Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of weed killer herbicide, be specifically related to mixed herbicide and the application thereof of a kind of cinosulfuron-containing, Acetochlor and two careless ethers.
Background technology
China is the country with the longest history of rice cropping in the world, and paddy rice is one of China's staple food crop, and approximately 3,300 ten thousand hectares of cultivated areas, account for 29% of plant of grain crops area.
Not weeding of field it is reported that annual national paddy rice all is subject to crop smothering in various degree, if can make the paddy rice underproduction more than 50%.Weeds have the paddy field main harm: barnyard grass, moleplant seed, reed, firefly Lin, Herba Cyperi Glomerati, difformed galingale herb, cyperus iria, miliary fimbristylis herb, pondweed, Eclipta prostrata, wild arrowhead, Monochoria vaginalis etc.The economic loss caused in order to reduce crop smothering, reduce labor intensity, and also because chemical weed control is convenient, quick-acting, the control time is long, chemical weed control is accepted by people gradually simultaneously.

Cinosulfuron (Cinosulfuron), have another name called the first cinosulfuron, a kind of sulfonylurea herbicide, formal name used at school 1-(4,6-dimethoxy-1,3,5-triazines-2-yl)-3-[2-(2-methoxy ethoxy) phenyl sulphonyl] urea, its structural formula is as follows:
Cinosulfuron mainly absorbs by root and stem, is sent to meristematic tissue by conducting tissue, suppresses the biosynthesis of branched-chain amino acid (as serine, isoleucine).After medication, weeds can be not dead immediately, but stop growing, and after 5-10 days, plant starts yellow, withered death.In the paddy rice body, active ingredient can be by urea bridge fracture, after methoxyl group hydrolysis, deamination and phenyl ring hydrolysis and the sucrose yoke approach such as close, finally be metabolized to non-poisonous material, half life period is less than 1 day in rice root, and the half life period is 3 days in the paddy rice leaf, so to rice safety.But, due to its water-soluble large (3.7g/L water), in water leaking paddy field, thereby may focus on the rice root district with water, paddy rice is caused to poisoning.For dry sowing, water, broadcast annual broadleaf weed and the sedge weeds such as rice field control rhizoma alismatis, nutgrass flatsedge, apple, pondweed, arrowhead, Monochoria vaginalis, invalid to barnyard grass and moleplant seed etc.
Acetochlor (acetochlor), commodity standing grain by name anti-this, be the chloro-acetyl amine weed killer herbicide by the exploitation of Monsanto company, chemical name: 2 '-ethyl-6 '-methyl-N-(ethoxymethyl)-2-chloro acetanilide, its structural formula is as follows:
Acetochlor is the selectivity preemergence herbicide.Can be absorbed by plant plumule, monocotyledon absorbs by bud scale, dicotyledon hypocotyl Assimilation and conductivity, must dispenser before weeds are unearthed, active ingredient RNA metabolism and protein in plant corpus is synthetic, and young shoot, young root are stopped growing, if moisture suitable young shoot in field is unearthed and namely is killed, if soil moisture is few, after weeds are unearthed, with soil moisture, increase after weeds absorb medicament and work, the curling atrophy of grassy weed performance lobus cardiacus, other leaf shrinkage, whole strain is withered.Acetochlor is high to grassy weed activity such as lady's-grass, the Amaranthus retroflexus sensitivity, the broadleaf weeds such as lamb's-quarters, kitchen garden, black nightshade there is is certain preventive effect and suppress growth, the specific activity grassy weed is low, Soybean Dodder is had to good preventive effect, the drug resistance Crop Acetochlors such as soybean are the non-activity material in the rapid metabolism of body, normally use crop safety.Mainly prevent and kill off barnyard grass and part broad leaved weed.
Two careless ethers (bispyribac-sodium), have another name called the salicylic acid Sulfadiazine Compound, is the pyrimidine Type salicylic acid broad-spectrum herbicide by the exploitation of Japanese combinatorial chemistry company, chemical name: 2, two (4, the 6-SDM base-2-oxygen base) Sodium Benzoates of 6-, its structural formula is as follows:
Two careless ether is highly active ALS inhibitor, by the biosynthesis that hinders branched-chain amino acid, work, mainly the direct Tanaka of paddy rice, use, prevent and kill off grassy weed, can prevent and kill off the barnyard grass of 1～7 leaf phase especially, double most of broad leaved weeds, some sedge weeds and the Stam F-34 controlled produces the resistance barnyard grass, and consumption is extremely low, has broad application prospects.
Herbicide for paddy field is limit by crop safety at present, the herbicide spectrum is also limited, use separately a kind of weed killer herbicide single dose can not control completely effectively the generation of paddy field weed, moreover some weed killer herbicide is due to water-soluble large or the field lasting period is oversize, consumption is excessive or dispenser is inhomogeneous all easily causes the residual hazard to this season crop or succession crop.
