Fungicide Program
Here is what I used last year in the vineyard. Planning to use similar this year.
In planned order of use through the season...
- Sulfur (kumulus) (1st, 2nd maybe even 3rd applications)
- Vivando (pre bloom)
- Luna Tranquility (bloom)
- Gatten (post bloom)
- Potassium Bicarbonate & Pure Spray Green Oil (late season)
- Serifel (veraison onward)
I tend to lean toward OMRI or natural products after veraison.
I also have Fullback but I'm reading it's got great curative properties so may leave it out of the program unless I have a mildew outbreak. Also reading Gatten has good curative properties?
For an outbreak I usually spray PB & Oil and follow up very shortly after with something like Fullback.
Any insight, experience, especially with the prevenatitve/curative properties of any of the above, most welcome.
I'm also toying with the idea of running 100% sulfur on a vinifera block to see how that fares. We have high disease pressure in our area so I would have to spray Kumulus every 7 days, likely.
