DISEASES COMMENTS
B-Nine is typically used at 2,500 ppm to assist in minimizing internode stretch. The first application should be made approximately 2 weeks after the pinch, when new shoots are about 1.5 in. (4 cm) in length. Then spray once a week for about 3 weeks. Paclobutrazol drench at 1 to 2 ppm has also shown to be effective. Lavender Dreams is naturally compact. Paclobutrazol drench 0.5 ppm or B-Nine spray at 2,500 ppm can be applied if needed. Generally not needed. Sumagic(S) 5-10 ppm or a B-Nine 2,500-3,500 ppm and chlormequat chloride 1,000-1,500 tank mix(S) can be used to maintain habit as needed.

Is responsive to B‑Nine(S) 2,500‑3,500 ppm and chlormequat chloride(S) 1,000‑1,500 ppm tank mix or Sumagic(S) 5‑10 ppm.

Good branching coleus. No pinch. No PGR after transplant.
Downy mildew

Botrytis, Root rot
None
Benefits from a paclobutrazol(D) 2 ppm to control finished habit. Also can benefit from a Florel(S) 250 ppm tank mix with Configure(S) 75 ppm to increase branching.
