This product is a patented, fixed copper fungicide, made by. combining a soluble copper fertilizer with a fatty acid. The copper and the fatty acid. combine to form a copper salt of the fatty acid, known technically as a true soap. The. copper soap fungicide controls many common diseases using low concentrations of. copper. The net result is an excellent vegetable, fruit and ornamental fungicide.

I'm thinking of using a regular fungicide this year. There are many out there. Some work on fungus and bugs. Some are copper-based. They all seem to require spraying every 7-10 days + after rain. They can also get pricey.

Spray every 7 days when the amount of disease. is increasing rapidly. If possible, time applications so that 12 hours of dry weather follow. application. On plants that are very susceptible to powdery mildew, such as home-. greenhouse-grown cucumber, it is best to spray the plants twice a week during the first.

Soap-Shield Flowable Liquid Copper Fungicide from GardensAlive. No personal experience with it although I have been reading quite a bit about it as I'm considering it for this year to alternate with my regular Daconil spraying. The alternative one I'm considering is the Actinovate.
