Can I treat plants with open flowers, buds or poinsettia bracts in color?
Phyton-27® is gentle on most plant material. It is safe to use on most open flowers and buds at lower rates. The exceptions are Gloxinia flowers and certain sensitive varieties of orchids. However, because it is impossible for us to test all varieties and colors under varying growing conditions, we recommend that you trial it on a small number of plants with flowers or buds at the intended dosage rate before treating the entire crop. Phyton-27® is safe to use on poinsettia bracts, even in full color, one of the few products that can be used at this critical stage in the growth cycle and with no residue.
