Timing & weather
- Application should be made at normal pinching times
- To optimize the vigor of cuttings, do not make application for 2 weeks prior to the harvest of cuttings from the treated stock plants.
- On finished plants, do not make application for 6 to 8 weeks prior to bloom or planned sale.
- Apply only after the buds are mature or some injury may result.
- Apply in the fall just prior to frost.
- Short day lengths enhance response.
- Do not apply before September.
- Application before September may result in deformed inflorescences.
- Winter flowering of plumeria is attained when treatments are made in October.
- Defoliation is enhanced by short day lengths and water stress.
- Apply FLOREL BRAND GROWTH REGULATOR spray solutions within 4 hours after mixing.
Use restrictions 4
- To prevent unacceptable plant injury, do not treat sensitive varieties such as Sweetheart.
- Do not treat sensitive varieties such as Red American Beauty as bud injury may result.
- Do not use on Rome apples as defoliation will not be satisfactory.
- DO NOT save unused diluted spray solutions as they will not be as effective as fresh solutions.
