Pyracantha fire blight
Is "Arbor OTC" available in PA? Would Osytetracyline (the active ingredient in "Arbor OTC") as used in animals be a suitable substitute. If it is, how would the tablets be processed to produce the injectable?
Lebanon County Pennsylvania
Arbor OTC is registered for use in Pennsylvania. It would not be a good idea to use oxytetracycline meant for use in animals because products formulated for use in plants are made with different adjuvants to aid in uptake by plants that would not be present in animal products.
