Not in BC
Necrotic Ringspot
Tobacco ringspot virus – TRSV
Not established in BC. Included so growers and scouts can watch for it. Report a suspected find to the BC Blueberry Council.
Damage
Symptoms vary among cultivars. Leaves may be small, misshapen, crinkled and have small necrotic spots, 2-5 mm in diameter. Young twigs may have small brown necrotic patches. Yield is reduced. Symptoms are similar to those of ToRSV.
Disease
TRSV is spread by dagger nematodes (Xiphinema spp.) from infected to healthy roots in the soil. It causes plant decline in Oregon and the Eastern US.
