Summary of the invention
The object of the invention is to develop a kind of binary insecticides that contains compd A, insecticide effect is day by day improved to the demand of constantly updating with kind to meet agricultural and pest control aspect, urban health field.
Technical scheme of the present invention is as follows:
A kind of binary insecticides, active component one is selected from compd A, and active component two is selected from macrolide insecticides;
Described compd A has following structure:
Described macrolide insecticides comprises Avermectin (Abamectin), emamectin-benzoate (Emamectin benzoate is called for short first dimension salt), pleocidin (spinosad), ethyl pleocidin (spinetoram), emaricin (emamectin) or milbemectin (milbemectin) etc.
The preferred Avermectin of active component two, first dimension salt or pleocidin in binary insecticides of the present invention.
In binary insecticides of the present invention, the ratio of weight and number of two kinds of active components is 1: 99~99: 1, is preferably 1: 20~20: 1.
Indoor biological activity determination demonstrates binary insecticides of the present invention and has synergistic effect.For example, compd A and Avermectin have shown good synergistic effect to multiple target at 1: 20~20: 1 in scope; Compd A and first dimension salt in 5: 1~1: 2 scope, compd A and pleocidin all demonstrated synergistic effect at 5: 1~1: 1 in scope.
Composition of the present invention can be finished product preparation form to be provided.Therefore, the present invention also comprises a kind of insecticides of dosage form.Taking binary insecticides as active component, make as required missible oil, suspending agent, water-dispersible granules, aqueous emulsion, soluble liquid, wetting powder, oil-suspending agent etc.In composition, the cumulative amount of active component is between 0.5%~95%, and preferably cumulative amount is between 1%-85%.The amount of application when content of active component depends on independent use in composition of the present invention, also depends on mixed ratio and synergistic effect degree.The optimum range of active component content is different according to the preparation type of composition.

Indoor biological activity determination
The synergism determination of the composition that embodiment 15 contains compd A to diamond-back moth
For trying object: diamond-back moth (Plutella xylostella), 2 instar larvaes, the sensitive strain of indoor feeding.
Test condition: temperature: 24~26 DEG C, humidity: RH 60%, illumination: L: D=14: 10
Test method: adopt infusion process to process, the cabbage leaves of greenhouse culture is fetched, make diameter 2cm leaf dish, leaf dish is flooded to 5s in liquid, after taking-up, dry in the shade, put into the 9cm culture dish that is lined with filter paper, select in the examination worm access culture dish of neat and consistent, every processing repeats 4 times.Examination worm after treatment is placed in observation ward, routine observation examination worm response situation, 48h " Invest, Then Investigate " is dead, the borer population of living, and calculates lethality.
Evaluating and adopting Bliss method, the method is one of classical way of evaluating mixture effect.Bliss thinks according to the independent joint action concept of its proposition, and theoretical lethality P when Mixture Use of Insecticides can calculate with following formula:
P=P
m+P
n(1-P
m)
P
mit is the lethality (%) of the first active component target in the time that concentration is m; P
nit is the lethality (%) of the second active component working concentration target while being n.
If the actual of two kinds of active components target after mixing with finite concentration is greater than theoretical lethality P, judges that the mixing use under setting concentration of two kinds of active components has synergistic effect, otherwise be antagonism.
The results are shown in Table 1.
