Abstract
The invention relates to a microcapsule suspending agent which takes spinosad as an active ingredient. Capsule-core spinosad is coated with a polyurethane type semipermeable envelope so as to form a microcapsule which is stably dispersed and suspended in water and is milk-white homogeneous-phase suspension liquid. A pesticide composition has good prevention and control effects on plutella xylostella. The occurrence of medicament resistance is delayed, environmental pollution is reduced and lasting period is prolonged.
Description
Technical field
The present invention relates to multiple killing teichomycin is the micro-capsule suspension pesticides new formulation of active ingredient.
Background technology
It is a kind of macrolides Nuisanceless high-efficient biological insecticides that extract in the sugared many born of the same parents fermented liquid of thorn that multiple killing teichomycin has another name called pleocidin (Spinosad).Produce parent strain soil actinomycetes thorniness saccharopolyspora strain (the Saccharopolyspora spinosa Metrz ﹠amp of pleocidin; Yao) initial separation is from one of the Caribbean discarded wine brewing field.The mode of action novelty of pleocidin can sustained activation target insect acetylcholine nicotine receptor, but its binding site is different from nicotine and Imidacloprid.Pleocidin also can influence the GABA acceptor, but mechanism of action is unclear.Whether also do not know at present has cross tolerance with the insecticide of other types.These compounds can cause that target plant-feed insect such as caterpillar, leaf miner, thrips and leaf-feeding beetle are dead rapidly, although administrative department's strong request is not used when resistance occurs, the moderate residual activity of this compound has reduced resistance and the living possibility of mass-sending.The acting body of nicotinic acid acetylcholinergic receptor can sustained activation target insect acetylcholine nicotine receptor, but its binding site is different from nicotine and Imidacloprid.Pleocidin also can influence the GABA acceptor, insect is had tag fast and stomach poison function, and blade is had stronger osmosis, can kill subepidermal insect, and the longevity of residure is longer, and some insects are had certain ovicidal action.No systemic action.Can effectively preventing Lepidoptera, diptera and thrips insect, can prevent and treat well also that some measures the pest species of food blade greatly in coleoptera and the orthoptera, relatively poor to the control efficiency of sucking pest and mite class.Safer to the predator insect, unique because of insecticidal action mechanism, do not find as yet at present to have mutual drug-fast report with other insecticides.Plant safety there is not poisoning.Be suitable for using on vegetables, fruit tree, gardening, the crops.Can make insect benumb rapidly, paralyse, cause death at last.Its desinsection speed can compare favourably with chemical pesticide.Safe, and do not have the biological insecticides that cross resistance is low toxicity, efficient, low-residual with present common insecticide, existing insecticidal properties efficiently has again the characteristic of beneficial insect and mammalian safe being arranged, the most suitable pollution-free vegetable, fruit production application.
Micro-capsule suspension (microcapsule suspensions) has another name called the capsule with diuresis promoting function suspending agent, it is one of agricultural chemicals type type of obvious regulation development in China's Tenth Five-Year Plan Period agricultural chemicals industrial policy, this formulation is that active component (capsule-core) is wrapped to form the even homogeneous suspension liquid that disperses also stably to be suspended in the water of microcapsules by cyst wall, capsule grain diameter is generally between 1～20 μ m, capsule-core slowly discharges under the control of cyst wall, to satisfy the control requirement.Through Beijing Office for Scientific and Technical Information update search, domestic with the disclosed 8% cypermethrin microcapsule formulations that the development of Jiangsu red sun group company is arranged, process by oil-soluble and water miscible cyst material and cypermethrin with interfacial polymerization, 50% malathion micro-capsule suspension of the big development of Zhejiang worker, replace synthesized polymer material with natural polymer algin-gelatin, the bacillus thuringiensis,Bt microcapsule formulations that the inferior woods of 25% parathion microcapsule formulations and Chinese forest-science academy that also has Liaoning Province's silkworm and mulberry to be developed is in addition developed.
Summary of the invention
The present invention also adopts interface polycondensation that the material of following component and content (percentage by weight) is processed into the multiple killing teichomycin micro-capsule suspension.
Multiple killing teichomycin 1～10%
Toluene di-isocyanate(TDI) (TDI) 0.3～0.4%
Three methanol-based aminomethanes (TWX) 0.05～0.15%
Organic solvent 1～3%
Surfactant 1～2%
Emulsifier 2～4%
Xanthans 0.25～0.35%
Antifreeze, preservative 4～6%
Water surplus (complementing to 100%)
Described organic solvent is arene such as benzene, toluene etc.
Described surfactant can use agricultural emulsifier, as farming breast 0201,0203 etc.
Described emulsifier is an agricultural emulsifier.
The interfacial polycondensation preparation method adds two kinds of monomer TDI and TWX in the organic solvent that is dissolved with multiple killing teichomycin to stir, then this organic facies is added in the water that contains surfactant in the reaction 2.5～3.5 hours down of 45～55 ℃ of temperature condition, add other auxiliary agent emulsifier, xanthans, antifreezing agent and preservative at last and stir and just obtain the multiple killing teichomycin micro-capsule suspension.
The present invention wraps up the formation microcapsules with the capsule-core multiple killing teichomycin with the semipermeability cyst membrane of polyurethane-type, and stable dispersion, is suspended in the water, and outward appearance is a milky homogeneous suspension liquid body.Liquid chromatography analysis active constituent content 0.3～2, by GB GB/T1605, GB14825, GB/T1601, the sampling of regulation such as GB16125, analytical method regulation, suspensibility (%) 〉=85, pH=5～7,75 μ m testing sieve screen analysises (%) 〉=98, low temperature and heat-storage stability are qualified.
This product 2.5% multiple killing teichomycin micro-capsule suspension is as follows through Beijing YanHuaYongLe pesticide Co., Ltd's field test results:
2.5% multiple killing teichomycin micro-capsule suspension has higher preventive effect to diamond-back moth, and there is the longer lasting period than regular missible oil kind, 60ml/667 ㎡ preventive effect is more than 80%, 80 ml/667 ㎡ preventive effects are more than 90%, catch up with and surpass first and tie up salt and efficient chlorine fluorine cyanogen polyester, and to the vegetables high safety, to people's safety non-toxic, vegetables are sprayed and can pluck edible in back 1 day.
2.5% multiple killing teichomycin micro-capsule suspension control cabbage caterpillar effect is remarkable, instant effect, and the lasting period is long.With 60,80, three dosage dispensers of 100ml/667 ㎡ after one day preventive effect be respectively that preventive effect is respectively 86.27%, 93.08% and 97.88% after 83.72%, 91.6% and 94.65%, seven day, be higher than control group 4.5% efficient cyhalothrin emulsifiable concentrate and 5% first dimension salt missible oil.
