Potato spray guide

[mvargovic]

Hello guys,

Anybody has some potato spraying programs regarding fungicides?

I have some issues regarding Shirlan - it is ussualy recommended in late stages and before canopy die out here in Croatia and this doesn't make sense for me since Fluazinam is very weak systemic fungicide?

Thanks in advance!

Fluazinam has resistance issues with some strains so in the UK it is only used with another active.
Go with something that has tuber blight on the label Ranman is useful.

Fluazinam was strong on tuber blight hence why it was used late in the program. It's also a cheap spray at a time in the season that is generally lower risk. However in the UK there are a few blight strains that have built resistance to it and I haven't used it in any quantity for the last two seasons.
