Hi Jim: My trees covered by green stuff like moss it later on kill the tree, so where can I get: Kocide 101 77W (1 level tablespoon per gallon) and Kocide DF (?level tablespoon per gallon).

Answer
These are lichens. And can be controlled with the Kocide product however Kocide DF has been discontinued. I would use Korcide 2000 or check with your local garden type store or nursery for one of the Krocide products. Here is more information on lichens and their control. I would also fertilize the trees with 10-10-10 fertilizer at the rate of 1 lb per inch of trunk diameter scattered around the tree and watered in good--apply just before a rain storm and you will not need to water.
