broadleaf weeds and also can control annual and biennial weeds; and the herbicidal spectrum is enlarged, the use amount of single glufosinate and single dicamba is reduced, the production cost is reduced, and the herbicidal composition has obvious market popularization value.

Description

technical field [0001] The invention relates to a herbicide composition, in particular to a herbicide composition for non-arable land and orchard. Background technique [0002] Glufosinate-ammonium, also known as glufosinate, is a new type of organic phosphine herbicide, an inhibitor of glutamine synthesis, a non-selective broad-spectrum contact herbicide with partial systemic effect, chemical The structure is shown in formula (I), and it is mainly used in orchards, vineyards, non-cultivated land, potato fields, etc. to control annual and perennial dicotyledonous and gramineous weeds, such as sagegrass, crabgrass, barnyardgrass, wild barley, Multiflora ryegrass, foxtail, golden foxtail, wild wheat, wild corn, creeping wheatgrass, bentgrass, whiskgrass, sedge, bermudagrass, paspalum, awns, fescue, reed , bluegrass, amaranth, field chamomile, halberd-leaved agarina, shepherd's purse, quinoa, datura, canadian flying cape, medicinal cone violet, pepper grass, pig's weed, treasu...
