Blightwatch 2015
« on: May 07, 2015, 19:00 »
DON'T PANIC!!!!    There no outbreaks shown yet, but with an eye on the current damp weather, and it warming up, I thought it worthwhile starting this year's thread.

Blight map here:

http://www.potato.org.uk/fight-against-blight/blight-incidents

There is general information in the Growing FAQs and other Information section on blight, but some of this is now out of date with the withdrawal of the products mentioned therein, but I've currently left it in as there will still be some floating around.

Did it really tell you to do THAT on the packet?

Well, it has actually started to warm up again, but as they say it's and ill wind........ With a cooler spring, there are still no reported outbreaks. This time last year, there were already quite a few dots on the map and we were getting Smith Period warnings.

Didn't quite make it into June unscathed, but there's still a chance as it's currently just a suspected case in the Shrewsbury postcode area.

Not sure I have  ever suffered from potato or tomato blight.
But just tried that map, selecting the SE map.
Does not seem to show anything, its a bit small to use or see anything anyway.
The id/outbreak/variety/reported/source/area/result black up/down buttons at the bottom do nothing.

The buttons have nothing to show until blight is reported, anyway.

Are you looking at it on a PC or laptop - cos it's not a bad size map on my laptop  :unsure:

On the biggest I have at the moment, a 21" screen (1600x1200 resolution) its a 4" by 4" map.
There does look like a lot of tiny dots, but none seem selectable.

Would be a better idea to have it pinned on a google map.

You can always use the zoom if you would prefer it bigger.

The small black dots are just to mark the towns, any blight warning dots are coloured and easy to see, when they occur.  :)

Take some pictures, perhaps we can tell you what is there, but I doubt it's blight as there is no confirmed or suspected blight in England yet.

Look at the link in the first post above.

Ok , I will try to remember to take one tomorrow if it is not raining. I did ask some people in the allotment and they told me that was blight.

Looks, to me, like it may be Target spot (Early Blight) which is nowhere near as bad as Late Blight.
http://www.suttonelms.org.uk/pot62.html
and
http://jbaseedpotatoes.co.uk/info/potato-pests-and-diseases/target-spot-potato-disease/

Late blight tends to look a bit wet, with a white fungal ring around the dark patches, with black patches on the stems and the plants collapse within days.

I'd pick off any affected leaves and see what happens over the next few days. If they do start to collapse then strip the tops off completely and burn or bag up for the tip (don't compost them) Leave the potatoes under the soil for a couple of weeks and try to dig up on a dry day.

Good luck
