Description
Technical field
The present invention relates to agricultural chemicals and preparation method thereof, relate in particular to a kind of Avermectin spinosad aqueous emulsion of preventing and treating the crop pests such as paddy rice rice leaf roller, striped rice borer, paddy stem borer and vegetables diamond-back moth, beet armyworm and preparation method thereof.
Background technology
Multiple killing teichomycin is the soil actinomycetes metabolite, is safe, efficient, as to derive from natural products a kind of insecticide.The mode of action of multiple killing teichomycin is novel, 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, can make insect benumb rapidly, paralyse, and causes at last death.Its desinsection speed can compare favourably with chemical pesticide.Safe, and be the biological insecticides of low toxicity, efficient, low-residual with present common insecticide without cross resistance, existing efficient insecticidal properties has again the characteristic of beneficial insect and mammalian safe is arranged, and the most suitable pollution-free vegetable, Production of fruit are used.It is the insecticide of a kind of low toxicity, efficient, wide spectrum.Insect is had tag fast and stomach poison function, blade there is stronger osmosis, can kill subepidermal insect, the longevity of residure is longer, some insects are had certain ovicidal action, without systemic action, energy effectively preventing Lepidoptera, diptera and thrips insect, can prevent and treat well also that in coleoptera and orthoptera, some takes food the pest species of blade in a large number, relatively poor to the control efficiency of sucking pest and mite class.Safer to predatory natural enemy insect, unique because of insecticidal action mechanism, not yet find at present to have mutual drug-fast report with other insecticides.Safe without poisoning to plant.Be suitable for using on vegetables, fruit tree, gardening, crops.Insecticidal effect be subjected to rain affect less.
Avermectin is a kind of antibiotics insecticidal/acaricidal agent of efficient, wide spectrum.It is comprised of one group of macrolides compound, and active substance is AVERMECTIN, is the natural products that separates from edaphon, insects and mites is had tag with stomach poison function and faint fumigation action is arranged, without systemic action.But it has very strong osmosis to blade, can kill subepidermal insect, and the longevity of residure is long.It is ovicidal not.What its mechanism of action was different from general insecticide is that it disturbs neurophysiology movable, stimulate and discharge the r-aminobutyric acid, and the r-aminobutyric acid has inhibitory action to arthropodan nerve conduction, if paralysis symptom namely occurs after the mite class becomes mite and insect and larva and medicament contacts, inertia does not take food, and is dead after 2-4 days.Because not causing that insect dewaters rapidly, so its lethal effect is slower.But though predatism and parasite are had direct killing effect, because plant surface is residual few, therefore little to the damage of beneficial insect.Obvious to the root nematode effect.
Along with the sharp increase of world population, global range constantly improves the total demand of provand, and agricultural chemicals to stablizing the output of crops, has been brought into play important effect as the product of agricultural modernization.But, in recent years, a large amount of uses of high poison, persistent pesticide, the serious threat mankind's health, the food that residue of pesticide cause (comprising grain and gourd, fruit and vegetable) safety in production.And to environment and ecological destruction, become the people's livelihood problem of showing great attention to, and caused the attention of Government departments, strengthen the supervision of food safety production overall process, be an important measure.But this only takes stopgap measures, and solves the safety problem of food production, also needs to effect a permanent cure, and picks up from the source.
Limiting the use of and further forbid high-toxic pesticide is the trend in the whole world, is the needs of realizing agricultural and social sustainable development.In recent years, global various countries take new Pesticide Policies, particularly developed country very strict to the use restriction of high poison, persistent pesticide.On November 20th, 2002, official of European Union has issued EU Committee's 2076/2002 rules (seeing appendix 1).These rules and regulations: 320 kinds of agricultural chemicals that used on market, must cancel it as the license of plant protection articles for use before 25 days July in 2003, and stipulate to stop using before 31 days December in 2003.The proportion that China's high-toxic pesticide occupies is 70%, and the western developed country situation is opposite, approximately only accounts for 30%.The relevant department of the Chinese government has sent illegal instruction, completely forbids the use of high-toxic pesticide in agricultural production from 1 day January in 2007.Eliminate mercilessness to efficient, high malicious type pesticide species the domestic market, and the demand of the environmental protection type agricultural chemical of low toxicity, low-residual is with increasing.Development is efficient, safety, economy and guarantee that to replace the agricultural chemicals of high poison, high residue, to have become China's grain, melon dish are kept the safety in production and the task of top priority of food security with eco-friendly environment friendly agricultural.
For a long time, the pesticide original medicine of every liquid state and the solid-state former medicine of sizable solvability is arranged in organic solvent, no matter be insecticide, miticide, or bactericide or weed killer herbicide etc., be all that the form of making missible oil is used mostly, emulsifiable concentrates for agricultural chemicals is the important formulation of pesticidal preparations always, but owing to containing a large amount of inflammable organic solvents in missible oil, strict to aspects such as production, storing and uses, as miscarriage, operate not sternly, intoxicating phenomenon easily occurs or produce poisoning.Particularly in long-term use procedure, a large amount of organic solvents evaporate in atmosphere, environment has been caused seriously polluted, and all these problems have caused people's extensive concern.
Therefore, China's agricultural chemicals enterprise more selections on product of still needing that want to get through the close siege.At present, environment-protection pesticide is just meeting rare opportunity to develop, compares with chemical pesticide, and environment-protection pesticide has following advantage: (1) is easily degraded in environment, is lacked residual or noresidue people, animal, beneficial organism low toxicity, does not have environmental issue; (2) replace organic solvent as main carriers with water, little to eye irritation without unpleasant toxic odor without catching fire danger, reduced the pollution to environment, greatly improved the safety to production, storing and user; (3) have good heat storage stability, cold cut stability and water dilution stability; (4) agriculture is originally low, and with respect to chemical pesticide, profit space is larger; (5) energy savings.
But environment-protection pesticide insecticidal effect in the market is unsatisfactory.
Summary of the invention
