Abstract
The miticide and pesticide composition containing dimethyl disulfide as one kind of pesticide consists of dimethyl disulfide 0.1-15 wt%, emulsifier 3-20 wt%, and solvent 65-95 wt%; or consists of dimethyl disulfide 0.1-15 wt%, effective component A 0.1-40 wt%, emulsifier 5.0-20 wt%, and solvent 40-90 wt%. The effective component A is at least one of abamectin, pyridaben, diafenthiron, propargite and dicofol; the emulsifier is calcium alkyl benzene sulfonate, polyoxyethylene fatty ester, etc; and the solvent is biodiesel oil, xylene, methanol, etc. The miticide and pesticide composition has the features of high safety, low toxicity, less residue, low cost, high efficiency and broad pesticidal spectrum, and may be used in preventing and controlling mites of crop.
Description
Technical field
The present invention relates to agricultural chemicals, specifically be meant the agricultural insecticide and acaricide that contains dimethyl disulfide.
Background technology
Because the generation of pest resistance to insecticide problem causes most of pesticide species preventive effects to descend, rampant again phenomenon takes place in insect at present.And the mite class is that resistance forms the fastest in the various insects, at present to prevent and treat harmful mite effect preferably kind mainly be pyridaben, dicofol etc., but because each manufacturer's exploitation in recent years contains the single agent or the mixture preparation of these medicaments in a large number, adding that the peasant continuously uses this medicament list agent and do not rotate use with other kinds for many years, causing the evil mite that it has been produced pesticide resistance.Originally the highly effective pesticide kind that was applied on the harmful mite is just considerably less, adds drug-fast generation, and the miticide of existing market coideal is very few.Therefore, the active demand that research and development are novel, efficient miticide has become agricultural production, and along with the reinforcement day by day of people's environmental consciousness, then becomes the direction of agricultural chemicals development from now on eco-friendly pesticide species at low toxicity, noresidue.
Summary of the invention
The technical problem to be solved in the present invention is, defective at the prior art existence, a kind of agricultural insecticide and acaricide that contains dimethyl disulfide is proposed, it has safety, low toxicity, low-residual, low cost and characteristics efficient, wide spectrum, control efficiency is better than other miticides, can effectively prevent and treat the multiple harmful mite of various crop, the pesticide resistance that delays insect evil mite produces.
One of technical solution of the present invention is that the described percentage by weight that contains the agricultural insecticide and acaricide of dimethyl disulfide consists of:
Dimethyl disulfide 0.1%-15%,
Emulsifier 3%-20%,
Solvent 65%-95%.
Two of technical solution of the present invention is that the described percentage by weight that contains the agricultural insecticide and acaricide of dimethyl disulfide consists of:
Dimethyl disulfide 0.1%-15%,
Effective constituents A: 0.1%-40%,
Emulsifier: 5.0%-20%,
Solvent: 40%-90%.
Below the present invention made further specify.
Among the present invention, described dimethyl disulfide has another name called Methyl disulfide, methyl disulfide, curing dimethyl.Past is mainly as solvent, pesticide intermediate and spices etc.; Development person of the present invention uses it for described agricultural chemicals and belongs to low toxicity, and acute oral LD50 is 2320mg/kg, and acute is 10000mg/kg through skin LD50, is that the vegetalitas that contains plurality of active ingredients is killed mite, insecticide, and the mode of action is stomach toxicity and tags; A large number of experiments show that it has preventive effect preferably to various harmful mites such as cotton red spider, citrus red mites.
Described effective constituents A is any one or more mixtures formed with arbitrary proportion in Avermectin, pyridaben, methamidophos, alkynes mite spy, the dicofol.
Described emulsifier mainly is selected from any one or more mixtures formed with arbitrary proportion in alkyl benzene calcium sulfonate, polyoxyethylene carboxylate, sorbitan fatty acid ester, fatty alcohol-polyoxyethylene ether, castor oil polyoxyethylene ether, the polyoxyethylene nonylphenol ether.
Described solvent mainly is selected from any one or more mixtures formed with arbitrary proportion in biodiesel, dimethylbenzene, methyl alcohol, ethanol, dimethyl formamide, methyl-sulfoxide, solvent naphtha, the vegetable oil.Wherein, described biodiesel formal name used at school fatty acid methyl ester or fatty-acid ethyl ester, be that to utilize animal and plant fat, acidifying oil, waste oil, swill oil, grease factory oil foot, soap stock etc. be raw material, make the renewable energy resources of " safety, cleaning, efficient " through reaction, organic solvents such as it and all kinds of pesticide original medicine and dimethylbenzene, methyl alcohol have compatibility preferably.
The present invention learns through a large amount of tests, as the Avermectin of conventional agent for killing mite and pest or pyridaben, methamidophos, alkynes mite spy, dicofol, with dimethyl disulfide composite after, can significantly delay the generation of pest resistance to insecticide, improve effect of chemical control.
Several chemical control citrus red mite tests of pesticide effectiveness of composition of the present invention and prior art the results are shown in following table 1.
Table 1
Illustrate: in the table 1, A liquid is 10% pyridaben missible oil, and B liquid is 10.5% A Wei pyridaben missible oil, and C liquid contains the missible oil of 2.5% A Wei and dimethyl disulfide for the present invention.
Dimethyl disulfide and the abamectin compounded usage amount that not only reduces pesticide active ingredient reduce its pollution to environment and destroy as can be seen from Table 1; Also improved simultaneously drug effect, significant otherness has been arranged with medicament pyridaben at present commonly used and complex preparation thereof; The pesticide resistance that has delayed insect evil mite when improving drug effect produces.
As known from the above, the present invention is a kind of agricultural insecticide and acaricide that contains dimethyl disulfide, characteristics with safety, low toxicity, low-residual, dimethyl disulfide is after blade absorbs, mainly concentrate on the epidermal cell internal layer, under the situation of sunlight direct projection, can accelerated decomposition, after decomposing, promptly do not have remaining after 10 days; And it has efficiently, the characteristics of wide spectrum, can prevent and treat the multiple harmful mite of fruit tree, vegetables, cotton various crop, and control efficiency is better than other miticides.
