I alternate between chlorothalonil, liquid copper, and Serenade. Like gorbelly noted, it seemed that the Serenade was the most effective this year against the bacterial speck/spot, especially on the peppers.

I've always favored the copper formulations that were 10% copper soap, especially Soap-Shield. I see that the Southern Ag brand that was mentioned is "copper ammonium complex". Does anyone have any experience using both kinds, and which seemed to be better?
