We've had two or three very steamy hot & showery days recently. Does this mean that tomato blight is closer to becoming a real reality? I haven't sprayed at all this year yet as a precaution and wonder whether I should now do so just in case? Has anybody else had any blight yet?

Hot & humid = blight.

Check out the Potato Council Fight Against Blight FAB website, which explains the risks etc.

Hello Primrose

The answer is undoubtedly YES you should start spraying using a copper based spray and spray again leaving it no longer than a fortnight between applications. Spray on a dry day thoroughly covering all the leaves. I have grown outdoor tomatoes in four different places each roughly a mile apart from eachother and I have managed to spray three of them and wished that I had got to the other patch before now.

My son who grows potatoes has received several alerts of Smith periods (warm and wet) and has been spraying his potatoes regularly on each warning for weeks now. As you now doubt realise it is potato blight that in turn affects the tomato.

Keep spraying
