TECH TIPS
Spray applications of B-Nine ® WSG at 2,500–5,000 ppm, Bonzi ® at 15–20 ppm or Sumagic ® at 10–15 ppm are effective to control growth; 1–2 applications are usually sufficient. Do not apply Bonzi ® drenches after visible buds to prevent clubby flowers.
High pH levels (above 6.2) may promote iron deficiency causing chlorotic young leaves. Overly wet conditions or watering late in the day can cause shoot tip abortion. Keeping the media too wet can also lead to root rot diseases such as Pythium.

FINISH PGRs
TECH TIPS
Snaptastic is grown cool and under high light, and rarely needs PGRs. However, if needed spray applications of B-Nine ® WSG at 2,500–5,000 ppm, Bonzi ® at 15–20 ppm or Sumagic ® at 10–15 ppm are effective to reduce stretch under suboptimal environmental conditions. Do not apply Bonzi ® drenches after visible buds to prevent clubby flowers.

However, if needed spray applications of B-Nine ® WSG at 1,500–2,500 ppm, Bonzi ® at 5–10 ppm or Sumagic ® at 2.5–5 ppm are effective in reducing stretch under suboptimal environmental conditions. Bonzi ® can also be drenched at 1–2 ppm. Do not apply Bonzi ® after visible buds to prevent clubby flowers.

TECH TIPS
Apply 3–4 ppm Bonzi ® (paclobutrazol) drench 1–2 weeks after pinch; 3–4 ppm drench at first sign of vis- ible buds; 3–4 ppm drench when flowers start cracking color to hold for finish. Higher concentrations may be necessary under high temperature and long day conditions, but do not exceed 6 ppm for each drench.
Apply a Bonzi ® (paclobutrazol) sprench at 2–3 ppm within 48 hours of sowing (3–5 quarts per 100 sq ft.) to control hypocotyl stretch. Plugs must be propagated under long day (+13 hour) photoperiods in order to prevent delays in flowering.
