What was the "additive" you bought for the Cleary product? I assume this was something to make it stick to the waxy iris leaves as normal sprays seem to fall off. Are you using a tank sprayer? If so, what size? Mixture would be 50/50 (water/cleary plus the additive)?
I have had a severe leaf spot issue in the Spring and it showed back up two weeks ago. Not much I can do now, but want to be ready to go in the Spring. Thanks.
