Working for Alltech Crop Science, we began an experiment a little over two years ago to study citrus greening. We chose to use The Tree Defender to protect the trees we were studying in order to continue our experiment. When the hurricane hit last year, we did not lose a single tree being protected by The Tree Defender, which not only saved us money but saved the entire experiment and kept us from having to start over. Had we used a screen house, our trees and experiment would have been destroyed. I use The Tree Defender for my personal grove as well and am pleased with their ability to protect my trees.
