This manual provides low-cost technology suitable for small-scale Asian farms. The system of orchard management it recommends has proved highly successful on small farms in Vietnam, Taiwan and other Asian countries with warm, humid climates, where citrus orchards are under heavy pressure from pests and diseases. It follows an integrated approach that begins with layout and design, and continues with good soil and water management, as well as pest control. Constant monitoring allows growers to apply prophylactic sprays at an early stage of pest buildup. This helps to suppress pest populations in a way which makes minimum use of pesticides. Good pruning and canopy management are important for sprays to be effective. Systems of health management are aimed at minimizing pest and disease damage at an affordable cost.
