Weed herbicide

Abstract

A weed herbicide is prepared by the following raw materials by weight parts: 9.5 % of fomesafen, 2.5 % of quizalofop p ethyl, 23 % of clomazone, 42 % of 1,1'-dimethyl 4,4'-dichloro bipyridine, and 40 % of glyphosin. The weed herbicide can control various annual weeds, is strong in killing effect on perennial weeds, while underground stems and roots of the perennial weeds can sprout new branches, and has no influence on lignified brown stems and trunks. The weed herbicide is suitable for controlling weeds in orchards, mulberry gardens, rubber plantations and forests, as well as weeds at non-cultivated lands, ridges and road sides, and can control weeds for corns, sugarcanes, soybeans, nursery gardens and other wide-row crops by directed sprays. The weed herbicide can be further used as an auxiliary medicament used after a defoliant for machine harvested crops. For an ideal defoliating effect is not achieved when a harvesting stage is approaching after the crops are applied with the defoliant, the weed herbicide can be used to rapidly kill green tissues of the crops, dehydrate and dry the green tissues, and do not influence short-period stacking and transporting of the harvested fruits after a mechanical harvesting.

Description

technical field [0001] The invention belongs to the technical field of herbicides, and in particular relates to a weed herbicide. Background technique [0002] Weeds are generally resistant to herbicides. According to reports, about 45 million acres of land in the world have drug-resistant weeds. In Japanese orchards, tea gardens, and mulberry fields, paraquat has been applied for more than 5-6 years, and some weeds have developed resistance. Contents of the invention [0003] The present invention aims to solve the problem of the widespread resistance of weeds to herbicides. [0004] The present invention is achieved through the following technical solutions: [0005] A weed herbicide, characterized in that: it is prepared according to the following weight ratio of raw materials, 9.5% of aminofenac, 2.5% of quizalofop-p-ethyl, 23% of clomazone, 1,1' dimethyl 4,4 'Dichlorodipyridine 42%, glyphosate 40%. [0006] Compared with the prior art, the present invention has th...
