Features:- Concentrated oil is mixed with water then sprayed on your tree to control a variety of insects.
- Controls mites, scale insects, galls, mealy bugs, aphids and other insects.
- Horticultural Oil Insect Spray kills insects by blocking their pores and smothering them.
- 1 Pint (473.16mL) concentrate makes about 6-13 gallons of spray, enough to treat 2-3 large trees.
Not sure:
I spray it (diluted) on cucumber plants to treat spider mites and on orange trees to treat scales. It worked OK on the scales, but I am not sure it did anything to the spider mites. Those little red critters are every where now, on cucumbers and string beans. I am still trying to find an "organic way" to treat them.
Better for smaller trees:
We bought this spray to treat gall mites on our Silver Maple trees. It worked to reduce the number of mites but didn't completely cure it. In order for it to work you have to pretty much saturate the entire trunk and branches. From what I've read, the oil suffocates the mites so they can't come out and settle on the leaves where they reproduce. You have to spray the entire tree in the Fall after the leaves fall off and in the Spring before the tree buds. If you have a larger tree, this might not be possible.
