Table 1 is the contrast of the inventive method and top spraying method application result, reflects spraying method of the present invention
The effect that table 1 difference is prevented and treated method compares
| Project | Control efficiency | The control amount of liquid medicine |
| The top spraying method | 55.0％ | 50kg/667m 2 |
| Spraying method of the present invention | 81.2％ | 40kg/667m 2 |
Annotate: application medicaments is 80%DDV, and the Hubei sand swell reaches production, and controlling object is a rice fulgorid.Effect.Using traditional rice plant top spray medicine, to prevent and treat the control efficiency of method (control efficiency relatively---the worm amount of being killed accounts for the percentage of the worm amount before the spray medicine) be 55.0%, and the control efficiency of using spraying method of the present invention is 81.2%; The dosage of top spraying method is 50kg/667m
