Citrus greening is one of the most devastating diseases of citrus in Asia. Citrus greening was first identified in South Africa fifty years ago. It is now found all over the tropical and subtropical countries of Asia. In the Philippines, citrus greening is the main reason why citrus production fell by 60% between 1961 and 1970. In Vietnam, up to 90% of the citrus trees in some areas are believed to be infected with citrus greening.

There are three main objectives. The first is to increase the total effective leaf area, and promote photosynthesis by exposing the leaves to light and air. If branches are well spaced and properly oriented, they have plenty of space and light. This improves the efficiency of their water use, and also their conversion of available plant nutrients. In turn, this increases the yield and quality of the fruit.
