Abstract
The invention relates to the technical field of plant protection, specifically to a soluble granule for preventing and treating disease and insect damage to Radix Astragali. The invention provides the soluble granule with the advantages of stable properties, simple and smooth production process and no proneness to moisture absorption, and a preparation method thereof. The soluble granule is prepared from water-insoluble or water-microsoluble pesticide effective ingredients and composed of effective ingredients, a wetting dispersant, an osmotic agent and a filling material, so the problem of easy decomposition of pesticide effective ingredients in a solvent is overcome.
Description
Technical field
The present invention relates to technical field of plant protection, specifically a kind of soluble granula preventing and treating Radix Astragali pest and disease damage.
Background technology
Radix Astragali pest control is in numerous insects of the Radix Astragali, and harm is serious, cause economic loss bigger have heart-eating worm, Radix Brassicae rapae and aphid three class.The heart-eating worm of the harm Radix Astragali is mainly astragalus membranaceus seed chalcid fly, secondly also has 4 kinds of insects such as bean-pod borer, Herba Medicaginis, noctuid, bollworm, green vegetable worm；What Radix Astragali disease often occurred has powdery mildew, rust, root rot, southern blight, damping-off, droop, Radix Astragali purple root rot (Helicobasidium mompa) etc..
The normally used formulations of pesticide, such as powder, wettable powder, cream, suspending agent etc., after using, effective ingredient is all sufficiently exposed in place, very easily causes poisoning and to beneficial organism killing action for the medicament that toxicity is high.Additionally due to reasons such as the leaching loss of photodissociation, hydrolysis, biodegradation or water, air volatilizations, the field lasting period of medicament is also greatly shortened.
Chinese patent CN101657093A discloses a kind of sterilization soluble granula containing ether bacterium fat and preparation method thereof, patent No. CN101564044A discloses a kind of containing soluble granule of glyhosate ammonium and preparation method thereof, acephate soluble granula that patent No. CN101427672A is stable and preparation method thereof, the summary of the invention of foregoing invention is single, prevention and treatment range is narrow, the present invention is to insecticide, the multiple preparation of antibacterial Multiple Pesticides, it is achieved the preparation to multiple pest control chemicals.
Utilization the invention enables water-soluble active ingredients to obtain water miscible effect, it is under same working concentration, and disintegration rate is fast, and effective ingredient can disperse rapidly and be dissolved completely in water, show as the true solution of transparent and homogeneous, owing to effective ingredient can be fully water-soluble, its particle diameter is less, and maximizing improves its bioavailability, reduce field service wear, and owing to preparation not containing or containing minimal amount organic solvent, environmentally safe property height, pollute little.Its maximum breakthrough is that and water-insoluble former medicine is achieved water-solubleization and solidification, is not only greatly improved drug effect, and is used conveniently and safely.Being Biodegradable material due to the auxiliary agent used, carrier etc., environmental pollution is little, basic noresidue, thus being expected to substitute the non-environmental protection dosage form product such as cream, microemulsion, wettable powder, becomes the once big change that the formulations of pesticide are industrial.The advantage preparing formulation products of the present invention is in that preparation is made into when using medicinal liquid, and the degree of scatter of effective ingredient and biological activity ratio's cream, suspending agent and wettable powder formulation are high.Simultaneously compared to missible oil product, the degree of danger reveal under its room temperature, burn, exploded is substantially reduced；Compared to wettable powder and suspending agent type, production process is without comminution by gas stream or sand milling, and production efficiency is high, and dust is few, and production process cleans, and packed and transported is convenient.
Summary of the invention
It is an object of the invention to provide a kind of soluble granula preventing and treating Radix Astragali pest and disease damage, so that water-insoluble or water microsolubility pesticide active ingredient are prepared into water-soluble granule, it is possible to solve pesticide active ingredient and hold labile problem in a solvent.
For solving above-mentioned technical problem, the invention provides a kind of stable in properties, production process soluble granula simple, smooth, the not easily moisture absorption and preparation method thereof.
The technical solution used in the present invention is:
Including pesticide active ingredient, wetting dispersing agent, penetrating agent, filler composition；
Described pesticide active ingredient is one or more in the preventing and treating parasite killing of diseases and pests of agronomic crop, antibacterial, and insecticide includes heart-eating worm, Radix Brassicae rapae and control of aphids effect good: avilamycin, Acetamiprid, gamma cyhalothrin, chlopyrifos, aphid louse Suke, imidacloprid, d ichlorbenzuron 3, worm acyl, metrifonate, phoxim, Aphox, carbosulfan, cis fenvalerate, Fenpropathrin, Buprofezin, capillary；Prevent and treat powdery mildew and the antibacterial of rust class: triadimefon, lime sulfur, procymidone, Mancozeb, can kill, Bravo, thiophanate methyl, carbendazim, thiram, metalaxyl, how mould spirit, Sukeling, metalaxyl-mn-zn；The pesticide control of root disease includes: hymexazol, thiophanate methyl, amidine squama amine, fenaminosulf, carbendazim, the bacterium spirit that disappears, virus spy, Sheng Zhifeng, octicin solution, ZhiBingLing(SIC)；
Wetting dispersing agent is by lignosulfonates (sodium salt or calcium salt), Negel, condensation compound of methyl naphthalene sulfonic acid and formaldehyde sulfate, how sulfonic formaldehyde condensation compound, methanonaphthalene sodium sulfonate dibutyl how sulfonic formaldehyde condensation compound, N-Methyl fatty acyl taurines sodium, polycarboxylate, naphthalene sulfonate, tea seed cake powder, Saponin, lignosulfite, fatty alcohol polyoxyethylene ether sulfate, sodium lauryl sulphate, dodecylbenzene sodium sulfonate, pull open powder, one or more mixture of Aerosol OT.
Described penetrating agent is one or more the mixture in fatty alcohol-polyoxyethylene ether, aerosol-OT salt, laurocapram.
Described filler is one or more mixture of sodium sulfate, sodium chloride, potassium chloride, potassium sulfate, carbamide, lactose, glucose, sodium nitrate, potassium nitrate, white carbon.
Described soluble granula percentage by weight is: the pesticide active ingredient of 2%-60%, the wetting dispersing agent of 1%-30%, the penetrating agent of 1%-20%, surplus are fillers.
The preparation method of described soluble granula is:
(1) selected by pesticide original medicine weigh by weight percentage, through, to 325 order～400 orders, adding wetting dispersing agent, filler wherein；Penetrating agent adds ethanol, stirs, standby；
(2) mixture is carried out agravic mixing 5-10 minute, mixed process adds with spray pattern the mixture of ethanol and the penetrating agent got ready.
(3) extruder grain, dries at 50～80 DEG C, obtains the dry granule that grain diameter is 0.5～1.5mm；
(4) after screening, packaging prepares soluble granula to dry granule；Oversized particles or dust, dust-removing powder return pelletize again after agravic blender mixes with virgin material.
The beneficial effects of the present invention is:
