Bottle directions say after.

Duh. Thanks Marsha. Should have read that first, label is kind of like an eye test tho.

My bottle directions for Daconil Fungicide Concentrate does not answer this question. It only mentions "rain-proof protection". Customer service ((866)-945-5033) informed me that Daconil dries and bonds to plant surfaces in approximately 2 hours. Rain will not wash it off once it dries. If sprayed and allowed to dry, it is best to apply prior to rain to prevent spores from attaching to treated surfaces.

Too true! I can't see anything anymore without my glasses.

I only use copper, not daconil, sorry I couldn't answer for that.

Thx per2012, Marsha

Sounds like Daconil before, copper after.

On a related topic has anyone used serenade? I've been having good luck with it controlling grey leaf mold. Don't really get any rain here in SoCal during the growing season. It's organic as well.

I tried serenade for 2-3 years and did not find it to be helpful in Texas. We tend to have conditions that are conducive to disease though, especially in the Spring.

Might as well be spraying water here in Alabama. I used quite a bit of it and it almost seemed the diseases got worse the more I used it and the cost was a bit high. I think the disease pressure is just too great down here for it to be effective. If Gray Mold gets started on a plant down here in the summer you better stop it fast or say good bye to the plant shortly.

Daconil doesn't seem to stay on my plants during a good heavy rain. I think copper stays on a bit better from what I can tell but neither will give you much protection during long rainy spells. They both seem to stay on okay during light showers if they don't go on for too long. I like using the diluted bleach spray during really rainy times and follow with alternating treatments of copper and Daconil about a week apart during the summer when disease pressure is greatest.

Thanks for the tip Bill. I think I caught my Gray Mold early enough for once but There's still a couple of plants that have a few leaves showing signs of it. I'm going to try your diluted bleach spray on those and see if that stops it. I found your post from 2013 with all the details.

Well three days after spraying Bill's diluted bleach solution I've discovered I had more grey leaf mold than I thought on one plant. Most of the others weren't too bad. Thanks again Bill bleach will now have permanent place in my garden arsenal. Time to cut off the dead bits and spray some copper on there. Guessing this is a game I'll be playing for the rest of the season.

Here's a link to Bill's old post about Bleach so you don't have to dig for it if you're interested:
