Abstract

The invention discloses a peanut field compound herbicide and a synthesis method thereof. The herbicide is prepared from, by weight, 15-25 parts of sodium dodecyl benzene sulfonate, 10-20 parts of clethodim, 5-12 parts of lactofen, 3-12 parts of pendimethalin, 10-20 parts of plant ash, 3-12 parts of oxyfluorfen, 1-8 parts of coptidis rhizome extract solution, 4-12 parts of merremia quinata extract solution, 3-8 parts of citric acid, 5-12 parts of acetochlor emulsifiable concentrate and 1-4 parts of chlorimuron-ethyl. The preparation process is simple, the prepared herbicide can effectively remove weeds in peanut fields and does not harm peanut leaves, and residues of the herbicide do not contaminate soil and the environment.

Description

technical field [0001] The invention relates to the technical field of herbicide preparation, in particular to a compound herbicide for peanut fields and a synthesis method thereof. Background technique [0002] Peanut, formerly known as groundnut, belongs to Rosaceae, annual herbaceous plant of Fabaceae, stem erect or prostrate, 30-80 cm long, wing petals and keel petals separated, pods 2-5 cm long, 1-1.3 cm wide, swollen, thick pods , the flowering and fruiting period is June-August. Mainly distributed in Brazil, China, Egypt and other places. Annual herb. Roots have abundant nodules; stems are erect or prostrate, 30-80 cm long, stems and branches are ribbed, covered with yellow villous hairs, then become glabrous. Leaves usually have 2 pairs of leaflets; stipules 2-4 cm long, with longitudinal veins, hairy; base of petiole clasping, 5-10 cm long, hairy; leaflets papery, ovate-oblong to obovate, long 2-4 cm, 0.5-2 cm wide, apex obtusely rounded, sometimes slightly conc...
