Thanks for all the replies to my problem. I sprayed my Roses and Tomatoes 2 days ago. We had bad storms last night so I will spray the baking soda solution again as soon as every thing dries off. The dang stuff is showing up on every thing. I have noticed it is on some of the broad leaf weeds in my yard. I usely plant my cucumbers under a section of fence I put up for them to grow up on. I love my home made Pickle's, so I know I would be fighting a loosening battle this year with them. I have been raising a garden or been around one all my life and this is the first time I have seen this problem. Last summer Blue Mold hit my cucumbers late in the fall. I new what it was from raising tobacco before, we always use a bleach solutions to spray for it. It would be visible when you went to strip it in the winter, but this problem has got me stumped. So thanks again for all your help.
