Norflurazon (Solicam) injury
Eric Hanson, Horticulture
Blueberries are relatively tolerant of norflurazon. Excessive rates cause distinct leaf symptoms. Veins turn white or pinkish white. Current-season shoots may turn white. One-year-old bark turns pinkish. Symptoms usually appear first on lower branches.
Norflurazon is persistent in the soil, so excessive rates may not result in symptoms until late in the season or the following year.
