ANNUALS | SEED FINISHING
Antirrhinum majus F1 Snapdragon LIBERTY ™ CLASSIC FINISH PGRs If needed, sprays 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. Antirrhinum majus F1 Snapdragon MADAME BUTTERFLY ™ FINISH PGRs If needed, sprays 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.
TECH TIPS
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.

Antirrhinum majus F1 Snapdragon Dwarf SNAPTINI ™ FINISH PGRs
TECH TIPS
If needed, sprays 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.

Antirrhinum majus F1 Snapdragon SWEET DUET ™ FINISH PGRs
TECH TIPS
Sweet Duet snapdragon grown cool and under high light will need minimal PGRs. However, if grown under warmer temperatures when development is faster, 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. Do not apply Bonzi ® drenches after visible buds to prevent clubby flowers
Do not bury the stem to avoid stem rot diseases. Control thrips to avoid TSWV or INSV infections. Sweet Duet snapdragon are not influenced as much by day length. The flower response is more affected by temperature and will flower faster under warmer conditions (up to 68–70 °F ADT).
Begonia boliviensis F1 Begonia BOSSA NOVA ™ FINISH PGRs
TECH TIPS
B-Nine ® WSG (1,500–2,500 ppm) alone or in combination with Altercel ® (750–1,000 ppm) are usually sufficient to control growth. A Bonzi ® drench (0.25–1 ppm) can also be used to control growth or to hold plants for sale.
Day length is critical to achieving the best quality—maintain a minimum of 14-hour days for more showy plants. Do not bury the plug when transplanting to avoid crown rot. Irrigate early in the day to avoid leaf scorch when high light levels are present. Avoid using high ammonium fertilizers since they will promote larger, softer leaves. If planting multiple plugs per container, make sure the leaves are pointed to the rim of the container so that flowers will be more visible.
Begonia × hybrida F1 Begonia Interspecific BIONIC ™ FINISH PGRs
TECH TIPS
For pint or quart production, a Bonzi ® drench at 0.1–0.25 ppm about half way through the finishing cycle will provide excellent control of leaf and plant size. Bonzi ® sprays are not recommended as they will reduce flower size. For pints to 10” hanging baskets, sprays of B-Nine ® WSG at 2,500 ppm or B-Nine ® WSG/ Altercel ® tank mixes at 1,500 ppm B-Nine ® WSG/300 ppm Altercel ® are effective in reducing leaf size and stem elongation. PGRs are usually not required for containers larger than 10” hanging baskets. Plant growth can be best controlled through proper moisture, feed, and temperature management.
It is recommended to avoid high ammonium fertilizers since these fertilizers promote soft, leafy growth and may delay flowering.
