Implication

Field experiment reveals that lower drone fungicide application rates provide effective Sigatoka control in banana crops, suggesting operational efficiency can be improved without losing efficacy.

Key Points

To evaluate the impact of different application rates and droplet sizes delivered by a remotely piloted aircraft on spray deposition quality and Sigatoka disease mitigation in 'Prata' banana crops.
Tested four application rates (8, 10, 12, and 14 L ha−1) and three droplet size classes (180, 240, and 300 μm) delivered by a remotely piloted aircraft in a field experiment on 'Prata' cultivar banana plants.
Measured quantitative spray coverage and droplet deposition, and evaluated biological disease control efficacy using the Stover Index.
Application parameters significantly affected droplet deposition and coverage across the crop canopy.
No significant monotonic association was observed between spray deposition indicators and biological disease mitigation.
Lower application rates of 8 L ha−1 achieved disease control levels comparable to higher application rates up to 14 L ha−1, indicating a biological control threshold can be met with lower quantitative deposition.
