ANNUALS | SEED FINISHING
Helianthus annuus Sunflower SUNFINITY ® FINISH PGRs
TECH TIPS
Apply 3–4 ppm Bonzi ® 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. For more detailed PGR recommendations for Sunfinity, visit www.syngentaflowers.com/sunfinity.
A pinch is required to promote branching and control vigor. After 5–6 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 above the cotyledons left after the pinch can be removed to help promote even branching.
Impatiens hawkeri F1 Impatiens New Guinea FLORIFIC ® FINISH PGRs
TECH TIPS
Usually not required in larger containers. In small pots/packs or under low light conditions spray with Bonzi ® at 1–3 ppm as needed.
Ensure a good scouting program for Thrips is in place. Do not try to grow cool; plant growth will stall under 60 °F (16 °C).
Impatiens walleriana F1 Impatiens ACCENT ™ FINISH PGRs
TECH TIPS
Responsive to B-Nine ® WSG, Bonzi ® , and Sumagic ® .
Use a calcium-based fertilizer and feed once a week at most to avoid soft growth and stretching of plants. Do not let plants go into the night with wet foliage or tip abortion may occur, especially during early stages of growth. Downward cupping or twisting of immature leaves may be caused by overuse of PGRs. It is better to use less water and fertilizer than PGRs to control growth. Preventive fungicide applications for foliar and root disease are recommended, especially in high humidity environments. Subdue Maxx ® , Mural ® , Micora ® , and Segovis ® fungicides can be used in a rotation program to control the common disease problems of Impatiens.
