Abstract
The invention discloses an insecticidal composition of thiacloprid and emamectin benzoate. The combination of the thiacloprid and the emamectin benzoate can ensure that the probability of the drug resistance generated in the pests is greatly reduced and the cost is reduced while the drug effect is improved. The weight ratio of the thiacloprid to the emamectin benzoate is 20:1-1:20. Through indoor tests, all weight ratios of the emamectin benzoate to the thiacloprid, such as 1:5, 1:10, 1:20, 5:1, 10:1, 20:1, all show the summation action, and the effect of the thiacloprid and the emamectin benzoate after compounded is superior to the thiacloprid preparation and the emamectin benzoate preparation. Through field tests, the ratio of the thiacloprid to the emamectin benzoate is 1:1, the concentration of the thiacloprid and the emamectin benzoate is respectively 2 percent, 10 percent, 20 percent and 40 percent, the insecticidal effect after the thiacloprid and the emamectin benzoate are compounded is superior to the thiacloprid preparation and the emamectin benzoate preparation.
Description
Technical field the present invention relates to a kind of agricultural insecticide, is the Pesticidal combination of a kind of thiophene worm quinoline and emamectin-benzoate specifically.
Background technology thiophene worm quinoline (thiacloprid) belongs to anabasine insecticide, and interior absorption is stronger, have tag, stomach poison function, insecticidal spectrum is wide.
(Emamectin benzoate (B1a/B1b) is an Avermectin B1 structure modified outcome to emamectin-benzoate, and the insecticidal activity that compares the lepidoptera pest larva with the parent Avermectin is significantly improved, and toxicity but reduces greatly.Prove through the test of pesticide effectiveness repeatedly, first dimension salt pair resistant bollworm and diamond-back moth special efficacy, active in the parent Avermectin, be better than conventional dose simultaneously.First dimension salt has used for many years, and pesticide resistance is in various degree also arranged, and two kinds of compositions are mixed and can increase the drug effect of product, make insect be difficult for developing immunity to drugs.
300 yuan/kg of the former medicine of thiophene worm quinoline in addition, 900 yuan/kg of the first dimension former medicine of salt, two kinds of compositions synthesize under the prerequisite that guarantees drug effect and can reduce cost.
Summary of the invention the object of the present invention is to provide the Pesticidal combination of a kind of thiophene worm quinoline and emamectin-benzoate, and the probability that two kinds of drug regimens can make insect develop immunity to drugs greatly reduces, and reduces cost when improving drug effect.
Technical scheme of the present invention is as follows:
The active ingredient of this Pesticidal combination is thiophene worm quinoline and emamectin-benzoate, and the weight ratio of thiophene worm quinoline and emamectin-benzoate is: 20: 1~1: 20.
The weight percentage that above-mentioned thiophene worm quinoline and emamectin-benzoate account for total preparation is 2%~40%, and surplus is an auxiliary agent.
The concrete formulation of above-mentioned insecticide is aqua, missible oil, suspending agent, wetting powder, granule, microemulsion.
The invention has the advantages that: 1, through laboratory test, methylamino dimension rhzomorph benzoate and thiophene worm quinoline be with 1: 5,1: 10,1: 20,5: 1,10: 1, each proportioning all showed summation action in 20: 1, and the back insecticidal effect that is mixed all is better than list agent of thiophene worm quinoline and the agent of methylamino dimension rhzomorph benzoate list.Through field trial, thiophene worm quinoline and methylamino dimension rhzomorph benzoate is with 1: 1 proportioning, concentration respectively 2%, 10%, 20%, 40%, and the back insecticidal effect that is mixed all is better than list agent of thiophene worm quinoline and the agent of methylamino dimension rhzomorph benzoate list.2, both are mixed and can reduce the pesticide resistance of crop pests.3, because of thiophene worm quinoline cost is low, the effective but cost height of methylamino dimension rhzomorph benzoate pesticide, both applied in any combination had both improved drug effect, reduced cost again.
