Description
Technical Field
The invention relates to the field of pesticides, and particularly relates to a dinotefuran oil suspending agent, and a preparation method and application thereof.
Background
Dinotefuran is a third-generation nicotine pesticide developed by Mitsui chemical company of Japan, has broad insecticidal spectrum, is an excitant of nicotine acetylcholine receptors, influences synapses of central nervous systems of insects through spinal nerve transmission, has contact poisoning and stomach poisoning effects, and has excellent systemic osmosis. The dinotefuran is very safe to mammals, birds and aquatic organisms, has no phytotoxicity to crops, can control various pests of hemiptera, lepidoptera, coleoptera, diptera, hymenoptera and the like, and has high control effect on brown planthopper, sogatella furcifera, laodelphax striatellus, empoasca midnight and the like.
Although dinotefuran has a strong control effect on various pests, dinotefuran belongs to a type of insoluble active ingredients, and has the solubility of only 40g/L in water at 25 ℃ and not very high in other low-medium polar solvents. Therefore, for the composition of the dinotefuran insoluble active ingredient or the dinotefuran insoluble active ingredient and other agricultural chemicals, the dispersible oil suspending agent is generally selected to be prepared to improve the utilization rate of the active ingredient so as to achieve the synergistic effect, wherein the dispersible oil suspending agent is a high-dispersion stable suspension system taking a non-aqueous system as a dispersion medium, and is a dosage form taking oils which can be used as a synergistic auxiliary agent through tests and do not pollute crops as a dilution carrier, and the oils comprise vegetable oil and derivatives thereof or mineral oil and the like.
CN106359440A discloses a dinotefuran dispersible oil suspending agent, wherein the contents of each component are as follows: 20-30% of dinotefuran, 4-6% of octylphenol polyoxyethylene ether, 4-6% of calcium dodecyl benzene sulfonate, 4-6% of phenethyl phenyl propyl phenol polyoxyethylene ether, 0.8-1.2% of organic bentonite, 0.8-1.2% of white carbon black, 0.1-0.5% of citric acid, 0.1-0.5% of bihydrogenated tallow phthalic diamide, 0.1-0.5% of tris (2, 4-di-tert-butyl-phenyl) phosphite, 0.1-0.5% of 2-n-octyl-4-isothiazoline-3-ketone, 0.1-0.5% of HT-508 organosilicon, 18-22% of soybean oil and the balance of methyl oleate; the oil suspending agent solves the problems of oil separation, layering, caking, high decomposition rate, unstable chemistry and the like in the dinotefuran preparation, but the oil suspending agent still has low control effect on pests and is difficult to fully exert the activity of the dinotefuran.
CN109169646A discloses a preparation method of dinotefuran oil suspending agent, which aims to solve the technical problems of large particle size of dinotefuran particles, low drug effect, mechanical impurities and the like in the preparation obtained by the existing preparation process, but the diameter of emulsion droplets is controlled by stirring in the preparation method, the repetition rate of the method is low, and the large-scale production is difficult.
CN101784184B discloses a structural formula of R-O- (EO)w-(PO)x-(EO)y(PO)xThe compound of-H is used as a synergist of a neonicotinoid compound, particularly acetamiprid, and the composition has certain effect of increasing the control effect under the condition of specific solvent combination, but the synergistic effect is still low.
In summary, the oil suspending agent containing dinotefuran in the prior art has synergistic effect compared with other formulations of dinotefuran, but is still not ideal. Therefore, it is very necessary to find a synergistic auxiliary agent suitable for the dinotefuran oil suspending agent and further improve the dinotefuran activity.
