Abstract
The invention belongs to the technical field of pesticides, and discloses a mixed herbicide, particularly a mixed herbicide containing cinosulfuron, bispyribac-sodium and cyhalofop-butyl and application thereof. The herbicide adopts the cinosulfuron, the bispyribac-sodium and the cyhalofop-butyl as main active components, the weight ratio of which is 0.1 to 80:0.1 to 80:0.1 to 80. The mixed herbicide is applied in the weeding of paddy fields, and particularly has a remarkable effect in preventing and getting rid of various gramineous, cyperaceous and broadleaf weeds in paddy fields. Compared with single agents, the herbicide delays the resistance of weeds under the premise that the effect is enhanced, has a broad weeding spectrum and long persistence, and is safe for rice 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, two careless ether and cyhalofop-butyl.
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, pondweed, arrowhead, Monochoria vaginalis, invalid to barnyard grass and moleplant seed etc.
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, two (4, the 6-SDM base-2-oxygen base) Sodium Benzoates of chemical name: 2,6-.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.
Cyhalofop-butyl (Cyhalofop-butyl), commodity are called a thousand pieces of gold, the phenoxy carboxylic acid herbicides of LG-DOW agricultural science company exploitation, chemical name: (R)-2-[4 (4-cyano group-2-fluorophenoxy) phenoxy group]-butyl propionate, its structural formula is as follows:
Cyhalofop-butyl is unique kind that paddy rice is had to tight security in aryloxyphenoxypropanoates class weed killer herbicide, the same with such other kinds, is also inner-adsorption conduction-type herbicide.Cyhalofop-butyl is absorbed by leaf sheath and the blade of plant corpus, the phloem conduction, accumulate the meristem zone in plant corpus, suppress acetyl-CoA carboxylase (ACCase), fatty acid is synthesized to be stopped, the growth division of cell can not normally be carried out, and film system etc. contains membrane structure to be destroyed, and finally causes plant death.From cyhalofop-butyl, be absorbed into the weeds Mortality Ratio slower, generally need 1-3 week.The symptom of weeds after dispenser is as follows: the tender shoots atrophy of four leaf phases, finally work hard lethal.The leaf rapidly of growing tri-leaf period stops growing after a couple of days, the how many appearance of limb edge are sallow, cause death.The Lao Ye of two leaf stage changes minimum, keeps green.Cyhalofop-butyl can be degraded to rapidly the diacid state to the acetyl-CoA carboxylase non-activity by paddy rice, thereby paddy rice is had to the safety of height.In soil and in typical paddy field water either, degraded is rapid because of it, therefore to succession crop safety.Be mainly used in preventing and kill off grassy weed.Cyhalofop-butyl is not only efficient to various barnyard grasses (comprising above the average age for marriage barnyard grass), also can prevent and kill off moleplant seed, lady's-grass, Paspalum distichum, green foxtail, eleusine indica, amur foxtail etc.Invalid to sedge family and broad leaved weed.
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.
