Abstract
The invention discloses a pesticide / acaricide drug composition which is characterized by comprising the following ingredients by weight: 5 to 70 percent of aqueous oleate, 0.05 to 60 percent of abamectin drug or abamectin derivatives, 3 to 50 percent of surface active agent, 0 to 30 percent of stabilizing agent or synergistic agent, 0 to 5 percent of osmotic agent, 0 to 85 percent of water or organic solvent, 0 to 30 percent of plant regulator and 0 to 50 percent of mineral salt. The drug composition can enhance the prevention effect of AVMS, decrease the effective consumption of the AVMS, restrain the resistance of organisms and lessen the vegetable remains and environmental pollution.
Description
Technical field
The present invention relates to the Avermectin biological insecticides, specifically a kind of Disinsection/miticide pharmaceutical composition with synergistic effect.
Background technology
Avermectins medicine (Avermectins, AVMS) belong to macrolide antibiotics, it acts on the GABAA acceptor of insect neuron cynapse or neuromuscular synapse, the information transmission of nerve endings in the interference insect body, excite nerve not the tip emit neurotransmission inhibitor γ-aminobutyric acid (GA-BA), impel the chloride channel of GABA gate to extend open, chloride channel is had to activation, a large amount of chlorions pour in and cause the hyperpolarization of neu current potential, cause neu in holddown, thereby block nerves is contacting of the tip and muscle not, make the insect paralysis, food refusal, dead.It all has very strong inhibitory or killing effect to most parasitic nematodes and arthropods.Prevent and treat that polypide is little, from generation to generation many, the insect that is prone to drug-fast insect (as pear sucker, cotten aphid etc.), leaf mining (as Americal rice leaf miner etc.), evil mite (as Tetranychus urticae, the orange tetranychid of tea, tetranychus viennensis) and the host is wide, feeding habits are assorted insect (as diamond-back moth etc.) China is multiplex.The AVMS produce effects is slow, therefore in use, usually is difficult to hold its effective usage amount.And in actual applications, consumption is too high or too low all can cause serious adverse consequences.As when drug concentration is too high, be not only to cause cost to rise, more seriously AVMS has very strong osmosis to plant, and the longevity of residure is long.
It is high residue in agricultural product, animal derived food, can cause certain harm to human body.Therefore China's uses of having limited the quantity of, and will detect the residual quantity of Avermectins medicine in agricultural and veterinary chemicals and classify residual monitoring emphasis (the Chinese Ministry of Agriculture announces file No. 235 referring in December, 2002) as; When drug concentration during lower than effective dose, weak effect not only, and can directly cause organism to develop immunity to drugs.At present relevant organism has many reports to resistance and the resistance mechanism of AVMS.At first Scott in 1980 and Geoghiou have found that indoor the eliminating of anti-chrysanthemum ester class select housefly strain (LPR) AVMS to be had to the cross resistance of 7.6 times, rear research shows that this phenomenon is that metabolism enhancing and cuticular penetration reduction due to mixed-functional oxidase (MFO) causes, and being reduced to main resistance mechanism with cuticular penetration, is height recessive inheritance.Gampos in 1991 and Dybas find that Tetranychus urticae has resistance to AVMS, and its resistance is also relevant with cuticular penetration and oxidative metabolism, and Tetranychus urticae is the incomplete recessive inheritance of autosome to resistance development and administration time length, its genetics of resistance of AVMS.Li Tengwu etc. carry out resistance seed selection research to diamond-back moth and find, diamond-back moth is also the incomplete recessive inheritance of autosome to the genetics of resistance of AVMS.Argentine and Clark have found the resistance of colorado potato beetle to AVMS, and its mechanism is also relevant with mixed-functional oxidase and carboxy-lesterase, and its genetics of resistance and diamond-back moth and Tetranychus urticae have similarity, are also the incomplete recessive inheritance of autosome.Find that in addition Liriomyza trifolii, diamond-back moth, Cockroach population have certain resistance to AVMS.In actual applications, for suppressing as much as possible organism, AVMS pesticide resistance people are adopted to following methods usually: (1) takes food after the AVMS biopesticide for insect not the eating of 1-3d, motionless, not dead poisoning process, the optimum period medication, to reach control efficiency preferably.(2) with other agricultural chemicals rotation medications, delay the generation of its resistance.(3) increase oxidase inhibitor Pbo or esterase inhibitor DEF in pharmaceutical composition, to improve control efficiency, suppress resistance.Although said method has suppressed the generation of resistance to a certain extent, does not tackle the problem at its root.And change other agricultural chemicals or add oxidase inhibitor Pbo or esterase inhibitor DEF, be unfavorable for that equally people's is healthy.
Summary of the invention
Purpose of the present invention just is to provide a kind of Disinsection/miticide pharmaceutical composition, and this pharmaceutical composition can strengthen the control efficiency of AVMS, reduces the effective dose of AVMS, suppresses the generation of organism resistance, reduces the residual and environmental pollution of plant.
The present invention seeks to realize like this:
The present invention is directed to existing Avermectins agricultural chemicals onset and slowly, easily produce the shortcoming of resistance, the repeated screening test, invented a kind of new Disinsection/miticide pharmaceutical composition thus.Have good synergy in said composition between each component, it had both strengthened the epidermal cell infiltration of agricultural chemicals to crop and insect, had also weakened volatilization and the oxidation of agricultural chemicals, also on polypide, formed oil film simultaneously, and sealing insect body surface tidal air hole, suffocate it.Thereby effectively improved preventive effect, extended effective drug duration, delayed the resistance generation.
Pharmaceutical composition of the present invention includes the component of following percentage by weight: unthickened fuel acid esters 5～70%, Avermectins medicine or avermectin derivatives 0.05～60%, surfactant 3～50%, stabilizing agent or synergist 0～30%, bleeding agent 0～5%, water or organic solvent 0～85%, plant modifying agent 0～30% and mineral salt 3～50%.
Avermectins medicine in the present composition refers to the following agricultural chemicals that comprises one or more: Avermectin and avermectin derivatives (as Affirm (Merck Co.) benzoic acid or ester, emamectin-benzoate, acetylamino evericin, ivermectin, doramectin, salad rhzomorph).These Avermectin series of products all are commercially available.
Its preferred component and percentage by weight are: unthickened fuel acid esters 25～70%, Avermectins medicine 0.05～30%, surfactant 3～20%, bleeding agent 0～5%, water or organic solvent 0～55%.
