URC, CC, AutoStix ™

Recommended

CapSil ® (spray adjuvant) can be sprayed on the cuttings at a rate of 2–4 oz/100 gal within 1–2 days after sticking to help in rehydration of the cuttings. Misting should be significantly reduced after 2-3 days and after cuttings become fully hydrated. Not

4.5-5 Weeks 70-74 °F (21-23 °C)

Recommended

Comments: Do not reduce mist too soon during propagation. Continue light misting until all cuttings are rooted into the media. Reducing mist too early can result in slow and uneven rooting across the bench. To keep plants under control, a spray of B-Nine ® WSG (2,500 ppm) or B-Nine ® WSG (2,500 ppm) + Cycocel ® (1,000 ppm) can be applied after cuttings are well-rooted and vegetative growth begins. It is also becoming popular for growers to combine Florel ® (350 ppm) with the B-Nine ® WSG (1,500-2,500 ppm) to increase growth control and to improve branching. These Florel ® + B-Nine ® WSG combo sprays should be applied to actively growing plants and done ideally before pinching. Do not spray B-Nine ® WSG or Florel ® + B-Nine ® WSG tank mixes on stressed or weak cuttings. For all sprays listed above, the mist should be off for a minimum of one hour for the PGR to absorb into the leaf tissue.

Recommended 3.5-4 Weeks 70-74 °F (21-23 °C)

Comments: Sprays of B-Nine ® WSG (2,500 ppm) or a tank-mix spray of Cycocel ® (1,000 ppm) + B-Nine ® WSG (2,500 ppm) are generally sufficient. For all sprays listed above, the mist should be off for a minimum of one hour for the PGR to absorb into the leaf tissue.

3-3.5 Weeks 72-74 °F (22-23 °C)

Recommended

Comments: Dekko has moderate vigor and generally is not as vigorous as many full-trailing petunia types. To control growth after rooting, sprays of B-Nine ® WSG (2,500 ppm) are usually sufficient. A tank-mix spray of Florel ® (350 ppm) + B-Nine ® WSG (2,500 ppm) can also be used to control growth and improve branching. Do not spray Florel ® on stressed or weak cuttings. For all sprays listed above, the mist should be off for a minimum of one hour for the PGR to absorb into the leaf tissue.
