Abstract
The present invention discloses a microemulsion composition containing insecticide chlorfenapyr and thiosultap sodium. Microemulsion is prepared from the chlorfenapyr, the thiosultap sodium, cosolvent, deionized water, surface active agents, defoaming agents and antifreezing agents. The present invention is directly used for preventing and curing various pests and mites, such as rice stem borers, spider mites, leaf hoppers, brevipalpus phoenicis, leptinotarsa decemlineata, nocturnal moths, diamondback moths, cabbage worms, cotton bollworms, aphids, armyworms, millers, caterpillars, leaf moths, codeine moths, fruit borers, grapes borers, etc., on crops, such as rice, vegetables, cotton, fruit trees, soybeans, etc.; single medicine application can control the damage of various pests, and the present invention is safe for the crops and does not generate phytotoxicity. Because water is used for substituting organic solvent in the microemulsion composition containing the chlorfenapyr and the thiosultap sodium, the energy is saved, and simultaneously, the environment is protected.
Description
The application is divisional application
The applying date of original application are as follows: on 09 06th, 2001
Application No. is: 01128580.x
Denomination of invention are as follows: containing insecticide chlorfenapyr or chlorfenapyr+Cupric sulfate micro-emulsion composition and
Preparation method
Technical field:
The present invention relates to a kind of micro-emulsion compositions containing bromothalonil and monosultap.
Background technique:
Chlorfenapyr: chemical name is the bromo- 2- rubigan -1- ethoxyl methyl -5- trifluoromethyl pyrpole -3- nitrile of 4-, and structural formula is:
Appearance is faint yellow solid, it is a kind of Insecticidal and acaricidal agent efficiently, less toxic, it is widely used in various pests and mite class on the crops such as prevention and treatment rice, vegetables, cotton, fruit tree, soybean, such as snout moth's larva of rice, tetranychid, leafhopper, purplish red short hairs mite, colorado potato beetles, noctuid, water diamond-back moth, cabbage caterpillar, bollworm, aphid, mythimna separata, miller, caterpillar, leaf moth, carpocapsa pononella, heart-eating worm, grape borer, primary application can control the harm of various pests, and to crop safety, phytotoxicity will not be generated.American Cyanamid Company has applied for patent (patent No. 88106516.1) in China on July 28th, 1998, and which disclose the compound and some compositions, but are not directed to microemulsion.
Cupric sulfate: chemical name 2-N, TMSDMA N dimethylamine base -1- sodium thiosulfate base -3- propane thiosulfate, structural formula are as follows:
It is a kind of pesticide species of China's voluntarily innovation and creation.It is that a kind of broad spectrum disinfestation has strong stomach toxicity, tag and systemic action, and it has concurrently stifling, ovicidal action, it is widely used in prevention and treatment rice, corn, vegetables, fruit tree, tea soybean, a variety of lepidoptera pests of the crops such as sugarcane, to rice grub pink rice borer, striped rice borer, yellow rice borer, leaf-roller, rice plant skipper, thrips, leafhopper, mythimna separata, scotellaris, plant hopper, vegetable-crop pest-insect cabbage caterpillar, Oeobia undalis, striped flea-beetle, silver-colored mosquito noctuid, dish leaf pest, dish caterpillar, educate stinkbug, small middle cicada, mutually knot leaf miner, tens kinds of pests such as rust wall wind have excellent control efficiency, secondly there is special efficacy to oncomelania and ovum.Cupric sulfate has developed many preparations, but has no the report with chlorfenapyr compound preparation.
The object of the present invention is to provide a kind of micro-emulsion compositions containing bromothalonil and monosultap.
Composition of the invention is: chlorfenapyr is effective component 1%~5% (w/w), Cupric sulfate is effective component 10%~15% (w/w), surfactant 6%~15% (w/w), cosolvent 3%~7% (w/w), deionized water 21%~87% (w/w), defoaming agent 1%~2% (w/w), antifreeze 2%~5% (w/w).Effective component in the present invention is chlorfenapyr；Surfactant used in the present invention is anionic, non-ionic or their mixed type, dodecyl benzene sulfonic acid base salt, lauryl sulfate, lignosulfonates, alkyl polyoxyethylene ether phosphate, agriculture breast 500, agricultural emulsifier NO.600, peaceful cream No. 100, NP-10, NP-15, NP-20, BY140, No. 1600, No. 1601, No. 1602, sorbitol polyoxyethylene ether, 0204C, 0206B；Cosolvent selected by the present invention is aromatic hydrocarbon, weight aromatic hydrocarbon, fatty alcohol, and preferred cosolvent is cyclohexanone, dimethylformamide, acetone, dimethyl sulfoxide, ethyl acetate, tetrahydrofuran, dimethylbenzene etc.；Water used in the present invention is deionized water；Defoaming agent used in the present invention is n-butanol, n-octyl alcohol, dimethicone；The optional spent glycol of antifreeze selected by the present invention, propylene glycol, glycerol, polyethylene glycol, urea etc..
The preparation method is that: first chlorfenapyr+Cupric sulfate original acceptable co-solvents are dissolved, then surfactant is added, first plus the stronger surfactant of hydrophily, lipophilic stronger surfactant is added after stirring, it stirs evenly, defoaming agent is added, stirring forms uniform, transparent, stable microemulsion；The selected mixing speed of the present invention is 60 revs/min~1700 revs/min, and mixing time is 30 minutes~2 hours, and whipping temp is room temperature.
Present invention is mainly used for various pests and mite class on the crops such as rice, vegetables, cotton, fruit tree, soybean, such as snout moth's larva of rice, tetranychid, leafhopper, purplish red short hairs mite, colorado potato beetles, noctuid, diamondback moth, cabbage caterpillar, bollworm, aphid, mythimna separata, miller, caterpillar, leaf moth, carpocapsa pononella, heart-eating worm, grape borer, primary application can control the harm of various pests, and to crop safety, phytotoxicity will not be generated.The present invention due to be using deionized water as continuous phase, it is low in cost, drug cost can be reduced.In addition, hydrotropy agent content of the present invention is low, reduce environmental pollution, belongs to environment-friendly type novel pesticide preparation.
