Hi,

Can any recommend a good cheap Blight spray? I want to stock up before this good weather breaks.

Cheers in advance

I would be very interested in this as well as my spuds in the ground ( have some also in raised bed) were late going down and are going to be at a higher risk.
Thanks!

Diethene - being withdrawn from sales next year so stock up on that - a small tin will last years

Copper sulphate

Make horsetail tea

If dithane is being withdrawn, there must be a good reason... Does horestail actually work as a preventative fungicide, rather than just a contact?

Copper sulphate as recommended by organic growers is one of the most dangerous chemicals for use in the garden. Horsetail may contain some toxic material which in small quantities is harmless but is dangerous in cumulative amounts. Every spray no matter what its source is will have some effect on the plant and on whoever eats it. Chemicals on the approved list of the Dept. of Agriculture are "safe" when used according to instructions. Those not on the approved list are not.

Thanks for the replies. I managed to get the last remaining tin of Dithene 945 in Woodies, Drogheda. I tried a few other places and they had none. Some of the shops told me they had ordered it but the suppliers had warned them it's in short supply this year. Most never received any.

I think we'll be sowing the few blight resistant spuds or sowing earlier and coping with frost. Was reading how you can start them off under cover in pots for transplanting out later. Of course you have the frost problema nd have to cover. But could be a good way to do it if you have a small enough plot and use a good storer.

I have 3 or 4 sachets in the shed from a couple of years ago if you want them i can post them out to you. I used one and then said "what the hell am i doing" ? to the the potatoes and stopped using even the first mix. might as well buy them in a shop , but each to their own, i'm not saying you're wrong it is just not for me and i'll post them to you tomorrow if you pm the address to me, no problem.
regards, Ian.
