Abstract
The invention discloses an insecticidal composition containing tefluthrin and neonicotinoids. The composition comprises an active ingredient A and an active ingredient B, wherein the active ingredient A is selected from the tefluthrin, the active ingredient B is selected from one of clothianidin, thiacloprid, nitenpyram and dinotefuran, and the weight ratio of the active ingredient A and the active ingredient B is (1:80)-(80:1). The composition has a synergy on various pests which are harmful to agricultural production, the usage amount of pesticides and the residue amount of pesticides on crops are reduced, the environment pollution is reduced, persons and animals are safe, the environmental compatibility is good, and the drug resistance is difficult to develop for pests.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of Pesticidal combination on crop pests that contains tefluthrin and anabasine.
Background technology
Tefluthrin (Tefluthrin) chemical name: 2,3,5,6-tetrafluoro-methyl-benzyl (suitable)-(1RS, RS)-3-(2-chloro-2,3,3-trifluoropropyl-1-thiazolinyl)-2,2-dimethyl cyclopropane carboxylic acid ester, molecular formula: C
17H
14ClF

2Tefluthrin is the pyrethroid that can be used as soil insecticide as first, and is efficient to coleoptera, Lepidoptera and dipteral insect, can granule, soil sprays or the mode of seed treatment is used.Its volatility is good, can in gas phase, fully divide a word with a hyphen at the end of a line with the control soil pests.Half life period be about one month big Tanaka, thereby it can keep longer residual effect to insect, and be unlikely in soil, to cause extended residual.
Thiophene worm amine, thiophene worm quinoline, Nitenpyram, MTI-446 all belong to novel nicotine compound, act on the nicotinic acid acetylcholinergic receptor of insect, and have stronger interior suction, tag and stomach poison function, be the specific drug of controlling sucking insects and chewing type insect.
Summary of the invention
Tefluthrin, thiophene worm amine, thiophene worm quinoline, Nitenpyram, the long-term use of MTI-446 list agent possibly bring degradation problem under resistance generation, the drug effect; The Pesticidal combination that the present invention proposes contains active components A and active component B, and an amount of surfactant and carrier.
A kind of Pesticidal combination that contains tefluthrin and anabasine; Contain active components A and active component B; Active components A and active component B weight ratio are 1: 80～80: 1; Described active components A is selected from tefluthrin, and active component B is selected from a kind of in thiophene worm amine, thiophene worm quinoline, Nitenpyram, the MTI-446, and active components A and the preferred weight ratio of active component B are 1: 60～40: 1; More preferably the weight ratio of tefluthrin and thiophene worm amine is 1: 30～15: 1; The weight ratio of tefluthrin and thiophene worm quinoline is 1: 30～15: 1; Tefluthrin and Nitenpyram weight ratio are 1: 20～20: 1, and tefluthrin and MTI-446 weight ratio are 1: 20～20: 1.
The described Pesticidal combination that contains tefluthrin and anabasine is used to prevent and treat the purposes of insect on fruit tree, vegetables, cereal crops, fiber crop, legume crop, ornamental plants, lawn, the forest.
Described insect comprises: rice fulgorid, Bemisia tabaci, aphid, longicorn, striped rice borer, paddy stem borer, rice leaf roller, thrips, fleahopper silk worm, cotton bollworm, pink bollworm, flea beetle, 12 star first, wireworms, chafer, latent food first, cutworm, corn borer, Oscinella frit.
The weight ratio of active components A, active component B is 1: 80～80: 1.Usually the weight percentage of active component is 0.5%～90% of a gross weight in the composition, and preferable is 5%～80%.According to different preparation types, the active component content scope is different.Usually, liquid preparation contains 1%～70% active substance by weight, preferably is 5%～50%; Solid pharmaceutical preparation contains 5%～80% active substance by weight, preferably is 10%～80%.
At least contain a kind of surfactant in the Pesticidal combination of the present invention, the dispersion of active component in water when being beneficial to use.Surface-active contents is 5%～30% of a total formulation weight amount, and surplus is solid or liquid diluent.
The surfactant that Pesticidal combination of the present invention is selected for use is known in those skilled in the art: can be selected from dispersant, wetting agent, binding agent or the antifoaming agent one or more.According to different dosage form, can also contain disintegrant known in those skilled in the art, antifreeze etc. in the preparation.
Pesticidal combination of the present invention can be by the user before use through dilution or directly use.Its preparation can be by common processing method preparation known in those skilled in the art; Be about to active substance and after liquid flux or solid carrier mix, add in surfactant such as dispersant, stabilizing agent, wetting agent, binding agent, the antifoaming agent etc. one or more again.
Pesticidal combination of the present invention; Can be processed into acceptable forms on any agricultural chemicals on demand, wherein more preferably formulation is wetting powder, water dispersible granules, suspending agent, suspension emulsion, aqueous emulsion, microemulsion, microcapsule suspending agent, microcapsule suspension-suspending agent.

The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.Pass through Toxicity Determination earlier, the co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC＜80 are antagonism, and 80≤CTC≤120 are summation action, and CTC＞120 are synergistic effect, on this basis, carry out field trial again.
Test method: respectively the mother liquor of each mixed agent is diluted to five series concentration during test, places beaker subsequent use respectively.Adopt and to soak the method that connects worm behind the leaf earlier, the blade of the same size that does not contact any medicament is soaked taking-up behind the 5s, dries naturally in the soup that configures, put into insect box; Connect then and supply the examination larva, under 25 ℃ of conditions, raise, every processing repeats for 3 times; Every to repeat used examination borer population be 50, establishes blank simultaneously, checks dead borer population in 72h; Calculate lethality and corrected mortality, try to achieve virulence regression equation and calculate LC
50Value.If the contrast lethality then is regarded as invalid test greater than 10%.Computing formula is following:
The insect corrected mortality is converted into probit value (y), and concentration of treatment (μ g/ml) converts logarithm value (x) to, draws virulence regression equation with method of least squares, and calculates the value of every kind of medicament thus, calculates co-toxicity coefficient CTC according to the abundant equation of Sun Yun.Computing formula is (with the tefluthrin is the standard medicament, and its toxicity index is 100) as follows:
TI * the P of theoretical toxicity index (TTI)=tefluthrin of M
TefluthrinTI * P of+effective active composition B
Effective active composition B
In the formula: M is the mixture of different proportionings
P
Effective active composition BBe effective active composition B shared ratio in composition
P
TefluthrinBe tefluthrin shared ratio in composition
B is selected from a kind of in thiophene worm amine, thiophene worm quinoline, Nitenpyram, the MTI-446.
