SEED FINISHING
FINISH PGRs
TECH TIPS
Drench with Bonzi ® at 1–3 ppm as needed to control growth. Also responds to sprays of Bonzi ® at 10–20 ppm or B-Nine ® WSG at 3,500–5,000 ppm.
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. Pinching Obsession Cascade Verbena will create the fullest looking plant but will increase crop time by about ten days.

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

TECH TIPS
If needed sprays of B-Nine ® WSG at 2,500–5,000 ppm or A-Rest ® at 2–4 ppm may be applied.
Start with a disinfected growing area and keep media pH below 5.8 to help avoid Thielaviopsis infections. Control thrips to prevent INSV or TSWV infections. Do not try to finish Vinca early in the North since the plants need high light and warm temperatures to grow adequately. Plant growth regulators (PGRs) are usually not required except in pack production. Never apply Bonzi ® to vinca as leaf spotting may occur.

Start with a disinfected growing area and keep media pH below 5.8 to help avoid Thielaviopsis infections. Cora Cascade’s disease resistance is targeted to aerial Phytophthora which is a serious landscape disease in southern climates. It may have higher resistance to other diseases but is still susceptible to Thielaviopsis. Control Thrips to prevent INSV or TSWV infections.
