Pre-emergence herbicide mixture applied to peanut field

Abstract

The invention relates to a herbicide composition and in particular relates to a pre-emergence herbicide mixture applied to a peanut field. The composition is prepared from the following raw materials in parts by weight: 30-45 parts of lactofen, 30-45 parts of acifluorfen, 14-23 parts of pendimethalin, 14-22 parts of metolachlor and 8-10 parts of s-metolachlor. The herbicide composition is used for weeding by different manners; different tissue parts of weeds are used as absorption paths; the herbicide composition respectively takes effect on different target enzymes of the weeds by synthetic action of touching and killing, internally adsorbing and transmitting; the weeds can be removed at one time; the succession of weed communities and the herbicide resistance enhancement can be effectively avoided; the pollution to the environment and the threat on the crops and foods can be alleviated.

Description

technical field [0001] The invention relates to a herbicide composition, in particular to a pre-emergence herbicide mixture for peanut fields. Background technique [0002] Peanut, formerly known as groundnut (scientific name: Arachis hypogaea Linn.), belongs to Rosaceae, leguminous annual herb, stem erect or prostrate, 30-80 cm long, wing petals and keel petals are separated, pods are 2-5 cm long and 1.5 cm wide. -1.3 cm, swelling, thick pods, flowering and fruiting period from June to August. Mainly distributed in Brazil, China, Egypt and other places. [0003] 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, somet...

Problems solved by technology

[0005] And usually peanut field herbicides all have strong selectivity, the weeding effect is good to a certain family weeds but the weeding effect is very poor to another family weeds, so can only use multiple times, multi-variety, multi-dose, exceed The amount and abuse of pesticides have brought negative impacts such as rice quality decline and environmental pollution, and increased the cost of pesticides.
