Experiment code 19.3.3.93
Experiment Title Assessment of Unmanned Aerial Vehicle (UAV) based spraying to manage sheath blight disease of rice
Research Type Departmental Research
Experiment Background Pests in crops significantly affect agricultural production and due to that world had to face about 30% of crop loss annually. Therefore, it is prime objective to adopt an efficient crop protection technology which can effectively control pests for agricultural productivity and sustainability. Aerial spraying by Unmanned Aerial Vehicle (UAV) is an emerging practice in many developed countries as well as developing country like India. Indian farmers use conventional sprayers, which leads to excessive use of chemicals, less spray uniformity, low deposition, higher cost of spray operation and environment pollution. The use of UAV for spraying pesticides can improve spray quality, timeliness, effectiveness and reduce labour cost also. The unmanned aerial vehicle spraying system saved up to 50% pesticides and 90% water compared to high clearance crop sprayer.
