Blueberry Leaf Curl and mottled bark on newer shoots

Asked May 3, 2019, 4:46 PM EDT

Mature (8-9 y.o.) blueberry bushes, 6 plants - different varieties, (previously very healthy) have problem with leaf curling. Started 2 weeks ago on early variety; leaves curling up. Nothing inside or under leaf. Leaves curled then turned brown. blossoms also turned brown. Bark on newer shoots looks mottled, "almost fungus-like." It is spreading from bush to bush. First bush affected is now putting out new leaves, but no new blossoms. Careful inspection of bushes revealed one small area of spittle with black insect on one leaf. Also "a few" strands of web filaments noticed. No photos available.

Hello,

Without looking at plants my best suggestion is to send some samples to the plant clinic for a correct diagnosis.
