1Question mark (?) means relative susceptibility not established; + =
slightly susceptible, ++ = moderately susceptible, +++ = very susceptible.
2Sulfur injury can occur on tolerant varieties when temperatures of
85F or higher occur during or immediately after spray application.
3 Berries are not susceptible.
