Technical Field

The invention relates to a herbicide composition for farmland weeds, in particular to a herbicide composition containing quizalofop-p-ethyl and flumetsulam and a preparation method thereof.

Background

In recent years, with the increasing demand for development of new compounds for agricultural chemicals, while complying with the policies of high selectivity, high safety and high efficacy, it is necessary to save the cost of the drug, and in this case, the existing compounds are used in a rational combination. Thereby achieving the purpose of solving the problem.

Quizalofop-p-ethyl, other names: secale grass, NC-302D (+). The molecular formula is C19H17ClN2O4, and the chemical name is as follows: (R) -2- [4- (6-chloroquinoxalin-2-yloxy) phenoxy ] propionic acid ethyl ester. The quizalofop-p-ethyl is absorbed by the stem leaves of the weeds, is conducted in the plant body in two directions upwards and downwards, is accumulated on the top and the intermediate meristem, inhibits the synthesis of cell fatty acid and necrotizes the weeds. Quizalofop-p-ethyl is a novel high-selectivity stem and leaf treating agent for dry farmland, has high selectivity between gramineous weeds and dicotyledonous crops, and has good control effect on gramineous weeds in broad leaf crop fields. Has faster action speed and more stable drug effect, and is not easily influenced by environmental conditions such as temperature, humidity and the like of rainwater. The fertilizer is suitable for various crops such as soybean, beet, rape, potato, flax, pea, broad bean, tobacco, watermelon, cotton, peanut, broad-leaved vegetable and the like, fruit trees, forestry nursery gardens, young forest nurturing, alfalfa and the like. Quizalofop-p-ethyl is a universal herbicide and can be used after Chinese medicinal materials grow true leaves. Can be used for preventing and treating annual and perennial grass weeds such as wild oat, barnyard grass, green bristlegrass, meadowrue, broomcorn grass, aloesweed, teff grass, moleplant seed, brometum, barley, lolium multiflorum, toxylum, millet, bluegrass, paspalum distichum, bermudagra grass, cogongrass, creeping wheatgrass, reed and the like.

Flumetsulam, other names: flumetsulam, broadleaf holly leaf. The molecular formula is C12H9F2N5O2S, and the chemical name is as follows: n- (2, 6-difluorophenyl) -5-methyl-1, 2, 4-triazolo [1,5-a ] pyrimidine-2-sulfonamide; 2',6' -difluoro-5-methyl (1,2,4) -triazolo (1,5-a) pyrimidine-2-sulfonanilide. Flumetsulam, a triazolopyrimidine sulfonamide, is a typical acetolactate synthase inhibitor. By inhibiting the synthesis of branched chain amino acids, protein synthesis is hindered and the plant stops growing. Long residual effect period, broad weed-killing spectrum, and can be used for treating soil, stem and leaf. The flumetsulam is suitable for preventing and treating 1-year and perennial broadleaf weeds such as field horsetail (herba abri), shepherd's purse, small flower sugar mustard, striga asiatica, descurainia (artemisia sieboldii), polygonum, speedwell (catkin), cocklebur (field fruit), black nightshade (wild grape), amaranth (amaranth), chenopodium album (chenopodium album), abutilon (hemp fruit), cleavers (cleavers and taraxacum), and tourbillon. It also has certain inhibiting effect on young gramineous weeds.

The existing herbicide composition is limited in control objects, low in pesticide effect and high in weeding cost.
