*Transplant water treatments based on 200 gal/A water volume.<br />
Foliar applications made at 15 gal/A (early) and 30 gal/A (late).<br />
Threshold is 5 worms per 50 plants (hornworm or budworm or combination of each).<br />
<strong>Coragen</strong> TPW treatments followed up with standard insecticides as foliar treatments at threshold.<br />
Four randomized replications (plots) of each treatment in trial, approximately 50 plants per plot.<br />
PD 7318LC set May 26, 4900 plants/A, fire-cured. Admire Pro (0.75 oz/1000 pl) applied as tray drench.

UKREC, Princeton, KY – Trial Summary<br />
• <strong>Coragen</strong> in transplant water at 5 or 7 oz/A saved<br />
one foliar spray.<br />
• Plants treated with <strong>Coragen</strong> in transplant water<br />
at 5 or 7 oz/A did not reach threshold until 9<br />
weeks after transplanting (July 29).<br />
• Worm control from <strong>Coragen</strong> as foliar spray was<br />
similar to Belt.
