Abstract
The invention discloses a rimsulfuron.haloxyfop-P-methyl water dispersible granule as a weed killer and a preparation method thereof, belonging to the technical field of weeding for plant protection. The rimsulfuron.haloxyfop-P-methyl water dispersible granule comprises the following components in percentage by mass: 10-20% of rimsulfuron, 5-10% of haloxyfop-P-methyl, 3-5% of wetting agent K12, 5-8% of ketamine as a dispersing agent, 5-7% of ammonium sulfate as a disintegrating agent, 5-10% of white carbon black as a carrier and the balance of light calcium carbonate as packing. The rimsulfuron.haloxyfop-P-methyl water dispersible granule can be used for preventing and controlling grassy weeds such as crab grass, moleplant seeds, annual broad-leaved weeds such as crowndaisy chrysanthemum, piemarker and the like and cyperaceae weeds such as cyperus rotundus and the like in a tobacco field. The rimsulfuron.haloxyfop-P-methyl water dispersible granule has the advantages of no need of specific equipment for a process, simplicity in operation, low preparation cost, little pollution to the environment, safety in storage and transportation, stable preventing effect and the like.
Description
Technical field
The present invention relates to a kind of weed killer herbicide, particularly relate to composite water dispersible granules of a kind of rimsulfuron and efficient haloxyfop-methyl spirit and preparation method thereof.
Background technology
Along with the enhancing of human environment protection consciousness, water base property, formulation granular, multi-functional, laborsaving, the safety and health low environmental impact become the developing direction of the domestic and international formulations of pesticide.The solid formulation granulating is meant with water dispersible granules, effervescent tablet etc. and replaces pulvis or wettable powder.Water baseization of liquid formulation is meant with water to be that medium prepares the formulations of pesticide, like aqueous emulsion, and microemulsion, aqueous suspension agent.
Pesticide water dispersible granules is good because of its safety, and environmental pollution is little, has the advantage of traditional formulations of pesticide, is considered to an important directions of formulations of pesticide development.Water dispersible granules is a kind of granular preparation that adds behind the water disintegration rapidly and disperse to form suspension, mainly is made up of active ingredient, wetting agent, dispersible granule, carrier and disintegrant.
English common name: the rimsulfuron of rimsulfuron; Other title: rimsulfuron 25; It is the sulfonylurea weed killer herbicide of du pont company exploitation; It is acetolactate synthestase (ALS) inhibitor; Through suppressing the acetolactate synthestase in the plant corpus, stop the biosynthesis of branched-chain amino acid, thereby suppress cell division; Responsive grass family and broad leaved weed are stopped growing, and chlorisis, spot are withered until complete stool death then.Rimsulfuron is a selective herbicide, also is transported to meristematic tissue fast by root and the absorption of leaf portion.Rimsulfuron is a kind of sulfonylurea post-emergence herbicide, and annual and perennial grassy weed and some broad leaved weed in the major control corn field also are used for potato, tomato and tobacco, and general consumption is 15g/hm
2In most cases as far as most of crop, rimsulfuron is safe.
The efficient haloxyfop-methyl spirit is a benzene oxygen carboxylic class weed killer herbicide, is the fatty acid synthetic inhibitor, English general haloxyfop-R-methyl by name, and trade name has smart cover grass energy, haloxyfop-r-methyl etc.Be applicable to the broad leaf crop field; Can prevent and kill off annual and perennial grassy weeds such as lady's-grass, barnyard grass grass, Bermuda grass, yard grass; Also can be used as the weeding in nursery, absorbed by the leaf of grass family class grass very soon after cauline leaf is handled and conduct to whole plant, suppress the plant meristematic tissue and kill dogstail.The medicament of unrestrained soil is prone to be absorbed, and also can play and kill grass effect, average 55 days of half life period in soil.The efficient haloxyfop-methyl spirit is to plant height safety, and to nearly all broad leaf crop safety, the several times that surpass positive usual amounts can not produce poisoning yet.The efficient haloxyfop-methyl spirit absorbs rapidly, and rainfall in 1 hour does not influence drug effect after the dispenser; Lasting period is long, but the harm of the grassy weed in dispenser basic controlling time of infertility can reduce peasant's labour intensity greatly.
Up to the present, the correlative study report that does not still have efficient haloxyfop-methyl spirit and the composite water dispersible granules of rimsulfuron.
Summary of the invention
The object of the present invention is to provide a kind of rimsulfuron efficient haloxyfop-methyl Lingshui Spring dispersible granule.Synergy with reference to People's Republic of China's agricultural industry criteria-weed killer herbicide is mixed is measured; The grass spectrum of killing according to rimsulfuron and the single agent of efficient haloxyfop-methyl spirit is selected representative weeds; The employing cauline leaf is handled, and estimates two kinds of medicaments to the synergy type of weeds and the reasonability of proportioning through the Gowing method.Obtain described rimsulfuron efficient haloxyfop-methyl Lingshui Spring dispersible granule, the quality percentage composition of its component and each component is following:
Rimsulfuron 10 ~ 20%
Efficient haloxyfop-methyl spirit 5 ~ 10%
Wetting agent K12 3 ~ 5%
Dispersant K powder 5 ~ 8%
Disintegrant ammonium sulfate 5 ~ 7%
Carrier white carbon 5 ~ 10%
The filler precipitated calcium carbonate supplies 100%
K12 is a neopelex, is agricultural chemicals usual auxiliaries, wetting agent.
The K powder is a common dispersants.
Further, the best proportioning of rimsulfuron and efficient haloxyfop-methyl spirit is mass ratio 2:1.
The preparation method of rimsulfuron efficient haloxyfop-methyl Lingshui Spring dispersible granule of the present invention is following:
By said each constituent mass ratio, with the spirit of white carbon absorption efficient haloxyfop-methyl, add the former medicine of rimsulfuron and other auxiliary agents then earlier; After the pulverizing of high speed Universalpulverizer, add the water-wet of quality of material 17%, stir then; Granulation in Squeezinggranulator; Particle diameter 1-2mm, granulation is placed in 54 ℃ of baking ovens dried by the fire 1-2 hour, obtained rimsulfuron efficient haloxyfop-methyl Lingshui Spring dispersible granule product.
Advantage of the present invention:
(1) formulation is advanced, for environmentally friendly green formulation, need not organic solvent in process of production, has reduced the pollution to environment, and to operator's safety, storage stability is good, and the product low toxicity has improved safety.
(2) preventive effect is stable, and grass is general wide extremely, and a dispenser can be prevented and kill off the multiple broad leaved weed in tobacco field, grassy weed, sedge weed.Rimsulfuron and efficient haloxyfop-methyl spirit are composite, and the synergy type is a summation action.
(3) preparation technology is simple, need not special installation, is easy to promote.
