Abstract

The invention discloses an L-terpineol synergist-containing and beta-cypermethrin-containing synergistic pesticide composition, which is characterized in that: the pesticide composition consists of an active ingredient, a synergist and auxiliary materials, wherein the active ingredient is the beta-cypermethrin; and the synergist is the L-terpineol. The composition can overcome resistance of sanitary pests to the beta-cypermethrin, improves pesticide effect, reduces pesticide dosage, retards pesticide resistance of the pests and has less damage and pollution to ecological environment.

Description

The beta-cypermethrin pesticide composition that contains L-terpineol synergist
Technical field:
The present invention relates to a kind of insecticides, the insecticides that to be specifically related to take beta-cypermethrin be active ingredient.
Technical background:
L-terpineol, also claims terpineol, has α, β, tri-kinds of isomer of γ, Shi You Chemical Industry Inst., Guangxi Zhuang Autonomous Region synthetic a kind of chemical products in 2002, have good deodorize, moistening and infiltration capacity.From 2003 to the present, Guangxi Chemical Inst. has carried out its synergistic activity research to various agricultural chemicals.Research shows, L-terpineol all shows certain synergistic effect to various bactericide and insecticide.Specifically see Chinese Patent Application No.: 03178548.4 open (bulletin) number: patentee: Chemical Industry Inst., Guangxi Zhuang Autonomous Region, inventor: Huang Kelin, Fan Xiaodan, Wang Guiying, Long Yuyan, this invention provide a kind of take containing australene, be that main turpentine oil is raw material, take low-carbon alcohols or ketone as solvent, adopting modification strongly acidic styrene type cation exchange resin is catalyzer, by fixed bed reactors, carry out catalysis hydration reaction, the method of one-step synthesis levogyrate alpha-terpineol, the weight ratio of catalyzer and australene is 1: 1~10, the mol ratio of australene and water is 1: 1.1~2, the mol ratio of water and solvent is 1: 0.1~0.9, reaction temperature is 70~100 ℃, reaction time is 5~13 hours, australene conversion ratio is more than 95%, levogyrate alpha-terpineol yield is more than 65%.
Beta-cypermethrin (beta-cypermethrin), beta-cypermethrin is a kind of pyrethroid insecticides, mainly by interacting and destroyed neural function with insect sodium channel.Biologically active is higher, is the efficient isomer of cypermethrin, has and tags and stomach poison function.Insecticidal spectrum is wide, the speed of knocking down is fast, and insecticidal activity is high compared with cypermethrin.Be applicable to prevent and treat insect and the sanitary insect pest in the various plants such as cotton, vegetables, fruit tree, tea tree, forest.
Yet through application for many years, some sanitary insect pests have produced certain resistance to beta-cypermethrin.The preventive effect of this medicine is more and more lower, and working concentration is just more and more higher, has caused the pollution of environment.For the insect of easy generation resistance, a kind of method be exploitation new with the new component of existing product without cross resistance.But the development cost of new active ingredient is high, and the cycle is long, and be unable to catch up with the speed that insect produces resistance.
The active ingredient of different cultivars is carried out composite, is to delay the better more common method that insect produces resistance.Also having another kind of method is to add synergist for the active ingredient that insect has produced resistance to it.Thereby greatly delay insect, producing resistance, extended the life-span of pesticide active ingredient, is a kind of important means of integrated control insect.Synergist using L-terpineol as beta-cypermethrin there is no people and reported.
Summary of the invention:
Main purpose of the present invention is that research has the best synergy proportioning of the L-terpineol of synergistic effect to it to beta-cypermethrin, to solve some sanitary insect pests, this medicine is produced to the problem of resistance, reduces its dosage, protection of the environment.
Technical scheme of the present invention is:
A kind of Synergistic insecticidal composition that contains L-terpineol and beta-cypermethrin, it is characterized in that: this insecticides is comprised of active ingredient, synergist and auxiliary material, described active ingredient is beta-cypermethrin, synergist is L-terpineol, and it can be missible oil, microemulsion, suspending agent, aqueous emulsion, propellant, aerosol and thermal fog that said composition is divided according to formulations of pesticide product.
Synergistic insecticidal composition active ingredient---beta-cypermethrin percentage by weight is 0.1%~20%, synergist---L-terpineol percentage by weight is 3%~15%.
Synergistic insecticidal composition of the present invention is by active ingredient beta-cypermethrin and synergist L-terpineol and auxiliary agent and carrier is composite forms.Wherein conventional auxiliary agent is as neopelex, calcium dodecyl benzene sulfonate, lauryl sodium sulfate, alkyl phenol formaldehyde resin polyoxyethylene ether, aliphatic alcohol sulfate, phenethyl phenol polyethenoxy ether, Nonyl pheno base ether, lignosulfonates, alkylbenzenesulfonate, alkylphenol polyoxyethylene, polyoxyethylene nonylphenol ether, alkyl ethyl sulfonate, alkylnaphthalene sulfonate formaldehyde condensation products and polycarboxylic acid, triethanolamine oleate or epoxidized vegetable oil are as epoxidized linseed, epoxidized soybean oil, toluene, dimethylbenzene, acetone, cyclohexanone, ethanol, deodorized kerosine, essence, deionized water, dimethyl ether, Compressed Gas or hydrocarbon compound are as propane, iso-butane, isopentane and composition thereof.
Insecticides provided by the present invention has the following advantages:
L-terpineol shows unique characteristics at aspects such as agriculture desinsection, sterilization and pesticide synergistic, mosquito repellents.Aspect domestic hygiene, L-terpineol has stronger mosquito repellent effect, and the germ of some harm humans health is also had to killing action.Because L-terpineol has no side effect to human body, will become a kind of novel green agricultural chemicals and domestic hygiene disinfectant, there is very large market potential, will produce good economy, society and environmental benefit.
By L-terpineol and efficient cypermethrin compounded, can overcome the resistance that sanitary insect pest produces beta-cypermethrin, improve drug effect, reduce the pesticide resistance that dosage delays insect, to the infringement of ecotope and less pollution.
