#1. Destroy mummies on the orchard floor by March 1.
#2. Hang navel orangeworm (NOW) egg, peach twig borer (PTB) pheromone and NOW pheromone traps by March 15. NOW egg trap how-to at: http://ipm.ucanr.edu/PMG/C003/m003bceggtrapsnvl.html. PTB and SJS pheromone trap info at http://ipm.ucanr.edu/PMG/C003/m003bcphrmontrap.html.
#3. If mating disruption is part of your IPM program for NOW, deploy dispensers by late March (or early April). In areas where the wind blows from one predominant direction, traps should be placed so there is a higher density of traps on the windward (upwind) edge of the orchard. Find more info here.
#4. As a courtesy, consider informing your almond, walnut and pistachio neighbors about mating disruption use in the area, as NOW pheromone monitoring trap catches may be affected in areas outside of the treated orchard.
#5. Apply N by late February or March. Approximately 20% of the year’s predicted nitrogen needs should be applied in late February or March.
#6. Start your K fertilizer program in late March, if your K program utilizes in-season injection application.
