FINISH PGRs
TECH TIPS
If grown cool will likely not require plant growth regulator (PGR) applications. However, if needed spray applications of Bonzi ® at 10–15 ppm or Sumagic ® at 5 ppm are effective in controlling stem elongation.
Provide long days and 68 °F (20 °C) average daily temperature for fastest flowering and finishing.
FINISH PGRs
TECH TIPS
B-Nine ® WSG at 2,500–5,000 ppm, Altercel ™ at 750–1,000 ppm, Bonzi ® at 5–10 ppm or A-Rest ® at 3–5 ppm.
Use calcium and nitrate-based fertilizers to maintain pH above 6.1 to prevent iron toxicity symptoms. Additional applications of magnesium sulfate at 1 lb. per 100 gallons every three weeks is recommended to help maintain healthy, green color. Warm temperatures and high light levels will accelerate growth and flowering.

VIGOR TIMING MPR
B-Nine ® WSG at 2,500–3,500 ppm or Bonzi ® at 5–15 ppm. Bonzi ® drenches are not recommended.
Providing cool temperatures, high light and ‘growing on the dry side’ will help keep Petunias more compact. Early morning DIF treatments also help. Providing long day lighting during short days will shorten time to flower.

TECH TIPS
Responds well to B-Nine ® WSG sprays at 2,500–3,500 ppm. Bonzi ® drenches at 1–2 ppm during later stages in the crop will reduce stretch and will not affect flowering as much as B-Nine ® WSG.
