Abstract
The invention discloses a synergistic pesticide composition for preventing and controlling leaf defoliation of apple trees. The composition comprises paclobutrazol and tebuconazole in a mass ratio of 100:1-1:100. The composition has a certain synergistic effect on prevention and control of leaf defoliation of apple trees, and can be used for retarding resistance development and prolonging the service life of pesticides.
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 apple tree defoliation.
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 apple tree defoliation,
Comprise paclobutrazol and Tebuconazole that quality proportioning is 100:1 ~ 1:100.
The quality proportioning of described paclobutrazol and Tebuconazole is 50:1 ~ 1:20.
In described composition pesticide, the gross mass percentage composition of paclobutrazol and Tebuconazole is 20% ~ 80%, all the other auxiliary elements allowed for pesticidal preparations.
Described composition pesticide is mixed with microemulsion or aqueous emulsion.
Second object of the present invention is to provide the application of the synergetic pesticide composition of this control apple tree defoliation in control apple tree defoliation.
In the present invention, paclobutrazol and the composite rear control to diseases and pests of agronomic crop of Tebuconazole have certain synergistic effect; Delaying drug resistance develops, and extends medicament service life; Reduce costs.
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 100 parts
Tebuconazole 1 part
Xanthans 2 parts
Stabilizing agent 0.8 part
Formulation Example 2:
Paclobutrazol 50 parts
Tebuconazole 1 part
Xanthans 3 parts
Stabilizing agent 0.8 part
Formulation Example 3:
Paclobutrazol 1 part
Tebuconazole 20 parts
Xanthans 2 parts
Stabilizing agent 1 part
Formulation Example 4:
Paclobutrazol 1 part
Tebuconazole 100 parts
Xanthans 3 parts
Stabilizing agent 2 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 100 parts | 8 | 2 | 17.8 | 69.0 |
| Tebuconazole 100 parts | 8 | 2 | 18.8 | 68.2 |
| Proportioning in embodiment 1 | 8 | 2 | 10.5 | 78.9 |
| Proportioning in embodiment 2 | 8 | 2 | 15.2 | 81.1 |
| Proportioning in embodiment 3 | 8 | 2 | 11.4 | 88.4 |
| Proportioning in embodiment 4 | 8 | 2 | 12.1 | 90.8 |
Measurement result indicate paclobutrazol and Tebuconazole composite after, concerning apple tree defoliation between composite scope 100:1 ~ 1:100, show control rate (more than 80%) higher when being obviously comparatively used alone, control efficiency is more remarkable.
