Leaf spot disease

Question:

First fungicide was timely and we used Aproach Prima. Second spray was delayed 3 weeks due to rain. Used Provost Silver Second. What should be used this time? Fontelis?

Jordan:

That is okay. Would follow up with a second Provost Silver after Fontelis on a shorter interval.

Follow Up:

Would you go with Provost Silver back to back?

Jordan:

I would break it up. Avoid Chlorothalonil and Miravis because of the delay. Priaxor, Lucento and Revytek would probably do okay. Hopefully, the Provost Silver was able to create a situation where the pathogen has been suppressed.

Follow Up:

Since I’m going follow with Provost Silver on a shorter interval, would you only use a pint of Fontelis?

Jordan:

Use the full rate. We are looking at overlapping protection and any curative action we can possibly get.
