Description
Technical field
The invention belongs to technical field of pesticide preparations, relate in particular to a kind of solid lipid nano spinosad and preparation method thereof and the application on pesticidal preparations.
Background technology
It is a kind of macrolides harmless boilogical insecticide that extracts in thorn sugared many born of the same parents bacterium (Saccharopolysporaspinosa) zymotic fluid that multiple killing teichomycin has another name called pleocidin (Spinosad).
Pleocidin has insect tags and stomach poison function fast, and blade is had stronger osmosis, can kill subepidermal insect, and the longevity of residure is long, and some insects are had certain ovicidal action.Without systemic action.Can effectively preventing Lepidoptera, diptera and thrips insect, can prevent and treat well also that in coleoptera and orthoptera, some takes food the insect insects of blade in a large number, poor to the control efficiency of sucking pest and mite class.
Its mechanism of action is considered to 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 affect the GABA acceptor, and its desinsection speed can compare favourably with chemical pesticide.Safe, and with present common insecticide without cross resistance, be the biological insecticides of low toxicity, efficient, low-residual, existing efficient insecticidal properties has again the characteristic of beneficial insect and mammalian safe is arranged, and is the insecticide of a kind of low toxicity, efficient, wide spectrum.
Pleocidin is widely used in composite with other agricultural chemicals, to increase insecticidal spectrum, improves preventive effect and cost performance.publication number CN101380004 Chinese invention patent application discloses with lufenuron and pleocidin composition pesticide and the preparation method as active component, the Patent Application Publication of publication number CN101180959 with capillary and pleocidin composition pesticide and the preparation method as active component, the Patent Application Publication of publication number CN101305723 with capillary and pleocidin composition pesticide and the preparation method as active component, the Patent Application Publication of publication number CN101248798 with diafenthiuron and pleocidin composition pesticide and the preparation method as active component, the Patent Application Publication of publication number CN101305723 with Diacloden and pleocidin composition pesticide and the preparation method as active component.But because pleocidin is seen light and easily decomposed, hydrolysis is very fast, and in water, the half life period is 1 day; In soil half life period 9-10 days, the barrier that the chemical stability after making it composite and the photodissociation in use procedure become its combination application technique development of restriction.The preparation that experiment showed, above composition exists seriously decomposition in the cold and hot storage process of active component pleocidin, photodissociation in use procedure, degradation problem under drug effect.
Nanometer technology is a new technique, nanosecond science and technology belong to the forward position cross discipline, nanometer technology and Application of micron are comprised nanoparticle (Nanoparticles, NP) in the system of field of pharmaceutical preparations, nanocapsule (Nanocapstles, NC), nano-micelle (Nanomicelle, NM), lipid nanometer body (Nano-liposemes, NL) and nanometer microemulsion (Nano-emulsion, NE) etc.Wherein NP generally refers to by natural or macromolecular material is made, and granularity is at nanoscale (1.0-500nm) solid colloid particulate, or is called colloid bearer (colloidal.carriers).Active component is positioned at inside particles by dissolving, package action.This novel pharmaceutical preparation has slow-release function, can improve medicine stability, dispersiveness, service efficiency and drug effect simultaneously.Solid lipid nano (Solid lipid nanopartides, SLN) be with natural or synthetic lipoid as carrier matrix, active ingredient is wrapped in lipoid core.At present, there is no the report that solid lipid nano spinosad prepares and be applied to pesticidal preparations both at home and abroad.
