I will be a presenter at a webinar from the Wild Farm Alliance, on March 11 at 11 a.m. #12 on this page https://www.wildfarmalliance.org/whole-farm-spm-course 1 CE unit. Free. My title: Ants and carpenter moths change the canopy and underbark natural enemy guilds of mealybugs in grapes. Devin Carroll David Headrick will also be presenting on pheromone disruption of California Red Scale.

At the AAIE Conference Grape Roundtable I show slides about distinguishing sulfur damage from thrips damage in table grapes. I have more information in two articles on my page: https://sites.google.com/site/devinipminfo/ Sulfur causes "false thrips scars" in grapes. Stamen-Anther Scarring in Grapes; Not Caused by Thrips. The articles also give evidence that sulfur does cause damage. In my thirty years of monitoring table grapes, I have seen far more sulfur damage than thrips damage. A lot of thripicide sprays are unnecessary, and also disrupt biocontrol of other pests such as mealybugs.
