Hi, I have a small raised bed sowed (Sharpes Express) and usually spray with bluestone mix for blight. Can this be applied with a watering can or do I need to wash out my sprayer normally used for roundup. Would be alot handier to use watering can!

Yes to watering can. Definatly not to use sprayer if it has traces of roundup in it. Why not buy a second sprayer pump action 5lt size for anything other than Roundup.

Aldi/Lidl often do small sprayers, worth it for the job.

Keep tools for weedkiller and non-weedkiller separate.
I'd use a sprayer for blight, but not one that had been used for weedkiller.

Dunno how you'll get a watering can to cover the undersides of the leaves, unless you've gallons of the mix. Still, adhesion may be an issue.
