Alternating between Daconil and Copper

gman68558(z10 So Cal)July 18, 2012

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?

I use all of the products you mentioned. You need to be very careful with sulfur as it does not mix well with certain products. Been a while since I used it but I think anything with oil in it, needs 30 days before using sulfur.

It is my understanding that Daconil is more effective for fungal issues than is copper and that copper is usually used as an organic method in place of Daconil. So I would just stay with a one week schedule of Daconil to be most effective against fungal diseases.

I sometimes mix the two together in the same tank with fine results.

I think I have heard Carolyn say not to mix anything with Daconil Maybe she was talking about a sticker. Cant remember the context.

Yes Linda, she has talked to the makers of the product and they specified that NOTHING should be mixed with Daconil or the coverage of the product on the leaves will not be 100%.
