    we are in Abbotsford.our cherry trees are forming a white almost powder. It starts on the trunk, unless it is a top graft then the white is starting on the graft. Can be top or bottom or middle of the tree where it starts. It seems to start as spots then become covered. Some of the trees are completely covered but the leaves are fine. So far. We can see nothing on the tree or leaf. We have noticed that the trees in the shade have no white on them as of yet. We have contacted agriculture here in Abby but will not hear from them for a week or two. My neighbour about a mile away has the same problem. I have added some pics to help. 23148D71-0537-4955-94CC-97FEF548EDFE.jpeg 77E374E2-F216-4F39-A209-FCCC66E6613B.jpeg 27BC742F-79C3-49B8-BAD9-15262B23600C.jpeg 7DA44CB5-7B87-4B31-8ADA-EF3EFB4D8D00.jpeg 81913560-FC1F-478B-8962-69096332CB64.jpeg 868B6547-54CC-493E-864D-6CA4A58A2F6B.jpeg FCEEF46C-E12F-41A7-BB14-A037D2A742CA.jpeg 1378652C-CD54-415D-A4CA-BF99ED6A17B7.jpeg BC15A8E3-20E4-45C0-A209-7489891A8FE1.jpeg 45CBEEA3-966A-459D-9673-62FCC2A3F23C.jpeg

    Start by looking for aphid-like insects under each white puff, seeing if those are present.

    Thanks. I did look but I do not have a microscope to see. The white dots are very small. We scraped the white stuff like a soft powder. It seems to have a web like feature.

    What I'm talking about you don't need a microscope. If you can not plainly see insects then it is something else.
