Abstract
The invention discloses a synergistic pesticide composition for preventing and treating fruit tree leaf cast. The synergistic pesticide composition comprises paclobutrazol and another active component at the mass ratio of (80 to 1) to (1 to 50), wherein another active component is any one or two of polyoxin and diniconazole. The synergistic pesticide composition for preventing and treating the fruit tree leaf cast, disclosed by the invention, has a certain synergistic effect on prevention and treatment of crop diseases; the resistance development is delayed; and the service life of the synergistic pesticide composition is prolonged.
Description
Technical field
The present invention relates to a kind of composition pesticide, be specifically related to a kind of synergetic pesticide composition preventing and treating defoliation of fruit trees disease.
Background technology
Apple tree early defoliation disease is that China's apple producing region generally occurs and the most serious a kind of disease, and when this disease is very popular, cause large stretch of fruit tree middle and lower part leaf abscission, on branch, apple is outside exposed, is called visually " sugarcoated haws ".Conventional protective fungicide can only play prevention effect, and interior absorbability bactericide Long-Time Service easily develops immunity to drugs, and therefore, the efficient interior absorbability composition pesticide that in production, urgent need exploitation makes new advances as an alternative.
Summary of the invention
First object of the present invention is to provide a kind of synergetic pesticide composition preventing and treating defoliation of fruit trees disease, comprises paclobutrazol and another active component that quality proportioning is 80:1 ~ 1:50.
The quality proportioning of described paclobutrazol and another active component is 20:1 ~ 1:20.
Another described active component is any one or two kinds in polyoxin, olefin conversion.
In described composition pesticide, the gross mass percentage composition of fenazaquin and flonicamid is 20% ~ 80%, all the other auxiliary elements allowed for pesticidal preparations.
Described composition pesticide is mixed with microemulsion, aqueous emulsion or wetting powder.
Second object of the present invention is to provide the application of the synergetic pesticide composition of this control defoliation of fruit trees disease in control apple tree defoliation.
In the present invention, paclobutrazol and polyoxin or the composite rear control to apple tree defoliation of olefin conversion have certain synergistic effect, extend medicament service life.
embodiment:
Below in conjunction with concrete case study on implementation, the present invention is described in further detail:
(1) formulation Example
Formulation Example 1:
Paclobutrazol 80 parts
Polyoxin 1 part
Xanthans 0.2 part
Stabilizing agent 0.8 part
Formulation Example 2:
Paclobutrazol 20 parts
Polyoxin 1 part
Xanthans 2 parts
Stabilizing agent 5 parts
Formulation Example 3:
Paclobutrazol 1 part
Polyoxin 10 parts
Olefin conversion 10 parts
Xanthans 10 parts
Stabilizing agent 25 parts
Formulation Example 4:
Paclobutrazol 1 part
Polyoxin 20 parts
Olefin conversion 30 parts
Xanthans 20 parts
Stabilizing agent 5 parts
(2) Application Example
The test of pesticide effectiveness of compound pesticide composition of the present invention
The evaluation of pesticide effectiveness of apple tree defoliation prevented and treated by table 1
| Dosages distribution | Extension rate | Access times | Sick leaf rate (%) | Control rate (%) |
| Paclobutrazol 80 parts | 10 | 3 | 15.2 | 79.0 |
| Polyoxin 80 parts | 10 | 3 | 14.0 | 65.2 |
| Olefin conversion 80 parts | 10 | 3 | 9.2 | 60.4 |
| Proportioning in embodiment 1 | 10 | 3 | 15.8 | 80.9 |
| Proportioning in embodiment 2 | 10 | 3 | 11.0 | 82.7 |
| Proportioning in embodiment 3 | 10 | 3 | 13.5 | 90.3 |
| Proportioning in embodiment 4 | 10 | 3 | 10.8 | 88.4 |
After measurement result indicates that paclobutrazol and polyoxin or olefin conversion are composite, concerning apple tree defoliation between composite scope 80:1 ~ 1:20, show control rate (more than 80%) higher when being obviously comparatively used alone.
