Description

A kind of herbicide granule containing pretilachlor, pyraclonil and mesotrione
Technical field
The present invention relates to a kind of herbicide granule containing pretilachlor, pyraclonil and mesotrione, more particularly to specific It is related to a kind of herbicide for being used to prevent and treat transplanting rice field annual grassy weeds and barnyard grass.
Background technology
Pretilachlor is the rice terrace herbicides special for having high selectivity.English common name：pretilachlor.Other names Claim：Sweep Fu Te (Sofit).Chemical name：The chloro- N- of 2- (1- methyl -2- methoxyethyls)-N- (2- ethyl -6- aminomethyl phenyls) second Acid amides.Pretilachlor is the rice terrace herbicides special for having high selectivity.To rice safety, broad weed-killing spectrum.Weed seed is being sent out Medicament is absorbed during bud, root absorption is poor.Soil treatment before bud can only be made.
Pyraclonil is rice terrace herbicide, be German Schilling company (being now Beyer Co., Ltd) find there is pyrazolo The novel structure compound of pyridine ring, applied for a patent (WO9408999) on October 12nd, 1992.It occurs to barnyard grass and simultaneously Annual Ju Mang cyperus irias section firefly Lin, needle spikesedge herb, broad leaved weed Chinese herbaceous peony shape Monochoria korsakowii, Procumbent Falsepimpernel and for many years wild kind The wide scope weeds such as mushroom, water chestnut have very high activity.
Mesotrione is that one kind can suppress before the bud of medical midbodies of para (ortho)-hydroxybenzoic acetone acid esters dual oxide enzyme (HPPD) and after seedling wide spectrum Selective herbicide, it can effectively prevent and treat main broadleaved herb and some grassy weeds.
In actual use, when pyraclonil, pretilachlor and pyrazosulfuron are used alone, to the naked of transplanting rice field The drug effect of flower triquetrousc murdannia herb, moleplant seed, lady's-grass, eleusine indica etc. is not very notable.Therefore, inventor by pyraclonil, third grass Amine and pyrazosulfuron carry out rational mixture, while the triacontanol of paddy growth, the raw material of Brodifacoum will be aided in add In the composition for entering pyraclonil, pretilachlor and pyrazosulfuron, find that there are all kinds of weeds in transplanting rice field and significantly prevent and kill off Effect, while the growth of transplanting rice is also remarkably reinforced.
The content of the invention
It is an object of the invention to provide a kind of herbicide granule containing pretilachlor, pyraclonil and mesotrione, so that Production is made that a kind of component is reasonable, and herbicidal spectrum is wide, and preventive effect is good, and drug cost is low, be not likely to produce it is drug-fast it is a kind of containing pretilachlor, The herbicide granule granular preparation of pyraclonil and mesotrione.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions：
The present invention is a kind of herbicide granule containing pretilachlor, pyraclonil and mesotrione, including following weight accounting Raw material components：
It is pretilachlor 10%-20%, pyraclonil 5%-10%, mesotrione 40%-45%, triacontanol 2%-5%, right Chlorophenoxyacetic acid sodium 0.2%-2%, remaining is insecticides adjuvant.
The insecticides adjuvant of herbicide granule agent containing pretilachlor, penoxsuam and halosulfuronmethyl includes following raw material： Auxiliary agent carrier：Ammonium sulfate, urea, potassium dihydrogen phosphate, calcium superphosphate, diatomite, white carbon；Binding agent：Paraffin, polyvinyl pyrrole Alkanone, hydroxypropyl methyl cellulose, PVP, polyacrylamide, polyvinyl alcohol；Coloring agent：Iron oxide.
Further, including the preparation to triacontanol：Rice bran vinegar is subjected to refinement treatment, and soap is carried out with sodium hydroxide Change, after being extracted using acetone, then carry out filtering with clear water and refine, by vacuum topping, obtain crystallizing sterling；
Preparation including Brodifacoum：Chlorophenol is transported in condensation reaction pot, is heated to 50-55 degree, is melted After sodium hydroxide solution is added dropwise, and be sufficiently stirred, continue insulation reaction 30-40min after the completion of stirring, then use 95-98 Degree hot water is diluted dissolving, and it is 1 that hydrochloric acid is added dropwise into solution and is acidified to pH value, carries out crystallization operation, obtains to chlorobenzene oxygen second Acid；Again by p-chlorophenoxyacetic acid and liquid caustic soda effect generation salt, concentration crystallization, suction filtration, washing, dry after obtain p-chlorophenoxyacetic acid Sodium.
Further, including the preparation technology flow to herbicide granule：
The first step, pretilachlor, pyraclonil and mesotrione three are poured into agitator according to the ratio set, added Enter a certain amount of water, be stirred, triacontanol is added in stirring；
Second step, the mixture in the first step is delivered in refinery pit, is diluted with water 45%-55%, is put into chlorine Sodiumphenoxyacetate, and continue stirring operation；
3rd step, the turbid solution of second step is sent into evaporator tank, insecticides adjuvant is added in turbid solution, fully stirred It is evaporated under reduced pressure after mixing, rise temperature to 70-80 degree, when solid eduction rate reaches 65-75, stops evaporation operation；
4th step, reagent slurry made of the 3rd step is delivered in particle extrusion cabin, completes wet after particle extruding Grain is delivered to dryness storehouse, drying is aerated, by the water content control of granular preparation within 2%；
5th step, the granular preparation that the 4th step is completed is delivered in vibrating screen device, caking, the preparation granules warp of adhesion Vibratory sieve is separated, and obtains the preparation granules of uniform-dimension.
Further, the herbicide granule being prepared is water-soluble granular, wine soluble particles or organic solvent dissolubility Grain.
Further, the herbicide containing pretilachlor, pyraclonil and mesotrione is preventing and kill off transplanting rice field and rice Application in rice seedling bed, rice transplanting rice field annual grassy weeds.
Further, it is annual that the herbicide containing pretilachlor, pyraclonil and mesotrione is applied to transplanting rice field Weeds are grassy weed, broad leaved weed and sedge weed.
The invention has the advantages that：
1st, the present invention to the accounting component of pretilachlor, pyraclonil and mesotrione in herbicidal composition by carrying out Optimize, and the preparation granules of herbicidal composition are made up of the preparation technology after optimization, be easy to storage to transport, and in dispenser It is easy to make up a prescription；
2nd, the preventive effect for the herbicidal composition that pretilachlor, pyraclonil and mesotrione three are hybridly prepared into is better than each group Divide activity when being administered alone, while expand the control of weeds spectrum of direct sowing rice field, reduce direct sowing rice field spraying times, reduce anti- Cost is controlled, slows down the generation of Weed Resistance, it is good to crop safety, meet the security requirement of pesticidal preparations；
3rd, the present invention adds triacontanol in the herbicide granule of pretilachlor, pyraclonil and mesotrione and to chlorobenzene Fratol so that the herbicide granule of pretilachlor, pyraclonil and mesotrione both can effectively prevent and treat transplanting rice field All kinds of weeds, it can also strengthen the healthy strong growth result of transplanting rice；
4th, it is of the invention to big portions such as transplanting rice field nakedflower triquetrousc murdannia herb, moleplant seed, difformed galingale herb, angustifolia arrowhead herb, barnyard grasses Transplanting rice field weed is divided all to there is preferable preventive effect and to Security of rice height.
Certainly, any product for implementing the present invention it is not absolutely required to reach all the above advantage simultaneously.
