Alternating between Daconil and Copper
Since I'm not sure which disease(s) I have I thought it would be a good idea to alternate between these two fungicides. Normally you would apply at one week intervals, but because they are different can I apply one on Wednesdays for example and the other one on Saturdays? Or should I stick to the one week interval (i.e. one on the first Saturday and the other one on the next Sat, etc.)? Also, if I want to spray with sulpher occasionally can I do that at any time while the rest is going on?
