Description
Technical field
The present invention relates to method for producing insecticide field, particularly relate to a kind of stable type agricultural chemicals suspension agent and preparation method thereof.
Background technology
Pirimiphos-methyl (pirimiphos-methyl), have another name called that Actellic, methyl Midinyanglin, Actellic, Bao'an are fixed, Ya Tesong etc., developed in 1974 by ICI company (being now Jie Likang agro-chemical companies), active ingredient chemical name is O, O mono-dimethyl-O-2-diethylamino-6-methylpyrimidine-4-base phosphorothionate.
Pirimiphos-methyl is a kind of low toxicity, quick-acting organophosphorus insecticideses and miticide, has stronger stomach toxicity, tags, smokes
Steaming effect and good osmosis.Pirimiphos-methyl chewing class and sucking the control of class pest and larva not only on the crops such as fruit tree, cotton, vegetables, and be widely used in control grain storage insect and sanitary insect pest, control efficiency is good especially, is the improved seeds of control storage pest and sanitary insect pest.Compared with general insecticide, pirimiphos-methyl has the advantages such as holding effect is long, consumption is few.Along with domestic organophosphorous pesticide key variety acephatemet, ethyl parathion, parathion-methyl, nuvacron; Phosphorus ammoniums etc. are completely forbidden because toxicity is too high and are produced, sold and used, and pirimiphos-methyl becomes the adapted varieties of alternative the said goods, gradually by everybody is approved, has good market prospects and development potentiality.
Current pirimiphos-methyl is mainly used in health, storage is used.Pirimiphos-methyl can be processed into missible oil, aqueous emulsion, mainly contains 50% pirimiphos-methyl missible oil, 20% pirimiphos-methyl aqueous emulsion, 10% pirimiphos-methyl aqueous emulsion at present in the formulation of China's registration.Missible oil needs to consume a large amount of organic solvents, and both contaminated environment, waste resource again, have listed superseded ranks in; Although aqueous emulsion greatly reduces the consumption of organic solvent; for positive role is played in environmental protection, but owing to introducing a large amount of water in preparation, thus active ingredient is made to be easier to decompose; preparation physical stability is poor, and the development of pirimiphos-methyl aqueous emulsion is very limited.And microcapsule suspending agent can well overcome this problem.
Chlopyrifos (chlorpyrifos), O, O-diethyl-O-(3,5,6-trichloro-2-pyridyl) D2EHDTPA, has slight mercaptan taste.Non-internal-absorting broad spectrum disinfestation, miticide, have stomach toxicity, tag, fumigate triple role, all have favorable effect to chewing type multiple on paddy rice, wheat, cotton, fruit tree, vegetables, tea tree and sucking pest.Mixed compatibility is good, can with multiple Mixture Use of Insecticides and synergistic effect is obvious, and toxicity is low compared with conventional pesticide, to natural enemies security, is the first-selected medicament of alternative high-toxic organic phosphorus agricultural chemicals.Insecticidal spectrum is wide, and the organic matter be easy in soil combines, and to soil insect special efficacy, the lasting period reaches more than 30 days.Without systemic action, ensure the safety of agricultural product, consumer, be applicable to the production of pollution-free high-quality agricultural product, be widely applied in agricultural and health pest control.Domesticly be mainly processed into missible oil to use at present, in recent years, also occurred the report of chlorpyrifos aqueous emulsion, microemulsion product successively, but the chlopyrifos of these formulations also exist some shortcomings in the application:
Chlopyrifos system photaesthesia agricultural chemicals, decomposes rapidly in the sun, and the formulation such as missible oil, microemulsion cannot solve chlopyrifos light resolution problem, and secondly chlopyrifos there will be poisoning to sensitive crop, and such as melon, leaf vegetables even some rhizome vegetables, safety is lower.In soil, volatility is higher, reduces the preventive effect of chlopyrifos.
Based on these two weakness of chlopyrifos, the micro-capsule class formulations such as my company's research and development chlopyrifos microcapsule suspending agent, make the active ingredient lasting period long, effective rate of utilization is high.
