Despite advancements in apple orchard systems, pesticide application volumes in Korea remain stagnant, ranging from 2,500 to 4,000 L/ha, often without specific guidelines. High pesticide volumes increase costs, pose health risks, and contribute to environmental degradation through drift. This study evaluated a tower-type sprayer‘s performance in high-density apple orchards, comparing low-volume (2,500 L/ha) and high-volume (4,000 L/ha) applications. Key metrics included drift, canopy coverage, mite density, and cost analysis. The results showed 1,500 RPM for 2,500 L/ha reduced drift compared to 2,000 RPM for 4,000 L/ha, though both exhibited drift up to 8 meters. Canopy coverage exceeded 80% across treatments, ensuring effective pesticide distribution. Mite density was controlled effectively with no significant differences, and fruit quality remained consistent. Economic analysis revealed total costs of 606,680 KRW for 2,500 L/ha and 1,111,760 KRW for 4,000 L/ha, indicating that the low-volume spraying reduced total costs by approximately 46% compared to the high-volume treatment, primarily due to decreased pesticide use, fuel, and labor. These findings suggest 2,500 L/ha is a cost-efficient and sustainable option, reducing environmental impact and resource use. Further research should address diverse pest species and adapt strategies for evolving orchard systems.
Abstract
Despite advancements in apple orchard systems, pesticide application volumes in Korea remain stagnant, ranging from 2,500 to 4,000 L/ha, often without specific guidelines. High pesticide volumes increase costs, pose health risks, and contribute to environmental degradation through drift. This study evaluated a tower-type sprayer‘s performance in high-density apple orchards, comparing low-volume (2,500 L/ha) and high-volume (4,000 L/ha) applications. Key metrics included drift, canopy coverage, mite density, and cost analysis. The results showed 1,500 RPM for 2,500 L/ha reduced drift compared to 2,000 RPM for 4,000 L/ha, though both exhibited drift up to 8 meters. Canopy coverage exceeded 80% across treatments, ensuring effective pesticide distribution.
