Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of Pesticidal combination that contains ether chrysanthemum ester and thiophene worm amine.
Background technology
Ether chrysanthemum ester (ethofenprox), molecular formula: C
25H
28O
3, chemical name: 2-(4-ethoxyl phenenyl)-2-methyl-propyl-3-benzyloxy phenoxy base ether, ether chrysanthemum ester is the ethers pyrethroid insectide of no ester structure in a kind of molecule; Belong to never poison; Have tag, stomach poison function, inhale conduction in not having, ineffective to various pests such as Lepidoptera, Homoptera, Semiptera, coleoptera, dipteras; Have that insecticidal spectrum is wide, insecticidal activity is high, knock down that speed is fast, the lasting period is long, less to natural enemy lethality such as paddy field spiders, to advantages such as crop safeties.
Thiophene worm amine (clothianidin), molecular formula: C

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 of ether chrysanthemum ester thiophene worm amine 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 examination 3 instar larvaes, under 25 ℃ of conditions, raise, every processing repeats for 3 times; Every to repeat used examination borer population be 20, 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.Calculate co-toxicity coefficient CTC according to the abundant equation of Sun Yun.Computing formula is (with ether chrysanthemum ester is the standard medicament, and its toxicity index is 100) as follows:
TI * the P of the theoretical toxicity index (TTI) of M=ether chrysanthemum ester
Ether chrysanthemum esterThe TI of+thiophene worm amine * P thiophene worm amine
In the formula: M is the mixture of different proportionings
P
Thiophene worm amineBe thiophene worm amine shared ratio in composition
P
Ether chrysanthemum esterBe ether chrysanthemum ester shared ratio in composition
A is selected from ether chrysanthemum ester;
B is selected from thiophene worm amine.
Application implementation example two:
Supply the examination insect: the wild cabbage diamond-back moth.
Test medicine provides by Shaanxi agricultural chemicals Co., Ltd of U.S. nation.
