Abstract
The present invention relates to a pesticide composition with systemic action, its effective component is a mixture of fenpropathrin and imidacloprid, their weight ratio of 1:0.05-10, the weight percentage of effective component mixture is 1-80%. According to the requirements it can be made into emulsifiable concentrate, water agent, powder agent and other pesticide dosage forms. Said invention can greatly reduce insecticide burn, and is an ideal pesticide composition instead of high-toxicity pesticide omethoate.
Description
One, technical field:
What the present invention relates to is agricultural chemical insecticide, particularly a kind of insecticides with systemic action.
Two, background technology:
For agricultural production, agricultural chemicals is indispensable, but because some insecticide variety toxicity is big, the residence time long, dangerous to human and environment, use is easy to generate problem such as resistance repeatedly in a large number, need constantly to change new varieties, systemic insecticide flolimat commonly used at present is exactly the kind that state plan limits the use of.
Fenpropathrin (fenpropethrin), chemical name: alpha-cyano-3-phenoxy benzyl-2,2,3, the 3-4-methyl cyclopropane carboxylic acid ester, structural formula is:
This compound is a kind of pyrethroid insecticides, and this agent to tag and stomach poison function, is not inhaled conduction in not having to the activity of insect, and is not undesirable with the effect of pest control of sucking mouth parts harm to some.
Imidacloprid (imidacloprid), chemical name: 1-(6-chloro-3-pyridylmethyl)-N-Nitroimidazoline-2-base amine, structural formula is:
This compound is a kind of efficient internal-suction type broad spectrum type insecticide, sucking mouth parts is had the better prevention effect, and toxicity is low, no cross resistance.
Three, summary of the invention:
The purpose of this invention is to provide a kind of insecticides, have and tag and interior suction double action, can replace the Pesticidal combination of high-toxic pesticide flolimat.
Technical scheme of the present invention is: insecticides, active ingredient are the mixture of fenpropathrin and Imidacloprid.
The weight ratio of described active ingredient fenpropathrin and Imidacloprid is 1: 0.05～10, preferred 1: 0.1～3.
Described insecticides active ingredient mixture weight percentage is 1～80%, preferred 5～40%.
The present invention can be prepared into missible oil, aqua, pulvis and other formulations of pesticide by general formulation method according to actual needs.
The adoptable surfactant of preparation 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.
The present invention can also 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: two kinds of existing dissimilar agricultural chemicals are carried out composite, reach mutually the purpose of covering the shortage, increase effect.Fenpropathrin mainly acts on the conduction central nervous system of insect, application point in insect bodies is an insect nicotinic acid acetylcholinesterase acceptor, what disturb is the insect motion nervous system, two kinds of insecticide action differences, with certain proportion obvious synergistic effect is arranged after using with, the more important thing is and significantly reduced poisoning, is the desirable insecticides that replaces the high-toxic pesticide flolimat.
Five, embodiment:
The present invention is described in further detail below in conjunction with embodiment.
Embodiment 1
Get 5 kilograms of the former medicines of Imidacloprid, add small amount of toluene, intensification 30-40 ℃ dissolving, add 15 kilograms of cosolvents again, stirring condition adds 10 kilograms of the former medicines of fenpropathrin down, adds 5 kilograms in auxiliary agent fatty acid polyoxy alkane alkene ester phosphate, emulsifier alkylol polyoxyethylene groups ether calcium sulphate again, stirred 2 hours down at 50 ℃, add toluene again and make it total amount and reach 65 kilograms, continue again to stir 2 hours, obtain homogeneous phase transparent missible oil.
Embodiment 2
Get 2 kilograms of the former medicines of Imidacloprid, add and have in the enamel reaction still of heater, add small amount of toluene, be warming up to 30-40 ℃ of dissolving, add 10 kilograms of cosolvents again, stirring condition adds 12 kilograms of the former medicines of fenpropathrin down, add 5 kilograms in auxiliary agent alkyl aralkyl phenol, emulsifier alkylphenol-polyethenoxy base ether again, stirred 2 hours down, add toluene again and make it total amount and reach 71 kilograms at 45 ℃, continue again to stir 1.5 hours, obtain homogeneous phase transparent missible oil.
Calculate CTC (co-toxicity coefficient) value with LC50 and proportioning that Polo calculates, draw table 1, table 2.The CTC value is an antagonism less than 100, and greater than 100 for synergistic effect, about 100 is summation action.With the citrus leaf-miner is target pest, uses the mixture determining lethality of the Imidacloprid of fenpropathrin and different proportion, and field control sees Table 3.Table 1 fenpropathrin and Imidacloprid are used co-toxicity coefficient (CTC) statistical form (LC with
50)
Show visible CTC value of the present invention thus and be far longer than 100, have obvious synergistic effect.
