Abstract
A composite microemulsion for preventing and eliminating multiple kinds of pests and mites of agricultural crops including rice, vegetables, cotton, fruit trees, soybean, etc is prepared from Xiuchongjing, monosultap, cosolvent, deionized water, surfactant, defoaming agent and antifreezing agent. Its advantages are high effect and high safety to crops.
Description
The application is for dividing an application
The applying date of original application is: 09 month 06 day calendar year 2001
Application number is: 01128580.x
Denomination of invention is: contain micro-emulsion composition of insecticide chlorfenapyr or chlorfenapyr+desinsection list and preparation method thereof
Technical field:
The present invention relates to a kind of micro-emulsion composition that contains bromothalonil and monosultap.
Background technology:
Chlorfenapyr: chemical name is 4-bromo-2-rubigan-1-ethoxyl methyl-5-trifluoromethyl pyrpole-3-nitrile, and structural formula is:
Outward appearance is a faint yellow solid, it is a kind of Insecticidal and acaricidal agent of efficient, low toxicity, be widely used in various pests and mite class on the crops such as control paddy rice, vegetables, cotton, fruit tree, soybean, as the snout moth's larva of rice, tetranychid, leafhopper, purplish red short hairs mite, colorado potato beetles, noctuid, water diamond-back moth, cabbage caterpillar, cotton bollworm, aphid, mythimna separata, miller, caterpillar, leaf moth, codling moth, heart-eating worm, grape borer etc., the just harm of controlled various pests of a dispenser, and, can not produce poisoning to crop safety.American Cyanamid Company has applied for patent (patent No. 88106516.1) on July 28th, 1998 in China, this patent disclosure this compound and some compositions, but do not relate to microemulsion.
The desinsection list: chemical name is 2-N, N dimethylamine base-1-sodium thiosulfate base-3-propane thiosulfate, and structural formula is:
It is China's a kind of pesticide species of innovation and creation voluntarily.It is that a kind of broad spectrum disinfestation has strong stomach toxicity, tag and systemic action, and have concurrently stifling, ovicidal action, be widely used in the control paddy rice, corn, vegetables, fruit tree, the tea soybean, the multiple lepidoptera pest of crops such as sugarcane, to the rice grub pink rice borer, striped rice borer, paddy stem borer, leaf-roller, rice plant skipper, thrips, leafhopper, mythimna separata, scotellaris, plant hopper, the vegetable-crop pest-insect cabbage caterpillar, Oeobia undalis, striped flea-beetle, silver mosquito noctuid, dish leaf insect, the dish caterpillar, educate stinkbug, cicada in little, tie leaf miner mutually, tens kinds of insects such as rust wall wind have excellent control efficiency, secondly oncomelania and ovum are had special efficacy.The desinsection list has been developed many preparations, but does not see the report with the chlorfenapyr complex preparation.
Summary of the invention:
The purpose of this invention is to provide a kind of micro-emulsion composition that contains bromothalonil and monosultap.
Composition of the present invention is: chlorfenapyr is active ingredient 1%～5% (w/w), the desinsection list is active ingredient 10%～15% (w/w), surfactant 6%～15% (w/w), cosolvent 3%～7% (w/w), deionized water 21%～87% (w/w), defoamer 1%～2% (w/w), antifreeze 2%～5% (w/w).Active ingredient among the present invention is chlorfenapyr; The surfactant that uses among the present invention is anionic, nonionic or their mixed type, and DBSA base salt, lauryl sulfate, lignosulfonates, alkylphenol polyoxyethylene class, phenethyl phenol polyethenoxy ether, sorbitol polyoxyethylene ether, styryl phenol polyethenoxy polypropylene ether and alkyl benzene sulfonate calcium salt mixture etc. are arranged; The selected cosolvent of the present invention is aromatic hydrocarbon, heavy aromatic hydrocarbon, fatty alcohol, and preferred cosolvent is cyclohexanone, dimethyl formamide, acetone, dimethyl sulfoxide (DMSO), ethyl acetate, oxolane, dimethylbenzene etc.; The used continuous phase of the present invention is deionized water; The used defoamer of the present invention is n-butanol, n-octyl alcohol, dimethicone; The selected optional spent glycol of antifreeze of the present invention, propane diols, glycerine, polyethylene glycol, urea etc.
Preparation method of the present invention is: earlier with the former medicinal cosolvent dissolving of chlorfenapyr+desinsection list, add surfactant then, add the stronger surfactant of hydrophily earlier, add the stronger surfactant of lipophile after stirring again, stir, add defoamer again, stir and form homogeneous, transparent, stable microemulsion agent; The selected mixing speed of the present invention is 60 rev/mins～1700 rev/mins, and mixing time is 30 minutes～2 hours, and whipping temp is a normal temperature.
The present invention is mainly used in various pests and mite class on the crops such as paddy rice, vegetables, cotton, fruit tree, soybean, as the snout moth's larva of rice, tetranychid, leafhopper, purplish red short hairs mite, colorado potato beetles, noctuid, diamond-back moth, cabbage caterpillar, cotton bollworm, aphid, mythimna separata, miller, caterpillar, leaf moth, codling moth, heart-eating worm, grape borer etc., the just harm of controlled various pests of a dispenser, and, can not produce poisoning to crop safety.The present invention is owing to being to be continuous phase with the deionized water, and is with low cost, can reduce drug cost.In addition, cosolvent content of the present invention is low, has reduced environmental pollution, belongs to environment-friendly type novel pesticide preparation.
Embodiment:
The invention will be further described below in conjunction with embodiment and test of pesticide effectiveness example:
Embodiment 1-3
Chlorfenapyr+desinsection list (being designated hereinafter simply as bromine kills), cosolvent, water, surfactant, defoamer, antifreeze etc. are mixed with microemulsion, and it is as follows to fill a prescription:
Table 1
Test example 1:
Giving birth to the survey indoor bioassay result of portion through national agricultural chemicals initiative base, Hunan, center and show, 15% bromine worm is clear+and desinsection list microemulsion has good biologically active to leafhopper, diamond-back moth, cabbage caterpillar, cotton bollworm, aphid, mythimna separata etc., and it the results are shown in following table.
Table 2
