Description
Technical field
The present invention relates to a kind of synergetic pesticide composition, particularly relate to a kind of synergetic pesticide composition that comprises Nitenpyram and be selected from arbitrary active insecticidal components of cyhalothrin, Biphenthrin and Mobucin.
Background technology
Nitenpyram (nitenpyram) belongs to the nicotimine insecticides, have unique chemistry and biological property, cynapse acceptor to insect has the nerve block effect, various aphids, aleyrodid, leafhopper are shown remarkable activity, and have simultaneously efficient, low toxicity, interior suction, without cross resistance, to crop without advantages such as poisoning, be widely used in paddy rice, fruit tree, vegetables and tea control sucking insect.
Cyhalothrin (lambda-cyhalothrin) is to copy natural pyrethrin to carry out structure of modification and the insecticides that obtains, to insect than high 1 ~ 2 order of magnitude of other common insecticides, and characteristics that quick-acting is good, has repellent, the power of knocking down is fast.This insecticides all has good control efficiency to most of insects of the aspects such as agricultural, gardening, warehouse herding, health.
Biphenthrin (bifenthrin) belongs to the pyrethroid Insecticidal and acaricidal agent, have tag, stomach poison function.Its insecticidal spectrum is wide, and effect is difficult for moving in soil rapidly, and environmentally safe, the lasting period is longer.
Mobucin (isoprocarb) belongs to carbamate insecticide.Mobucin has good preventive effect to rice fulgorid, leafhopper etc., and quick-acting is strong, and adult is had special efficacy, but rice fulgorid, occurs the heavy time, and alone Mobucin is difficult for effectively controlling harm.
The present invention studies have shown that by a series of, Nitenpyram is mixed with the arbitrary active insecticidal components that is selected from cyhalothrin, Biphenthrin and Mobucin target pest is had extremely strong synergistic effect, has the more outstanding double effect of controlling to mixing the insect and the evil mite that occur on the target crop.
Summary of the invention

Embodiment:
The invention will be further described below in conjunction with embodiment.But the present invention only limits to absolutely not these examples.In all formulas, percentage all is weight percentage, and proportioning is weight ratio.It is known that the processing technology of the various preparations of the present composition and equipment are the public.
Formulation examples 1:
Take 25% Mobucin, 10% Nitenpyram, 5% lignosulfonates, 4%NO, 10% talcum powder, diatomite and complement to 100%.The frequent regulation of above-mentioned raw materials is got the steps such as the pulverizing, mixing of granule and is produced 35% Mobucin Nitenpyram wetting powder.
FORMULATION EXAMPLE 2:
Taking 10% Biphenthrin, 50% Nitenpyram, 8% dispersant, 4% wetting agent, 8% ammonium sulfate, 2% white carbon, diatomite mends to 100%.Above-mentioned raw materials is produced 60% Biphenthrin Nitenpyram water dispersible granules through ultramicro grinding, mixing, extruder grain step.
FORMULATION EXAMPLE 3:
Take 5% Biphenthrin, 10% Nitenpyram, 8% emulsifier special, toluene or dimethylbenzene and complement to 100%.Stirring and dissolving obtains 15% Biphenthrin Nitenpyram missible oil to mixing.
Biological Examples 1: Nitenpyram toxicity test to cabbage aphid mixed with cyhalothrin
On the basis of preliminary experiment, after the 95% former medicine of Nitenpyram and the former medicinal proper amount of acetone preliminarily solubilised of 91% cyhalothrin, and be mixed into the mother liquor of different proportionings in set ratio.Each mother liquor is mixed with 5 serial test solutions with distilled water, and concentration range can cause that supplying to try insect mortality reaches 10% ~ 90%, puts in beaker stand-by.The blade infusion process of then recommending with reference to FAO is carried out Toxicity Determination.Take back indoor at the binocular stereo microscopically with the blade of aphid in wild cabbage ground collection, remove winged viviparious female aphid and other insect and impurity with writing brush, keep the basically identical wingless aphid of Individual Size, be dipped in each dilution together with leaf and take out after 10S, unnecessary liquid is blotted with suction paper in every processing 50 left and right, put into the glass culture dish of the wet filter paper of pad, every processing repeats 3 times, processes in contrast with clear water, is placed in the greenhouse of (25 ± 1) ℃.After processing, 48h checks dead, the aphid number of living, and calculates lethality, with each lethality of processing of Abbott formula correction, calculates LC with DPS software
50And virulence regression equation.Adopt Sun Peiyun to obtain the co-toxicity coefficient (CTC) of each mixed ratio with reference to NY/T 1154.7-2006, and estimate both mixed synergistic effect.Result is as shown in table 1:
Table 1: Nitenpyram and the cyhalothrin toxicity test to cabbage aphid
Alkene: merit=Nitenpyram: cyhalothrin
Biological Examples 2: Nitenpyram and Biphenthrin are to the tea lesser leafhopper toxicity test
On the basis of preliminary experiment, after former medicinal proper amount of acetone preliminarily solubilised, and be mixed into the mother liquor of different proportionings in set ratio.Each mother liquor is mixed with 5 serial test solutions with distilled water, and concentration range can cause that supplying to try insect mortality reaches 10% ~ 90%, puts in beaker stand-by.The drop method that adopts NY/T 1154.1-2006 to recommend during mensuration, first is placed in 9cm culture dish CO to worm
2Slight anesthesia, then with 1 μ L microsyringe 0.2 μ L liquid medicine point on polypide, take 0.2 μ L acetone treatment as contrast.Put wetting cotton balls moisturizing, every ware is processed 20 of examination worms, moves in the climatic cabinate of (28 ± 1) ℃, RH80% to raise.48h after processing checks dead borer population that each is processed, and to be that polypide is immobile all be judged to death to dead standard.With each lethality of processing of Abbott formula correction, calculate LC50 and virulence regression equation with DPS software.Adopt Sun Pei cloud method to obtain the co-toxicity coefficient (CTC) of each mixed ratio with reference to NY/T 1154.7-2006, and estimate both mixed synergistic effect.Result is as shown in table 2:
