Description
Technical field
The present invention relates to biological insecticides composition production technical field.
Background technology
In recent years, because a large amount of uses of various agricultural chemicals cause the pest pesticide resistance more and more higher, be China's insect pest of rice as water rice hopper, striped rice borer, paddy stem borer, rice leaf roller, take place particularly serious in Yangtze river basin rice district.Can cause a large amount of withered hearts in tillering stage, except that causing dead ears, also cause a large amount of insect bite strains, make its lodging in blocks at late growth stage of rice.Vegetables and flower plants and nursery stock insect are the major reasons that danger to vegetables and flower plants and nursery stock are produced for another example, in recent years, though country's order is forbidden using high-toxic pesticide on vegetables and flower plants and nursery stock, but often have because edible vegetables and use, the ornamental flower nursery stock that contains residual high-toxic pesticide causes poisoning, therefore, the agricultural chemicals of development high-efficiency low-toxicity, the low-residual development trend that is inevitable.
In chemical agent control, at present the pesticide species that mainly uses above-mentioned crops as: clam worm toxicity agricultural chemicals such as desinsection list, dimehypo have produced very strong pesticide resistance, agricultural chemicals such as the Hostathion of Shi Yonging, Imidacloprid in succession, pesticide resistance is obviously rising also.The good agricultural chemicals of control efficiency has kinds such as fluorine worm nitrile, happiness at present, but because the price height, quick-acting is poor slightly, and certain limitation is in use arranged.
Secondly,, seek to reduce the risk that agricultural chemicals and use thereof bring, become the much-talked-about topic of formulation art by the innovation of preparation technique along with pesticide hazards problem and people become increasingly conspicuous to the concern of living environment.Many agricultural chemicals experts point out after looking back the problem that relevant pest resistance to insecticide administers, the skewness of agricultural chemicals be since the operation technique and the formulations of pesticide be not suitable for cause; And emphasize in pesticide resistance comprehensive regulation strategy from now on, must be the formulations of pesticide and technique in using agriculture chemical necessary component as resistance management research.Have research to point out, as the actual dose that is subjected in the pest target, approximately be no more than 6% of field dosage in extensive farmland dispenser process, be no more than 0.1% but most applications is next, greatly part is all missed the target.In view of this, cause the main cause of current agricultural chemicals environmental problem also not exclusively to be to be unfavorable formulation and operation technique to a great extent by agricultural chemicals itself.The factor of technical development simultaneously is to promote the most direct influence factor of pesticide greening purification.Technology such as the suspending agent of developing in recent years, the agent of kind clothing, microcapsule formulations, microemulsion, water dispersible granules are based on the effective way of modern preparation processing technology pesticide greening purification.Suspending agent is in the main trend that reduces consumption of organic solvent, uses and store and transport safe ready, the lasting period is long, the characteristics that do not produce aspects such as " three wastes " in producing have been complied with pesticide greening purification.From above-mentioned meaning, be the water-base preparation of representative with the suspending agent, will become one of important means that solves the pesticide hazards problem.Suspending agent (suspension concentration) claim aqueous suspension agent, colloidal suspending agent, concentrated suspension again, is the important formulation of a class of the contemporary farm chemical preparation technology developing direction of representative.Its basic principle is under surfactant and other promoter effects, and former medicine insoluble or that be insoluble in water is distributed in the water, forms uniform and stable thick suspension system.Suspending agent is mainly adjusted agent, defoamer and water etc. by pesticide original medicine, wetting agent, dispersant, thickener, antifreezing agent, pH and is formed.Because its dispersion medium is water, cost is low so suspending agent has, production, storing and characteristics such as safe in utilization, and can mix with arbitrary proportion with water, not influenced by water quality, water temperature, and is easy to use.Compare with the formulations of pesticide that with the organic solvent are medium, have advantages such as the little and poisoning of environmental influence are light.
Avermectin and nimbin all are that present range of application is wide, the comparatively effective biological insecticides of control.
Nimbin is the vegetable insecticide that extracts from seal chinaberry seed, insect has food refusal, avoid keep away, interior suction and suppress growth with the effect of educating.Mainly act on the endocrine system of insect, reduce the burst size of moulting hormone; Also to directly destroy epidermal structure or stop the chitinous formation of epidermis, or disturb respiratory metabolism, influence genital system growth etc.Safer to environment, people and animals, natural enemy, insect is difficult for developing immunity to drugs.Nimbin is a biopesticide, and drug effect is slower, but the lasting period is long.
Avermectin is a kind of macrolide disaccharide compounds.Be the natural products that from edaphon, separates, insect and mite class had tag and stomach poison function and faint fumigation action is arranged, no systemic action.But it has very strong osmosis to blade.Can kill subepidermal insect, and the longevity of residure is long.It does not kill ovum.What its mechanism of action was different with general insecticide is that it disturbs the neurophysiology activity, stimulate and discharge the r-aminobutyric acid, and the r-aminobutyric acid has inhibitory action to arthropodan nerve conduction, the one-tenth of mite class, if mite and insect with larva with paralysis symptom promptly appears after medicament contacts, inertia is not got food, and is dead after 2-4 days.Because of not causing that insect dewaters rapidly, so its lethal effect is slower.Though though predatism and parasite there are direct killing effect, because of plant surface is residual few, therefore little to the damage of beneficial insect.
The more important thing is that Avermectin and nimbin all are based on the missible oil formulation in the market, product cost height not only, drug effect is poor, and has caused serious environmental to pollute and the excess waste of resource in the product use.
