Abstract
The invention discloses an insecticide composition. The insecticide composition contains two effective constituents A and B, wherein, A is tefluthrin and B is either fipronil or butene-fipronil. The mass ratio of the A to the B is 80:1-1:40. The combination of the A to the B produces obvious synergism, which can reduce use amount of the effective constituents and the number of pesticide application. The insecticide composition can be applied to control various soil insects in agriculture, especially such soil insects as wireworms, scarab, black cutworms and the like.
Description
Technical field
The present invention relates to a kind of Pesticidal combination, the application of specifically a kind of Pesticidal combination that contains tefluthrin, and said composition on agricultural insect pests control.
Background technology
Tefluthrin (Tefluthrin) belongs to pyrethroid insecticides, is soil insecticide, can prevent and treat well coleoptera and Lepidoptera and some Diptera pest of perching in soil.But control soil arthropod in wide spectrum ground comprises pumpkin 12 star first, wireworms, flea beetle, chafer, Atomaria linearis, cutworm, corn borer, Sweden's wheat stem chloropid fly etc.
Ethiprole (Fipronil) is that a kind of Phenylpyrazole insecticides, insecticidal spectrum are wide, and insect take stomach poison function as main, is had concurrently and tags and certain systemic action.This medicament can impose on soil, but also foliar spray.Impose on soil effectively chrysomelid, the wireworm of control of maize root and cutworm.
Butene-fipronil is the Phenylpyrazole insecticides.Butene-fipronil has control efficiency preferably to various pests such as Homopteras, in particular for the control of the insects such as paddy rice, vegetables, to the fish low toxicity, has wide application space due to this compound.
Ethiprole and butene-fipronil are higher to underground insect activity, but single dose uses and easily to produce resistance, and ethiprole and butene-fipronil be used for separately the control of soil insect, and be higher to weak effect and the cost accounting of cutworm class.
Summary of the invention
The object of the present invention is to provide a kind of composition pesticide, said composition the notable synergistic effect arranged, can reduce ethiprole and butene-fipronil cost in the use.Another purpose of invention is to provide the application of said composition on agricultural.
The present invention realizes in the following manner:
The present invention contains A and two kinds of active ingredients of B, and wherein A is tefluthrin, and B is a kind of in ethiprole or butene-fipronil, and the mass ratio of A and B is 80: 1-1: 40.
As a modification of the present invention, the mass ratio of tefluthrin and another active parasite killing composition is 20: 1-1: 20.
The present composition is processed in actual applications and is fit to the upper any formulation used of agricultural, and preferred dosage form is granule, suspending agent, oil-suspending agent, missible oil, water dispersible granules and wetting powder.
The present composition can be used for preventing and treating the various agricultural insect, is particularly useful for the soil insects such as wireworm, grub and cutworm class.
The present composition is compared with prior art, produces following beneficial effect: 1. two kinds of active ingredients in composition are composite has a synergistic effect, obviously improves the control efficiency to target pest; 2. the mechanism of action of two kinds of active ingredients is different, and the notable synergistic effect is arranged, and can be used for the improvement of resistant insect; 3. the Pesticidal combination that has synergistic effect can reduce the field dosage, and single dose can reduce drug cost relatively, and effectively environmental contamination reduction and residue of pesticide, reduce the harm to beneficial organism.

Embodiment 11: tefluthrin and Firponil compounded joint toxicity measuring to Agriotes subrittatus Motschulsky 3 instar larvaes
Test medicine: the 95% former medicine of tefluthrin (Jiangsu Agricultural Hormone Engineering Technology Research Centre Co., Ltd.), the 90% former medicine of ethiprole (Anhui China star chemical industry Co., Ltd).
Test method: adopt the mixed medicine method of soil.Each reagent agent is mixed with certain mass concentration mother liquor take acetone as solvent, and with the aqueous solution that contains 0.1% POLYSORBATE 80, above each mother liquor is mixed with respectively certain mass concentration for examination.Sandy loam is crossed 850 μ m sieves, disinfects 4h with the far infrared flash dryer under 120 degrees centigrade.Take as above dry soil samples 1.0Kg/ part, get a certain amount of liquid and add in dry ground, then after adding suitable quantity of water, make its soil moisture content approximately 18%.This pesticide-clay mixture is stirred in " V " type mixer mixed it in 2 minutes, the glass that accesses 1 Agriotes subrittatus Motschulsky of packing into is supported scolite (diameter 1.8cm, high 8cm) in, put into a small amount of just germinated wheat seed as food, plug is escaped with control examination worm beyond the Great Wall.With the distilled water that contains 0.1% POLYSORBATE 80 and 0.1% acetone as blank.Every processing examination worm is no less than 60, repeats 3 times.Examination worm after processing is placed in temperature, and to be about 24 degrees centigrade, humidity be that raise in the greenhouse of 60% left and right.
Check afterwards examination worm death condition (death standard: what polypide obviously shrank or touched can not normally creep) in 5 days, and calculate lethality.
It is co-toxicity coefficient (CTC) method that mode of application adopts the abundant method of calculating the mixture co-toxicity by toxicity index that waits that nineteen sixty proposes of Sun Yun.The computing formula of co-toxicity coefficient is as follows:
Actual measurement toxicity index (ATI)=(standard medicament LC
50/ reagent agent LC
50) * 100
The percentage composition of B in the percentage composition of A+B medicament ATI * mixture in theoretical toxicity index (TTI)=A medicament ATI * mixture
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/theoretical toxicity index (TTI) of mixture] * 100
When CTC≤80, the composition performance is for antagonism, and when 80＜CTC＜120, the composition performance is for summation action, and when CTC 〉=120, the composition performance is synergistic effect.
