To explore the effectiveness of plant protection drones in the prevention and control of rice diseases,self-propelled sprayers and plant protection drones were used as the main plant protection machinery,and rice bacterial leaf streak and neck blast were selected as test subjects.Three treatments of plant protection drone treatment,self-propelled sprayer treatment and control treatment were set.The results showed that both types of plant protection machinery could effectively control the two rice diseases.In terms of preventing and controlling rice bacterial leaf streak,both machineries had good control effects compared with the control,with disease index values of 0.43 and 0.25,and control efficiencies of 91.15%and 94.86%,respectively.In terms of preventing and controlling neck blast,the self-propelled sprayer had the best control effect,with a disease index of 0.14 and a control efficiency of 96.38%.Compared to the self-propelled sprayer treatment,the use of plant protection drones can further reduce the time and cost of preventing and controlling rice pests,reduce water usage,save resources,and reduce the risk of poisoning,which is more suitable for the control of crop diseases and pests under large-scale planting.
