Hello, Growers

Winter has arrived, which means it’s time to kick your navel orangeworm (NOW) management program into high gear. Although recent rains are helpful in reducing NOW survival, winter sanitation is still essential. According to standard recommendations, mummy nuts should be reduced to an average of two or fewer per tree by Feb. 1, and mummies on the ground should be destroyed by flail mowing by March 15. Steps for a complete program to control NOW can be found on the UC IPM website.
