Virtual “Tent Talks”

In lieu of our traditional, in-person “Tent Talks” at the field, we held a Virtual “Tent Talks” on Wednesday, August 19, 2020. The event was well-attended with wide array of topics including, precision planting experiment on cotton, planting a new alfalfa crop, plant growth and development information in cotton management decisions, hemp diseases, predator thresholds in cotton insect management decisions, and management of sugarcane aphids in Arizona sorghum. The event was also livestreamed on Facebook.

In response to the many requests, we made the presentations and videos of the event available online through the following links:
