Description

A kind of microcapsule preventing and treating poplar longicorn notes dry pesticide manufacture method
Technical field
The present invention relates to a kind of microcapsule preventing and treating Insect Pests In Poplars Anoplophorae seu Aprionae and note dry pesticide manufacture method, belong to chemical industry pesticide field.
Background technology
Willow is drought-enduring, tall and big tall and straight, is one of the Main Cultivation seeds of China artificial forest, and three Norths buffer zone is also based on willow. The Roadside forest belt seeds more than 70% of the northern area of China are all Cortex Populis dividianae.Poplar longicorn is a kind of coleoptera borer pest.Anoplophorae seu Aprionae Larva burrows at willow xylem and eats into food, very harmful.Owing to willow is up to tens meters, roundheaded borer is hidden again in trunk, Spraying insecticide from outside and prevent and treat Anoplophorae seu Aprionae, pesticide dosage is the highest, and waste is serious, and the lasting period is extremely short, and prevention effect is very poor.
A difficult problem for headache is compared in the preventing and treating of poplar longicorn always forestry.Relatively effective prevention and controls is to punch at trunk root, Injection, but traditional pesticide discharges soon in trunk, easily causes poisoning, and the lasting period is short, within 1 year, need to note 2-3 medicine.
Summary of the invention
It is an object of the invention to provide a kind of microcapsule preventing and treating poplar longicorn and note dry pesticide manufacture method, use the method made The microcapsule made notes dry pesticide can prevent and treat poplar longicorn well, specifically includes following steps:
(1), micro-by being ground to particle diameter≤3 after chitinase inhibitors, synthetic anabasine insecticide and dispersant Rice, stand-by；
(2), the mixture that step (1) obtains is put in reactor, then add organic solvent, surfactant and Stannous octoate, after stirring, makes pesticide matrix；
In pesticide matrix, by mass percentage, containing chitinase inhibitors 10-30%, synthetic anabasine insecticide 10-30%, dispersant 40-69.5%, organic solvent 5-20%, surfactant 5-20% and stannous octoate 0.5-2%；
(3), adding the aqueous solution of microcapsule wall material again in reactor, stirring carries out encystation reaction, makes the dry agriculture of microcapsule note Medicine；
In the aqueous solution of microcapsule wall material, the amount containing microcapsule wall material is chitinase inhibitors and synthetic anabasine insecticide The 10-20% of gross mass；
Described chitinase inhibitors is chloromethiuron, the one in tebufenozide, Cascade, HEXAFLUMURON or d ichlorbenzuron；
Described synthetic anabasine insecticide is Acetamiprid, clothianidin, gives a tongue-lashing in worm quinoline, MTI-446, thiacloprid or Diacloden One；
Described dispersant is the one in diesel oil, kerosene, methyl oleate, benzoic acid Bian ester or dimethylformamide；
Described machine solvent is the one in dimethylformamide, dimethyl acetylamide, dimethyl sulfoxide, methanol or ethanol.
Chitinase inhibitors is the highest to coleoptera larvae activity, can destroy the decortication mechanism of insect, block reproductive process, at soil In earth, trunk, water the most stable.Synthetic anabasine pesticide is the most sensitive to coleopteran pest, inhales in having again plant Conductive performance, can spread rapidly in trunk.In water, dissolubility is the lowest, sufficiently stable.Above two pesticide is made raw material multiple Join and be prepared as microcapsules SC for noting dry preventing and treating poplar longicorn.
In the present invention, first pesticide is ground, to increase the solubility property of pesticide, and adds dispersant when grinding, Strengthen the effect ground, after grinding completes, add organic solvent, surfactant and stannous octoate, and stir, so that agriculture Medicine can be substantially dissolved in organic solvent, is eventually adding microcapsule wall material, and with water level continuous phase, is stirred, makes various Material encystation reacts, and makes microcapsule and notes dry pesticide.
Further, in step (3), it is additionally added ethylene glycol, makes the microcapsule made note in dry pesticide containing 10-15% volume ratio Ethylene glycol.The addition of ethylene glycol can reduce microcapsule and note the freezing point of dry pesticide, strengthens the freeze-proof of pesticide.
Further, in step (2), being additionally added cinnamic aldehyde in a kettle., the addition of cinnamic aldehyde is chitinase suppression Agent and the 1-2% of synthetic anabasine insecticide gross mass.The addition of cinnamic aldehyde can strengthen microcapsule and note the medicine of dry pesticide Effect.
In step (2), being additionally added silane coupler in a kettle., the addition of silane coupler is chitinase inhibitors 2-3% with synthetic anabasine insecticide gross mass.The addition of silane coupler can strengthen the encystation effect of microcapsule wall material Really.
Further, one or both during described surfactant is tween, span or dodecylbenzene sodium sulfonate.These surfaces Activating agent is conventional surfactant, it is easy to obtains, and disclosure satisfy that the needs of the application.
Described microcapsule wall material is the one in gelatin, alginate jelly or arabic gum；These materials are conventional microcapsule wall materials, Disclosure satisfy that the needs of the application.
Described microcapsule wall material can also be the one in Polyethylene Glycol, polyvinyl alcohol, acrylic acid methyl ester. or acrylamide, and can Being simultaneously introduced the one in carbamide, Ammonium persulfate. or potassium peroxydisulfate, the addition of carbamide, Ammonium persulfate. or potassium peroxydisulfate is micro-glue The 1-2% of cyst wall material amount.Above-claimed cpd can also add carbamide, mistake as microcapsule wall material in these microcapsule wall materials One in ammonium sulfate or potassium peroxydisulfate, can strengthen the response speed of these microcapsule wall materials.
Microcapsule manufactured by the present invention notes the using method of dry pesticide: in distance ground below 30cm place's boring, be then injected into Microencapsulation of pesticide, and block medicine-pouring hole with plastic foil bag earth.Microencapsulation of pesticide has the function controlling release.When microcapsule agriculture Medicine rises diffusion by after the amount release of design with xvlem fibres tube bank, is finally enriched with at leaves edge, can kill the food on willow Leaf insect.The microcapsule note dry pesticide lasting period of the present invention is more than 90% up to 2-3, the effect of preventing and treating Anoplophorae seu Aprionae and leafeating insect, A large amount of cost accounting can be saved.
Calculating by the diameter of a cross-section of a tree trunk 1.3 meters above the ground of willow, the diameter trunk less than 15cm makes a hole, injection 15ml-30ml；Diameter is more than or equal to 15cm, less than the trunk of 30cm, makes a call to 2 holes, total injection 15ml-30ml；The diameter trunk more than or equal to 30cm, boring 2-4, injection calculates every centimetre of injection 1ml by diameter；Aperture is 6-8cm, hole depth 5-8cm.
