FINISH PGRs

TECH TIPS

B-Nine ® WSG at 1,500–3,000 ppm if needed

Keep under short days for 2 weeks after transplant to allow plants to bulk, then extend the day length to 14 hours to induce flowering. Keep plants on the dry side to avoid soft growth that is prone to Botrytis and soft rots. Highly sensitive to Tospoviruses (INSV and TSWV), so it is imperative to control thrips.

FINISH PGRs

TECH TIPS

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.

Handle plugs gently when transplanting since Snapdragons have relatively weak root systems. Do not bury the stem to avoid stem rot diseases. Control Thrips to avoid TSWV or INSV infections. For early crops grown under short days, provide day extension lighting. Grow cool and under high light for the strongest stems.

TECH TIPS

If needed, spray 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.

TECH TIPS

If needed sprays 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.

FINISH PGRs

TECH TIPS

Apply 3–4 ppm Bonzi ® (paclobutrazol) drench 1–2 weeks after pinch; 3–4 ppm drench at first sign of visible 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.

A pinch is required to promote branching and control vigor. After 6–7 nodes develop on the stem, pinch shoot tips leaving 4 nodes. The nodes of Sunfinity are opposite so a pinch to 4 nodes would leave 8 leaves. This is a hard pinch. The top 2 leaves left after the pinch can be removed to help promote even branching.

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.

TECH TIPS

Spray with B-Nine ® WSG ® at 2,500–5,000 ppm as needed.

Verbena is very attractive to thrips and they can infect the plants with Tospovirus (Tomato Spotted Wilt Virus or Impatiens Necrotic Spot Virus) so start with an effective scouting program and start a thrips control program as soon as any population is detected. Supplemental HID lighting under short days or during cloudy weather will hasten flowering.
