The present invention will be described in further detail with reference to specific embodiments.
Example 1
The embodiment provides a low-volatility coated insecticidal abamectin composition which comprises 5 parts of abamectin, 10 parts of DMF (dimethyl formamide), 20 parts of xylene, 10 parts of ethylene glycol and 15 parts of diisooctyl succinate sodium sulfonate in parts by mass.
Abamectin (CAS number: 71751-41-2) is a widely used agricultural or veterinary bactericide, insecticide and acaricide. Also known as ametidine. The avermectin is a sixteen-element macrolide compound with the activities of sterilization, disinsection, acaricidal and nematicidal, which is firstly developed by Dacun Zhi and the like of North university of Japan and Merck company of America, and is produced by fermenting Streptomyces avermitilis in Streptomyces avermitilis.
The action mechanism of the abamectin is different from that of common pesticides, the abamectin interferes with the neurophysiological activity and stimulates the release of gamma-aminobutyric acid, and the gamma-aminobutyric acid has an inhibiting effect on nerve conduction. After the mite imagoes, nymphs and insect larvae are contacted with the abamectin, paralysis symptoms appear, and the mites die after 2 to 4 days without eating or eating. However, the action mechanism of abamectin is not to cause rapid dehydration of insects, so that the lethal effect of abamectin is slow, and the insecticidal effect needs to be further improved.
DMF, N-dimethylformamide (CAS number: 68-12-2), which is a colorless transparent liquid, is a widely used chemical raw material and a widely used excellent solvent. Except for the halogenated hydrocarbon, can be optionally mixed with water and most organic solvents. Has good dissolving capacity and chemical stability for various organic compounds and inorganic compounds.
Xylene is a colorless transparent liquid; is a product in which two hydrogens on a benzene ring are substituted by methyl groups, and there are three isomers of o-xylene, m-xylene and p-xylene, and in the present invention, xylene means a mixture of the above isomers.
Ethylene glycol (CAS number: 107-21-1), also known as "ethylene glycol" or "1, 2-ethylene glycol", EG for short. Has a chemical formula of (CH)2OH)2Is the simplest diol. The ethylene glycol is colorless, odorless and sweetThe liquid, glycol, is miscible with water and acetone, but has low solubility in ethers. It is generally used as a solvent, an antifreeze and a raw material for synthesizing terylene.
Sodium diisooctyl succinate sulfonate (CAS number: 107-21-1) is off-white or yellowish powder and is easily soluble in water. Is stable to acid, alkali and hard water. The solid is heated to 110 deg.C, and then is carbonized without melting, and alkaline steam is released. The anionic surfactant has excellent penetrability and emulsifying foamability. The insecticidal composition can dissolve a wax layer on the body surface of pests, accelerate dehydration death of the pests and play a good role in supplementing the insecticidal effect of abamectin.
When the abamectin composition provided by the invention is used, a pesticide formulation commonly used in the prior art can be prepared, such as an emulsifiable concentrate, a suspending agent, an aqueous emulsion, a microemulsion or a water dispersible granule, but preferably, the abamectin composition is an emulsifiable concentrate, and after the abamectin composition is prepared into the emulsifiable concentrate, the excellent adhesiveness of the composition can be better exerted, the mobility of pests can be limited, then the film is formed to wrap the pests, the air valves are closed, the breathing is inhibited, the asphyxiation death of the pests is promoted, and the insecticidal effect of the abamectin composition is further improved.
