Ramularia prevention, mid timing fungicide boosts.

[Oldmacdonald]

We had big ramularia problems here last year in both some Winter Barley, and more commonly in spring barley.

The reason is mainly down to a longer time period between spray timings than was ideal. Maybe 4 weeks plus.

My thinking was if I keep my main two applications at the traditional T1 and 2, I could have a small cheap something up my sleeve to nip across with just to keep disease down slightly until T2.

My question is two fold.
1. Is this sensible?
2. What kind of product would you look to for this purpose?

Ask a theoretical question to any forum member with more chlorothalonil in the shed than they can use, asking I for they would sell you some.

Ignoring CTL.

is revysol not going to be the only true option for ramularia control after the ctl ban comes in

Ignoring CTL.

That was it. There's nothing cheap - I'm not up to date on whether folpet is an effective substitute or not. Otherwise, keep your spray interval shorter, azole & SDHI dose rates up and test home saved seed for presence of the disease.
