Abstract
The invention discloses a high-efficiency phenthoate emulsion in water, which is characterized by consisting of the following components in percentage by weight: 1 to 60 percent of phenthoate, 1 to 20 percent of solvent, 1 to 20 percent of surfactant, 1 to 5 percent of antifreeze agent, 0.1 to 3 percent of thickening agent, 0.1 to 0.5 percent of defoaming agent and 20 to 90 percent of water. In the invention, the water replaces most organic solvent, so the high-efficiency phenthoate emulsion in water is safe to use, and also can reduce the environmental pollution. Experiments of pharmacology prove that the control effect of the high-efficiency phenthoate emulsion in water is equivalent to that of cream containing the same active ingredients.
Description
Technical field
The present invention relates to a kind of composition and method of making the same that contains insecticide phenthoate dimephenthoate cidial aqueous emulsion, belong to field of agrochemicals.
Background technology
For a long time, because a large amount of chemical pesticides that use, this formulation of missible oil particularly, solvent major part in the product is compound fragrant hydrocarbons such as benzene,toluene,xylene, long-term use year after year, not only seriously caused the wasting of resources but also environment, ecology and food security have all been caused serious harm, human health has been constituted certain threat.Therefore, exploitation is useful to ecology, environment, replaces traditional organic solvent to make a class novel form of solvent with water, more and more is subjected to must looking of people.Its chemical name of phenthoate dimephenthoate cidial: O, O-dimethyl-S-(α-ethoxy carbonyl benzyl) phosphorodithioate.Physicochemical property: clear crystal (former medicine is that blush arrives yellow oil), fusing point 17-18 ℃, vapour pressure 5.3mPa (40 ℃), density 1.226 (20 ℃), Kow4900, solvability water 11mg/L (industrial goods 200mg/L, 20 ℃) is dissolved in methyl alcohol, ethanol, acetone, hexane, dimethylbenzene, cyclohexanol, benzene, carbon tetrachloride, carbon disulphide, dioxanes etc., 1,2-dioxy base hexane＞200, hexane 120, gasoline 100-170 (g/L, 2 ℃), pH3.9,5.8, preservation in 7.8 o'clock were slightly decomposed in 20 days, and pH9.7 preserves had 25% to decompose flash-point 165-170 ℃ in 20 days.Toxicity:,, belong to medium malicious class agricultural chemicals by China's toxicity category through skin LD502100mg/kg to big white mouse acute oral LD50300-400mg/kg.Eyes and skin irritation: skin is had slight stimulation, generally can not cause general toxicity.Under test dose, animal there is not carcinogenic, teratogenesis mutagenesis.
Phenthoate dimephenthoate cidial is applicable on the crops such as paddy rice, cotton, fruit tree, vegetables.Can be used for preventing and treating striped rice borer, paddy stem borer, rice fulgorid, scotellaris, cotton bollworm, aphid, leafhopper, cabbage caterpillar, diamond-back moth, prodenia litura, leaf roller, scale insect, heart-eating worm, oranges and tangerines arrowhead scales, brown round a red-spotted lizard, Aleurocanthus spiniferus, oranges and tangerines thrips, insects such as phyllocnistis citrella stainton.Its mechanism of action is for suppressing the acetylcholinesterase in the insect bodies.The formulation of this insecticide phenthoate dimephenthoate cidial, affects to environment owing to contain a large amount of organic solvents in the product based on 50% missible oil at present.
