Abstract
The invention belongs to the technical field of agricultural agents, and discloses a mixed herbicide containing cinosulfuron, butachlor and cinmethylin and application thereof, wherein the herbicide takes the cinosulfuron, the butachlor and the cinmethylin as main active ingredients, and the mass ratio of the cinosulfuron, the butachlor and the cinmethylin is 0.1-80/0.1-80/0.1-80. The mixed herbicide is applied to weeding paddy field, and particularly has the obvious effect on the application in preventing and weeding weeds of various grass families, sedge families or broad leaves in the paddy field. Compared with a single herbicide, under the premise of improving the efficacy, the mixed herbicide also has the advantages of weakened herbicide resistance, wide weeding scope and long efficacy duration, and is safe to paddy and succeeding crops.
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, butachlor and cinmethylin.
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.
In recent years, along with increasing and the extensive popularization of chemical control technology in agricultural production of weed killer herbicide kind, chemical weed control has been widely used in each period of paddy growth.The choose reasonable weed killer herbicide not only can reduce friend peasant labour intensity, shorten working time, but also can reduce, cultivate cost, reach the purpose of volume increase.
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.
Butachlor (Butachlor), have another name called weed eradication spy, Machete, is the weed killer herbicide by the chloro-acetyl amine of Monsanto Company's exploitation, chemical name: N-(fourth oxygen methyl)-α-chloro-2 ', 6 '-diethyl acetanil.Its structural formula is as follows:
Butachlor is acetamide-group herbicides, mainly by weeds young shoot and immature secondary root, absorbs, and suppresses the body internal protein and generates, and makes the enlargement of weeds shoot, deformity, finally causes death.Only have a small amount of butachlor to be absorbed by rice seedling, and rapid fully katabolism in vivo, thereby rice seedling has larger drug-resistant capability to it.Butachlor stability in soil is little, stable to light, can be decomposed by edaphon, to second stubble crop safety.Be mainly used in transplanting, non-irrigated seedling rice field, effectively anti-divided by the grassy weed of seed germination, annual nutgrass flatsedge and some annual broadleaf weeds such as barnyard grass, moleplant seed, difformed galingale herb, cyperus iria, needle spikesedge herb etc.Monochoria vaginalis, Drilgrass, cusp flower and firefly Lin etc. are had to favorable effect, but nearly unavailable to perennial weeds such as water Rhizoma Sparganii, wild arrowheads.
Cinmethylin (cinmethylin), commodity cut by Chinese mugwort by name, by Shell Co. Ltd, Dupont development, the herbicide for paddy field of American Cyanamid Company (existing BASF AG) exploitation, chemical name: 1-methyl-4-(1-Methylethyl)-2-[(2-aminomethyl phenyl) methoxyl group]-7-evil two rings (2,2,1) heptane.Its structural formula is as follows:
Cinmethylin is processing soil treatment agent before selectivity inner sucting conduction type bud, can be by the root absorption of sensitive plant, and suppressing merismatic growth is plant death.Paddy rice, cotton, peanut etc. are strong to the drug-resistant capability of this medicine, enter and make in object to be metabolised to hydroxy derivatives, and be combined into conjugated compound and lose toxicity with the glucosides in plant corpus.In the no water layer situation, easily be evaporated and photodissociation, and can be decomposed by edaphon.Have in the water layer situation, decomposition rate slows down.Should be that main area is used annual weed, the lasting period be short, and the weeding optimal period is that weeds are in seedling or young tender phase, is mainly used in preventing and kill off barnyard grass, Monochoria vaginalis, arrowhead, firefly Lin, cyperus iria, difformed galingale herb etc.
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.
Summary of the invention
The mixed herbicide that the purpose of this invention is to provide a kind of cinosulfuron-containing, butachlor and cinmethylin.
Another object of the present invention is to provide the application of this weed killer herbicide.
