Soybean field herbicide

Abstract

The invention discloses a soybean field herbicide. The soybean field herbicide is prepared from the following raw materials in parts by weight: 2 to 4 parts of pendimethalin, 4 to 6 parts of cyhalofop-butyl, 8 to 10 parts of quizalofop-p-ethyl, 5 to 7 parts of acetochlor, 5 to 7 parts of chlorimuron-methyl, 5 to 7 parts of radix euphorbiae lantu, 1 to 3 parts of dimethazon, 3 to 5 parts of acetochlor, 2 to 4 parts of quinclorac and 60 to 80 parts of water. A preparation method is simple and environment-friendly; the soybean field herbicide has a good weeding effect, a wide weeding spectrum, low use amount and small pollution.

Description

technical field [0001] The invention relates to the technical field of crop herbicides, in particular to a soybean field herbicide. Background technique [0002] Soybeans are commonly known as soybeans. Fabaceae soybean is an annual herb, 30-90 cm high. The stem is stout, erect, densely covered with brown long bristles. Leaves usually have 3 leaflets; stipules are veined and yellow pilose; petiole is 2-20 cm long; leaflets are broadly ovate and papery; racemes are short and few-flowered, long and multi-flowered; total pedicel usually has 5 -8 sessile, tightly packed flowers; bracts lanceolate, strigillose; bracteoles lanceolate, appressed setae; calyx lanceolate, flowers purple, lilac or white, base petalized Stem, petals castrate. The pods are hypertrophic, slightly curved, drooping, yellow-green, densely covered with brown-yellow long hairs; 2-5 seeds, oval, nearly spherical, with smooth testa, various in light green, yellow, brown and black. The flowering period is f...

Problems solved by technology

The flowering period is from June to July, and the fruiting period is from July to September. Soybean is often harmed by various weeds from sowing to harvest. Due to the influence of climate and soil quality, the types and numbers of weeds vary from region to region. It is the most effective method to remove weeds in wheat fields. At present, the main herbicides for weed control in soybean fields are mostly one or two effective herbicides. Due to long-term use, the resistance increases, resulting in a large dosage, environmental pollution, and also Increased farmers' pesticide application costs, in order to solve the above-mentioned drawbacks, the present invention selected several new drug components with control and weed control effects, and developed a soybean field herbicide and its preparation method, which can absorb safeners and thus are not affected by herbicides. The influence of the active ingredients, and weed seeds absorb herbicides when they germinate, but at this time weeds do not have roots and cannot absorb safeners, so they are killed by the active ingredients of herbicides. Adding safeners to herbicides can Soybeans are protected from harm while weeds are effectively eradicated
