Design and Testing of Spraying Drones on Durian Farms

In modern times, the development of smart agriculture and digital countryside has become an important aspect of agricultural growth, as Thailand increasingly focuses on economics to improve farming practices. In Thailand, unmanned aerial vehicles (UAVs), also known as drones, are being utilized in durian farms with dense canopies of leaves. This technology enables more sustainable chemical treatments, by reducing the amount of chemicals sprayed, saving time, and protecting people's health. This study aimed to identify the best drone spraying solution for durian trees by analyzing sprayer droplet images. A smartphone app called Snap Card was used to evaluate the coverage and effectiveness of spray treatments on water-sensitive paper(WSP). The results reveal that the DJI T30 sprayer performs better than the DJI T20P due to the UAVs' droplet distribution and coverage. Additionally, the flight parameters, the environment's conditions, and various nozzle types are addressed for effective distribution in Durian trees. According to the findings of this study, unmanned aerial vehicles (UAVs) provide fascinating prospects for increasing modern technology efficiency in agriculture.
