On May 28, we deployed two traps for San Jose crawlers on each of two trees in my Empire block here on station. Today (June 4) we found crawlers in all four traps. Products in our Spray Bulletin that are rated as excellent against San Jose scale crawlers include Centaur and Esteem. Products rated as good against this pest are Admire Pro and Pasada (imidacloprid), Assail, diazinon, Leverage (imidacloprid + beta-cyfluthrin), Movento, and Tourismo (buprofezin + flubendiamide).
Until next time, best wishes – Chris
