Description
Technical field
The present invention relates to a kind of Avermectin and the composite agricultural chemicals suspension agent of azacyclotin.
Background technology
Avermectin, English name: Abamectin, No. CAS: 71751-41-2.Avermectin is that the class first developed by Japanese North university large village intelligence etc. and Merck company of the U.S. has desinsection, kills mite, ten hexa-atomic Macrocyclic lactone compounds of eelworm-killing activity, is fermented produce by Avid kyowamycin Streptomycesavermitilis in streptomycete.Avermectin has stomach toxicity and action of contace poison to mite class and insect, can not ovicidal.Mechanism of action and general insecticide, unlike disturbing neurophysiology movable, stimulate release γ-aminobutyric acid, and aminobutyric acid have inhibitory action to arthropodan nerve conduction.
Azacyclotin, Chinese name: three (cyclohexyl)-(1,2,4-triazol-1-yl) tin, English name: Azocyclotin, CAS:41083-11-8.Belong to contact acaricide, if young mite mite, acarid such as one-tenth mite and summer egg etc. can be killed.
Agricultural chemicals suspension agent is the formulation of 20 century 70 development, has now become one of basic processing formulation.Suspending agent, also known as aqueous suspension agent, colloidal suspending agent, concentrated suspension, has cost low, the features such as production, storing and use safety, and easily mixes with water, easy to use.
Summary of the invention
For solving the deficiencies in the prior art, technical problem to be solved by this invention is to provide a kind of Avermectin and the composite agricultural chemicals suspension agent of azacyclotin.Be achieved especially by following technical proposals:
Avermectin and the composite agricultural chemicals suspension agent of azacyclotin, comprise the raw material of following weight percentage: Avermectin 0.5-1.5%; Azacyclotin 10-25%.
Avermectin and the composite agricultural chemicals suspension agent of azacyclotin, be made up of following materials by weight percentage: Avermectin 0.5-1.5%; Azacyclotin 10-25%; Surfactant 5-9%; Ethylene glycol 5-7%; Carbomer 0.05-0.15%; Cetanol 0.1-0.3%; Propylben 0.01-0.03%; Surplus is water.
Described surfactant is poly-(Oxy-1, the 2-ethylidene) non-ionic surface active agent of succinate sodium 2-ethylhexyl and/or α-[three (phenyl methyl) phenyl]-ω-hydroxyl.
Described surfactant, is made up of 40-60 weight portion succinate sodium 2-ethylhexyl and poly-(Oxy-1, the 2-ethylidene) non-ionic surface active agent of 40-60 weight portion α-[three (phenyl methyl) phenyl]-ω-hydroxyl.
α-[three (phenyl methyl) phenyl]-ω-hydroxyl gathers (Oxy-1,2-ethylidene) non-ionic surface active agent, CAS:64422-66-8, molecular formula: (C

24o.Succinate sodium 2-ethylhexyl, also known as: Aerosol OT, No. CAS: 577-11-7.
PH adjusting agent can also be added according to actual needs in formula.
Avermectin of the present invention and the composite agricultural chemicals suspension agent of azacyclotin can adopt the general method in this area to be prepared, and one is ultramicro grinding method, and another kind is coacervation.
Concrete, described ultramicro grinding method:
(1) according to formula, Avermectin, azacyclotin, surfactant, ethylene glycol, carbomer, cetanol, propylben and water are uniformly mixed pulp thing, are placed in ball mill and pulverize.
(2) be placed in skin grinder and carry out ultramicro grinding, control average grain diameter 2-4 μm.
(3) be placed in homogenizer homogeneous, make particle homogenization.
Avermectin of the present invention and the composite agricultural chemicals suspension agent of azacyclotin have higher suspension rate, stable during long-term storage.Test proves, have good control efficiency, and safety is good, to crops without poisoning to the insect pest of multiple fruit tree and vegetable, mite evil.
