I dissolve one soluble aspirin to one litre of water, and if I don't drink it straightaway, I start shaking and it gets spilled all over the tomatoes, as I always have a headache when walking into the greenhouse...

Get out of that one, Brussels Sprouts...

I wonder if it works on spuds cos I always get a headache as soon as blight threatens

Certainly does work! I usually trip over several times on the spud patch..;0)

Never stop learning 
ShedM'  the article in the independent  says that it reduces blight by 47% if used before the potatoes are infected.
