Randomized trial evaluates UAV flying height and speed effects on spider mite and thrip control in cotton, suggesting optimized parameters for better pesticide application.
Key Points
The study aims to evaluate the effects of UAV operational parameters on spray efficacy against pests in cotton.
Evaluated hexacopter UAV at three flying heights (2, 2.5, and 3 m) and three speeds (3, 3.5, and 4 m/s).
Used a factorial randomized block design for assessment.
Measured droplet density, size, spray coverage, and pest control effectiveness.
Most effective conditions: 2 m height and 3 m/s speed, with max droplet density of 48.50 droplets/cm².
Achieved high control efficacy: 88.78% for spider mites and 90.21% for thrips.
Highest field efficiency of 56.02% and cotton yield of 2546.56 kg/ha under optimized conditions.
