Potato blight

[Flummery]

Whereabouts are you Suzie? It's VERY early for blight. Are you sure you haven't over-reacted to something else damaging your potato leaves?

I agree that other crops are safe, by the way - it's the spuds and toms that get hit.

Eh? Speak up there.

Oops, missed that you had blight already. Agree with Flum much too early for blight, like to know where you are though?
Have you misdiagnosed sun scorch or something like that?

The link I posted above has another recipe in it for a baking soda mix, although he states he doesn't think it works very well.

Zazen and Peter, do you spray your tomatoes as well? If you suffer from blight on them that is.
I normally manage to get round blight by being extra vigilant and removing the blighted leaves/stalks, I also have been relying on Legend and Ferline the last couple of years to at least give me some resistance, but this year I will be growing Ferline only of the two. Although I have got other varieties as well.
What I am not growing this year is Marmanade (as it didn't ripen) and Russian black cherry as it seemed particularly bad with blight.

Just seen this...yes I do. Outdoor ones. Same principle applies. It seems the only thing that organic methods can't seem to manage....although I am looking at that link you posted to see if there are alternatives.

Hi guys,
Thanks for info re other crops and blight. I am in Clogherhead, a small seaside village on the east coast of Ireland. I am pretty sure blight is the problem and assume its because the tunnel has been quite muggy of late. It is full of plants mostly planted in January and all well on their way and some being harvested for a few weeks now (harvesting spinach, onions, carrots, mangetout, & lettuce so far) . Some of my spuds foliage is about 3ft high and flowering, others, planted a few days later are not quite there yet. I have a row outside also but they are only about 4 inches high so the tunnel has pushed everythin along.

I have browning leaves and stems, particularily where the side shoots branch off. Some of the leaves have gone yellow and some of the patches had gone slimy while others covered in a powdery mildew. I cut off everything affected and removed from the tunnel.

I guess I will just have to wait and see. Its a learning curve.

Blight leaves them black and slimey though.

the big spud brains on our allotment tell me that once the main crop break the surface its a cup of seaweed liquid in a gallon of water, twice a week for a fortnight worth a try
