Abstract
The present invention relates to an acaricide composition whose effective component is a mixture of fenpropathrin and propargite with the weight ratio of 1:0.05-5, and the weight percentage content of its effective component is 1-80%. According to the requirements it can be made into the various dosage forms, such as emulsifiable concentrate, water agent and power agent. The tests show that it not only has the good acaricidal effect, but also can raise yield and quality of crops simultaneously.
Description
One, technical field:
The present invention relates to composition pesticide, the composition pesticide that kills acarid that uses on especially a kind of agricultural.
Two, background technology:
Acarid, the popular name two spotted spider mite is a kind of serious biology that endangers on agricultural, the conventional pesticide that is used at present preventing and treating very easily develops immunity to drugs owing to repeatedly using, and the control cost is also higher.
Fenpropathrin (fenpropethrin), chemical name: alpha-cyano-3-phenoxy benzyl ground, 2,3,3-tetramethyl-ring propane carbonyl acid ester, structural formula is:
This compound is a kind of pyrethroid Insecticidal and acaricidal agent, be unique medicament with acaricidal activity in such medicament, based on repellent action, it is littler that lethality is wanted to acarid for fenpropathrin, and can not use as independent miticide, mix with other miticide and use.
Alkynes mite spy (propargite), chemical name: 2-(4-tert-butyl benzene oxy) hexamethylene propyl group-2-alkynyl sulfite, structural formula is:
This compound is a kind of low toxicity broad spectrum activity organosulfur acaricide, all effective to becoming mite, young mite, mite ovum, using for many years in the whole world, non-resistant produces, but this agent cost is higher, and cotton and orange tender slightly all there is poisoning, the serious medicine fruit phenomenon that also can produce influences fruit quality, and the poisoning that overcomes alkynes mite spy is an important content in the agricultural production.
Three, summary of the invention:
The purpose of this invention is to provide a kind of composition pesticide, solve the pesticide cost height emphatically, poisoning is serious, problems such as drug effect difference.
Technical scheme of the present invention is: miticide farm chemical composition, active ingredient are the special mixture of fenpropathrin and alkynes mite.
Described active ingredient fenpropathrin and alkynes mite spy's weight ratio 1: 0.05～5, preferred weight ratio 1: 0.1～1.
Described miticide farm chemical composition, active ingredient weight percentage are 1～80%, preferred 10～50%.
The present invention can adopt general formulation method to be prepared into various formulations according to actual needs, as missible oil, aqua, pulvis, dried outstanding agent etc.
The adoptable surfactant of pesticidal preparations of the present invention has anionic surfactant and nonionic surface active agent.The aliphatic alcohol sulfate, alkylol polyoxyethylene groups ether sodium sulfate, the alkylol polyoxyethylene groups ether calcium sulphate that comprise Sulfates, the sodium alkyl sulfonate of Sulfonates, alkylbenzenesulfonate, fatty alcohol ethylene oxide adduct sulfonate, alkylphenol-polyethenoxy base ether.
Pesticidal preparations of the present invention can add anionic and other type auxiliary agent: alkyl phosphate and alkoxide thereof, fatty acid polyoxy alkane alkene ester phosphate and derivative thereof, alkyl aralkyl phenol, phosphite ester, ethylene oxide adduct ethers, glyceryl monostearate, dialkyl group succinate sulfonate, epoxidized vegetable oil, aminocarboxylic acid ester, hydroxycarboxylic acid esters.
Advantage of the present invention is: miticide farm chemical composition of the present invention, active ingredient is chosen fenpropathrin and alkynes mite spy, prescription rationally, fenpropathrin and alkynes mite spy are mixed by a certain percentage, can overcome two kinds of medicament deficiencies, promptly remedied serious, the high deficiency of the big control cost of consumption of the special poisoning of alkynes mite, also remedied the low deficiency of fenpropathrin acaricidal activity simultaneously, and significantly mite synergistic effect has extremely been arranged.The experiment proved that fast to the speed of knocking down of evil mite, the lasting period is long, when guaranteeing control efficiency, has also guaranteed output and the quality of crop, the needs of suitable current agricultural production have tangible using value and social benefit.
Four, embodiment:
The present invention is further illustrated below in conjunction with embodiment, but be not limited to embodiment.

Embodiment 2
Get the former medicine double centner of fenpropathrin, 50 kilograms of propargite medicines, respectively with blend after the xylene soluble in the enamel reaction still that has heater, add totally 80 kilograms in auxiliary agent epoxidized vegetable oil, emulsifier alkylol polyoxyethylene groups ether calcium sulphate again, stirring 1.5 hours below 50 ℃, add dimethylbenzene again and make it total amount and reach 77 kilograms, continue again to stir 2 hours, obtain homogeneous phase transparent missible oil.
Embodiment 3
Get the former medicine double centner of fenpropathrin, 20 kilograms of propargite medicines, respectively with blend after the xylene soluble in the enamel reaction still that has heater, 80 kilograms of sodium alkyl sulfonates that add the emulsifier Sulfonates again, stirred 1.5 hours down at 50 ℃, add dimethylbenzene again and make it total amount and reach 75 kilograms, continue again to stir 2 hours, obtain homogeneous phase transparent missible oil.
Virulence of the present invention and insecticidal effect see Table 1,2; With the citrus leaf-miner is target pest, uses the mixture determining lethality of the Imidacloprid of fenpropathrin and different proportion, and the field experiment data see Table 3.
