Abstract:

This research focuses on exploring the efficacy of UAVs on crop protection for rice. Experiment factors include different UAVs, spray volume and flight parameters. Pre-emergence herbicides and pesticides are tested. Results show that when the spray volume is 10650 and 15000 mL/hm2, no significant difference is observed for control efficacy on weeds between UAV application and manual application. When the spray volume is 10650 and 15000 mL/hm2 in pests and disease control efficacy test, the efficacy is not affected even when the pesticide dosage is decreased by 30% at the spray volume of 15000 mL/hm2. Therefore, using UAV to apply pre-emergence herbicides and pesticides is feasible. Selecting appropriate pesticides and scientific spraying parameters can reduce pesticide usage. The application of UAVs in rice crop protection has a broad prospect.
