PRODUCTION POINTS FOR POINSETTIAS
With fall quickly approaching, poinsettia production is gearing up. From propagation through finish,
it is important to watch for common insect pests, particularly whiteflies, as they can build up quickly.
Syngenta has developed an agronomic program for poinsettia production that provides proven recommendations to prevent pests
and diseases that can impact the quality of your crop. It proposes control options based on their strengths, modes of action and
length of control when they will be the most beneficial.
The following excerpt from the poinsettia agronomic program provides recommendations for the first seven weeks of production.

Apply as a spray to run-off
when conditions are favorable
for disease development.
Apply as a foliar spray to the
point of run-off.
Drench volume should be sufficient
to thoroughly wet soil media without
overflowing or leaching from the
container. Irrigate carefully over the
next 10 days to avoid loss of active
ingredient from the container.
Application Notes
Apply to all surfaces where insects
may breed (potting media, benches
and under benches). Repeat as
needed every 7-14 days.
Apply as a foliar spray to the
point of run-off.
Apply as a drench using enough
solution to wet the root zone of plants.
