The high cost of fungicides

[shrewsbury]

Harvest is in October, so I will be spraying just once or twice with sovran at the end of the season. So I will only spray sovran twice in a row at the end of the season.
I rotate each spray during the season, so no product is used twice in a row.
But all well intended advice is worth looking into. I appreciate your input and will do some deeper investigation on this.
Thanks

One way to save some money is to avoid sprays when the environmental conditions are not conducive to infection. For Powdery Mildew many growers use the Gubler -Thomas Powdery Mildew Risk Index which takes weather data and tracks daily risk of infection. The Pest Prophet app (Link) is the a free app which allows to track Powdery Mildew Risk on your phone.
