There is another post about a breakthrough treatment for citrus greening.
http://tropicalfruitforum.com/index.php?topic=40066.0The only previous treatmant I know of was placing the tree in a tent and increasing the
temperature. The Imidacloprid is for leaf minor and is not effective for greening.
Some people tried to plant Asain Guava near their citrus to attract the psyllid which
carries greening. Greening results in a tree producing about 1/3 of the usual crop
with 3-4x as much fertilizer. Most groves have been fertilizing year round and barely
being profitable with the reduced harvest. For door yard growers with a couple trees
you can expect your tree to produce 100-150 fruit per tree, not 350+ per tree like previously.
This is usually more then enough for a family. I have a Kishu tangerine and it has produced
300+ tangerines the past 3 years. More then enough for me to share.