Gamma cyhalothrin, yellow to viscous brown oily liquid (industrial goods), boiling point 187-190 DEG C/0.2mmHg, vapour pressure is about 0.001mPa (20 DEG C), density 1.25 (25 DEG C), 0.004ppb (20 DEG C) in solvability water, be dissolved in acetone, carrene, methyl alcohol, ether, ethyl acetate, hexane, the equal >500g/L of toluene (20 DEG C), 50 DEG C of dark places deposit and do not decompose for 2 years, stable under light, 275 DEG C of decomposition, under light, pH7-9 slowly decomposes, and pH>9 accelerates to decompose; Insecticidal spectrum is wide, and activity is higher, and drug effect is rapid, resistance of rainwater washing against after spraying, but Long-Time Service easily produces resistance to it, has certain preventive effect, but increase 1-2 doubly to the using dosage of mite than conventional amount used to the insect of sucking mouth parts and evil mite.Be applicable to the insect of peanut, soybean, cotton, fruit tree, vegetables.The mechanism of action of gamma cyhalothrin suppresses the conduction at insect neural axon position, insect had to the feature of walking quickly and keeping away, knock down and killing.
Metalaxyl, chemical name D, L-N-(2,6-3,5-dimethylphenyl)-N-(2-methoxyl group acetyl) methyl lactamine, molecular formula: C15H21NO4, white powder, micro-have volatility, more stable under neutrality and solutions of weak acidity, meets alkali and easily decompose.To people, animal low toxicity, there is slight spread effect to skin, eye, lower to birds, fish, honeybee toxicity.Disease is had to the bactericidal actions such as protection, treatment and interior suction, resistance of rainwater washing against, 10 ~ 14 days lasting periods.To the microbial various crop downy mildew of Pseudoperonospora cubensis, phytophthora root rot bacterium and maize ear rot, phytophthora root rot, the millet downy mildew of gourd, fruit and vegetable class are effective.Single Long-Time Service, easily produces resistance, and product is prepared into microcapsule suspending agent, can reduce product resistance, increases the stability of product.
The molecular formula of alachlor: C14H20ClNO2; Sterling is crystallization.Fusing point 40-41 DEG C.When 23 DEG C, in water, solvability is 240ppm.Dissolve in acetone, benzene, ethanol, ethyl acetate.Volatility is minimum.Uvioresistant is decomposed.Decompose under strong acid or alkali condition.In soil, the half life period is about 15d.
Be a kind of selectivity preemergence herbicide, mainly absorbed by the bud scale of weeds, root and seed also can have a small amount of absorption.Mainly kill the weeds sprouted in soil before emerging, invalid to weeds of being unearthed.Not easily leaching loss can be adsorbed by soil granular, not volatile yet, but can be decomposed by edaphon.The term of validity is about 35 days.The scope of application is applicable to the crop fields such as soybean, corn, peanut, cotton, potato, sugarcane, rape, prevent and kill off barnyard grass, lady's-grass, yard grass, green foxtail, the autumn barnyard grass, Brachiaria Griseb, kitchen garden, amaranth, verticillate carpet weed, lamb's-quarters, 1 year raw grassy weed and the broad leaved weed such as knotweed.Also certain preventive effect is had to dodder.
Alachlor effectively can prevent and treat most of annual gramineae and some broadleaf weed.Also can be used for the vegetable field weedings such as cotton, sugarcane, rape, tobacco, onion and radish.
Current alachlor single dose formulation is mainly missible oil, and missible oil needs to consume a large amount of organic solvents, and both contaminated environment, waste resource again, have listed superseded ranks in; For positive role is played in environmental protection, but owing to introducing a large amount of water in preparation, thus make active ingredient be easier to decompose, preparation physical stability is poor, and the development of alachlor aqueous emulsion is very limited.And microcapsule suspending agent can well overcome this problem.
First generation microcapsule suspending agent adds organic solvent usually in preparation process, along with the development of microcapsule suspending agent technology of preparing, start the physico chemical property progressively utilizing active ingredient itself, select suitable capsule material, under the condition not adding organic solvent hydrotropy, form stable microcapsule structure.
