Abstract
The invention relates to a pesticide preparation, in particular to stable acephate abamectin missible oil. The stable acephate abamectin missible oil is prepared by mixing the following raw materials in percentage by weight: 1 to 40 percent of acephate, 0.1 to 5 percent of abamectin, 0.1 to 20 percent of stabilizing agent, 1 to 10 percent of emulsifying agent, and 25 to 97.8 percent of solvent. The stable acephate abamectin missible oil has the following advantages and beneficial effects: (1) the stable acephate abamectin missible oil improves the control effect on resistant pests, further enlarges the control spectrum to the pests, the suitable occasions and the serviceable range, and has excellent control effect on rice leaf rollers, striped rice borers, yellow rice borers, diamond back moths, cabbage worms, bemisia tabaci, prodenia litura, cotton bollworms, red spiders and the like; (2) the stable acephate abamectin missible oil has systemic properties and strong permeability, is long in lasting period and is environment-friendly; (3) a product of the stable acephate abamectin missible oil has high storage stability and a long guarantee period; and (4) the stable acephate abamectin missible oil reduces the used amount of the abamectin, the manufacturing cost and the use cost.
Description
Technical field
The present invention relates to a kind of pesticidal preparations, specifically a kind of stable acephate abamectin missible oil.
Background technology
Because the agricultural chemicals abuse makes insect more and more serious to the resistance that agricultural chemicals produces, and causes single pesticidal preparations pest control effect to reduce year by year.The composite conduct of insecticide delays one of effective means that insect develops immunity to drugs and comes into one's own just day by day.
Orthene is the good alternative kind of height organophosphorous pesticide, belongs to the lower toxicity broad-spectrum organic insecticide, has very strong interior suction, stomach toxicity and action of contace poison, and can kill ovum.The drug effect height, the lasting period was 15 days.Insecticidal spectrum is wide, can prevent and treat more than 100 kind of chewing type, sucking pest, evil mite, some lepidoptera pests are had concurrently certain fumigation action, be applicable to crop pest controls such as grain, cotton, oil, vegetables, fruit tree, tea, mulberry, beet, sugarcane, herbage, good especially to the rice fulgorid drug effect.Safety is good, and the half life period in plant tissue is 5～10 days, is 0.5～4 day in general soil, in clayed soil 6～13 days.Unicellular alga so that inanimate object enrichment phenomenon all in mammal and the bird body, to aquatic livestock safety such as fish.
Avermectin is a kind of ten hexa-atomic Macrocyclic lactone compounds that have desinsection, kill mite, eelworm-killing activity, is a kind of antibiotics novel agrochemical.Insecticidal spectrum is wide, is mainly used to prevent and treat pear sucker, cotten aphid etc. in China, the insect of leaf mining such as Americal rice leaf miner etc., evil mite such as Tetranychus urticae, tea orange tetranychid, tetranychus viennensis and the host is wide, feeding habits are assorted insect such as diamond-back moth etc.Insect and mite class had tag and stomach poison function and faint fumigation action is arranged.Blade is had very strong osmosis, can kill subepidermal insect, and the longevity of residure is long.Damage to beneficial insect is little.In soil, degraded inanimate object enrichment, environmental friendliness rapidly by microorganism.
The synergistic complex of agricultural chemicals is the effective measures that the expanding prevention spectrum improves preventive effect.Though it is existing many at present relevant with the report of orthene as the compounded preparation of pesticide of one of active component, but Shang Weiyou is with orthene and the two report as the Pesticidal combination registration listing of active component of Avermectin, the present invention establishes physicochemical property, processing technology, the synergy preventive and therapeutic effect of this novel mixture get off in a creative way, having solved the stability problem of active component, is a kind ofly good can effectively reduce applications of pesticide amount, delay the target organisms pesticide resistance, reduce the orthene of environmental pollution and the complex preparation of Avermectin.
Summary of the invention
Purpose of the present invention is exactly by the network analysis to orthene and abamectin pest killing characteristic, and both are composite according to certain ratio, obtains a kind of stable acephate abamectin missible oil.Antagonism insect of the present invention has better effect, and rice fir leaf roll snout moth's larva, striped rice borer, paddy stem borer, diamond-back moth, cabbage caterpillar, Bemisia tabaci, prodenia litura, cotton bollworm, two spotted spider mite etc. are all had excellent preventive effect.
The present invention is made up of the former medicine of orthene, the former medicine of Avermectin, solvent, emulsifier and stabilizing agent, and its each composition and percentage by weight thereof are:
Orthene 1～40%
Avermectin 0.1～5%
Emulsifier 1～10%
Stabilizing agent 0.1～20%
Solvent 25～97.8%.
Optimized technical scheme of the present invention is:
Orthene 20%
Avermectin 4%
Emulsifier 6%
Stabilizing agent 10%
Solvent 60%.
In the invention described above, described stabilizing agent be 2-expoxy propane, isopropyl alcohol, n-butanol, ethylene glycol, polyethylene glycol, propane diols, glycerine, turpentine oil, urea, antioxidant BHT, antioxidant BHA, DAA, acetone, cyclohexanone and stabilizing agent known in those skilled in the art any one or multiple, preferably urea, antioxidant BHT, antioxidant BHA, N-Methyl pyrrolidone, acetone or cyclohexanone.More preferably urea, antioxidant BHA and N-Methyl pyrrolidone were by weight 1: 1: 1 mixture.The adding stabilizing agent can increase the physics and the chemical stability of mixture.
Among the present invention, described emulsifier is any one or the multiple combination among emulsifier 500#, 600#, 700#, 1600#, phenolic ether emulsifier, fatty alcohol emulsifier and the emulsifier known in those skilled in the art.Described solvent is any one or multiple combination of methyl alcohol, ethanol, dimethyl formamide, dimethylacetylamide, methyl-sulfoxide and solvent known in those skilled in the art.
Preparation method of the present invention is dissolved in orthene and Avermectin in the solvent, drops into emulsifier then, stirs, and then drops into stabilizing agent, stirs, and promptly obtains acephate abamectin missible oil.
Advantage that the present invention has and beneficial effect: (1) the present invention has improved the preventive effect of antagonism insect, and has further enlarged control spectrum and the applicable situation and the scope of application to insect.Rice leaf roller, striped rice borer, paddy stem borer, diamond-back moth, cabbage caterpillar, Bemisia tabaci, prodenia litura, cotton bollworm, two spotted spider mite etc. all there is excellent preventive effect; (2) absorption and strong permeability in the present invention has concurrently, the lasting period is long, and is environmentally friendly; (3) product storage-stable of the present invention is good, long shelf-life; (4) the present invention has reduced the consumption of Avermectin, has reduced manufacturing cost and use cost, and market is acceptant, is beneficial to popularization; (5) production technology of the present invention is simple relatively, the simple easy operating of equipment.
