Abstract
While the citrus nurseries work very hard and put considerable effort to reduce pest and disease problems in nurseries, there continues to be problems with certain diseases, because the nursery environment for growing citrus trees is also ideal for many pests and diseases. Basic principles of good nursery sanitation practices together with screening and removing suspected or infected plants should be implemented in all nurseries to minimize the risk of pest and disease introduction and spread inside the nursery and in groves. The main goal of a nursery should be providing the highest quality trees to growers, with no exception. And, growers should pay extra attention to assure that all trees received are of acceptable quality before planting in their groves.
