FINISH PGRs
TECH TIPS
Usually not required. B-Nine ® WSG at 5,000 ppm before buds are wider than 1 cm (pea size). Later plant growth regulator (PGR) sprays may reduce flower size or cause flowering in the foliage.
Stretched plugs can be buried (up to the cotyledons) if necessary. Maintain media pH above 6.2 to avoid iron/ manganese toxicity. Short days will shorten time to flower.
FINISH PGRs
TECH TIPS
If necessary under low light or high temperature/humidity conditions, spray with B-Nine ® WSG at 5,000 ppm before buds are wider than 1 cm (pea size).
Stretched plugs can be buried (up to the cotyledons) if necessary. Maintain media pH above 6.2 to avoid iron/ manganese toxicity. Short days will shorten time to flower.
FINISH PGRs
TECH TIPS
B-Nine ® WSG at 2,500–5,000 ppm if needed.
To avoid iron and/or manganese toxicity, monitor and maintain media pH above 6.2. If plugs are stretched, plant them deep, up to the cotyledon, to prevent floppiness.
FINISH PGRs
TECH TIPS
Usually not needed. If necessary, spray with B-Nine ® WSG at 1,500–2,500 ppm to control stem elongation.
To avoid iron and/or manganese toxicity, monitor and maintain media pH above 6.2. If plugs are stretched, plant them deep, up to the cotyledon, to prevent floppiness.
FINISH PGRs
TECH TIPS
B-Nine ® WSG at 2,500–5,000 ppm if needed.
To avoid iron and/or manganese toxicity, monitor and maintain media pH above 6.2. If plugs are stretched, plant them deep, up to the cotyledon, to prevent floppiness.
FINISH PGRs
TECH TIPS
Plant growth regulator (PGRs) are not usually necessary. If needed spray with B-Nine ® WSG at 2,500–5,000 ppm.
To avoid iron and/or manganese toxicity, monitor and maintain media pH above 6.1. If plugs are stretched, plant them deep, up to the cotyledon, to prevent floppiness.
FINISH PGRs
TECH TIPS
If needed to control height, spray with B-Nine ® WSG at 2,500–5,000 ppm, Bonzi ® at 15–30 ppm, or Sumagic ® at 5–10 ppm. To help control growth in the retail environment, drench with Bonzi ® at 2–5 ppm or Sumagic ® at 1–2 ppm when plants are up to size and flowering.
To avoid iron and/or manganese toxicity, monitor and maintain media pH above 6.2. If plugs are stretched, plant them deep, up to the cotyledon, to prevent floppiness.
FINISH PGRs
TECH TIPS
Usually not needed, but if needed B-Nine ® WSG sprays of 1,250–2,500 ppm are effective.
Do not bury the seedling to avoid stem rot. Provide good air circulation and do not irrigate late in the day to avoid Botrytis stem infections.
