Paul-Emile Yelle told me I was on your blog!<br /><br />Potassium bicarbonate + sulfur is a great apple scab fungicide for organic growers.<br /><br />Applied with the right timing, it has good post infection activity. It's used on thousands of acres in Europe.<br /><br />In our plot, it had great efficacy where kaolin was not mixed in, thus the hypothesis that there was some sort of interaction.
