Potato blight - Smiths period commencing?
United Kingdom
Hi all,
The weather forecast looks quite dire for the Midlands over the next 10 days from a potato blight point of view - with rain producing the high humidy and the predicted warm temperatures offering the chance of a Smith period and the risk of blight to our potato and tomato crops!
How long does an anti-fungal spray need to be on the foliage prior to rain for it to be effective?
Here's hoping it won't be a blight fright night for any of us!

I would think that it just has to have time to dry on. Never heard of a Smith period, what's that?
