Controlling citrus greening and the spread of psyllids is still a relevant problem.
The Tree Defender is not only the most effective and organic solution to this problem, it is the most affordable and economically valuable solution. By covering each tree, you are creating individual micro-environments that keep pests and diseases out. In the unlikely event, a tree does become infected in an individual protective cover, then the disease will not spread outside that cover and possibly harm the surrounding trees.
The larger protective covers are designed for mature trees. Each screen has a life expectancy of up to eight years and is also ideal for protecting various other small trees and plants such as tomatoes or peppers.
