The Performance of Knapsack Air Carrier Sprayer: Pest Control of Citrus and Guava Trees

In this book some factors affecting on the sprayer performance to achieve its ability to pesticide orchard trees with high field efficiency was investigated under nine treatments with different solution flow rates (50.3, 78.4, 116.5 L/h) and different air velocities (17.5, 23, 27.5 m/s) to measure the deposition of solution and distribution of droplets . Also, a sprayer was used for spraying Guava and Citrus trees to pesticide Citrus leaf miners in Citrus and Red scale insect in Guava.
