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 chemical and biological property, cynapse acceptor to insect has the nerve block effect, various aphids, aleyrodid, leafhopper are shown remarkable activity, and have efficient, low toxicity, interior suction, no cross resistance simultaneously, crop had advantage such as poisoning, be widely used in paddy rice, fruit tree, vegetables and tea and prevent and treat multiple 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 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 takes place the heavy time, and is single with the difficult effectively control of Mobucin harm.
The inventor 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 of taking place on the target crop.

Biological Examples 1: Nitenpyram and cyhalothrin are used the toxicity test to cabbage aphid with
On the basis of preliminary experiment, behind former medicine of 95% 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 the beaker stand-by.The blade infusion process of recommending with reference to FAO is carried out Toxicity Determination then.Gathering the blade of band aphid on wild cabbage ground takes back indoor at the binocular stereo microscopically, remove winged viviparious female aphid and other insect and impurity with writing brush, the wingless aphid that keeps individual big or small basically identical, be dipped in each dilution together with leaf and take out behind the 10S, about 50 of every processing are blotted unnecessary soup with suction paper, put into the glass culture dish of the wet filter paper of pad, every reason weighs 3 times, handles in contrast with clear water, places in the greenhouse of (25 ± 1) ℃.Handle back 48h and check dead, the aphid number of living, calculate lethality,, calculate LC with DPS software with each lethality of handling of Abbott formula correction
50And virulence regression equation.Adopt Sun Pei cloud method to obtain the co-toxicity coefficient (CTC) of each mixed ratio with reference to NY/T1154.7-2006, and estimate the synergistic effect that the two is used with.The result is as shown in table 1:
Table 1: Nitenpyram and cyhalothrin are to the toxicity test result of cabbage aphid
Alkene: merit=Nitenpyram: cyhalothrin
Biological Examples 2: Nitenpyram and Biphenthrin are used with the tea lesser leafhopper toxicity test
On the basis of preliminary experiment, behind 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 the beaker stand-by.The drop method that adopts NY/T1154.1-2006 to recommend during mensuration, places 9cm culture dish CO to worm earlier
2Slight anesthesia, then with 1 μ L microsyringe 0.2 μ L soup point on polypide, be contrast with 0.2 μ L acetone treatment.Moisture releasing profit cotton balls is preserved moisture, and every ware is handled 20 of examination worms, moves in the climatic cabinate of (28+1) ℃, RH80% to raise.Handle back 48h, check dead borer population that each is handled, to be that polypide is immobile all be judged to death to dead standard.With each lethality of handling of Abbott formula correction, calculate LC with DPS software
50And virulence regression equation.Adopt Sun Pei cloud method to obtain the co-toxicity coefficient (CTC) of each mixed ratio with reference to NY/T1154.7-2006, and estimate the synergistic effect that the two is used with.The result is as shown in table 2:
Table 2: Biphenthrin and Nitenpyram are used with tea lesser leafhopper toxicity test result
Alkene: connection=Nitenpyram: Biphenthrin
Biological Examples 3: Nitenpyram and Mobucin are used the toxicity test to rice fulgorid with
On the basis of preliminary experiment, behind 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 the beaker stand-by.The drop method that adopts NY/T1154.1-2006 to recommend during mensuration, places worm the 9cm culture dish slightly to anaesthetize with CO2 earlier, then with 1 μ L microsyringe 0.2 μ L soup point on polypide, be contrast with 0.2 μ L acetone treatment.Moisture releasing profit cotton balls is preserved moisture, and every ware is handled 20 of examination worms, moves in the climatic cabinate of (28+1) ℃, RH80% to raise.Handle back 48h, check dead borer population that each is handled, to be that polypide is immobile all be judged to death to dead standard.With each lethality of handling of Abbott formula correction, calculate LC with DPS software
50And virulence regression equation.Adopt Sun Pei cloud method to obtain the co-toxicity coefficient (CTC) of each mixed ratio with reference to NY/T1154.7-2006, and estimate the synergistic effect that the two is used with.The result is as shown in table 3:
