Allotments 4 All

Blight has reared its ugly head on our allotment site again. One plot holders spud have been severely affected and its rapidly spreading. 😭😭 The strange thing is there have been no blight warnings which I normally receive via email. how does the blight warning system work? It's such a shame as one new plot holder is thinking of giving up his plot after only one year. I have seen the early signs on my allotment tomatoes which I will remove today. a lot of my potatoes are Sarpo Mira so we will see how they perform. My pink fir are showing early signs though.
I AM NOT HAPPY😡😡😡😡😡😡😡😡😡😡

Unfortunately there is little you can do whether you get early warning or not. Here in SW we get blight every year in early July. To get a crop of early potatoes I try to plant late Feb if possible, then harvest crop before blight becomes a problem. Sarpo Mira have proved reliably resistent here but they are not to everyone's taste. More blight- resistent varieties are being trialed each year and that may be the way to go for growers in blight prone areas.

Same here but mostly on toms.  I will always get blight at some point but not the first week of July.  It has been terrible season and this seals the deal.  I have sprayed mine with some cooper fungicide and cut down a couple of plants but I m not overly hopeful.

I've got the first signs in the poly tunnel but everything outside is fine. Must be the warmer temps inside. I'm kicking myself though because the spores need free water to germinate and I had been so careful to water only the soil and not the leaves, but I got a new hose and gave everything a good spray last week and hey presto now have brown spots.
So my advice is don't let the leaves of your indoor toms get wet if you can.

ssshhhh! fingers crossed.....

Noticed brown spots on one of my tomato plants about a week ago.  Stripped the leaves off.  Funny only the one plant seemed affected and the others of the same variety appear to be okay.  Wondering if I strip the leaves down to just four leaves, that might help. 

here on the sunshine coast its the same a lot of people have had to take up all there tomatoes ive been spraying mine since early june  only lost two plants so far out of 120 i side shooted and sprayed this morning no sign on the other plants   potatoes  are all ok only got sarpo mira left the rest  earlies and second earlies all harvested well always get blight but this year its very early last year it was late september before it arrived

So sorry to hear - only a matter of time before it gets here 

Blight questionaire.
Have you registered with blightwatch.co.uk?
Have you had a smith period for your area (now by post code)
If so, are you able to determine how many days between forecast and  the appearance of syptom upon your plants?
Did the symptom noticed occur on both potato and tomato on the same day, if not, which was first and how long before the second?
How many days did you leave between first and reaction?
What action did you take?.
Has the crop been destroyed?
How was plant material disposed ?
Were adjacent plots similarly affected on the same day(s)

I haven't had any blight warning notices this year, but one of our members reported it last night. Usually get so many notices before any actual signs show up, so same as you Duke. I wonder if the warning system has been deactivated?

Got an alert about a month ago but I think it was for the allotment postcode.  Checked yesterday and spuds seem to be okay.  My tomato plant was in the greenhouse but, as said, only the one affected.

Blightwatch revamped their site earlier in the year which might be why you haven't been getting email warnings if you didn't update your details with them.

Sorry to hear that Duke.

Where's the questionnaire from Ancellsfarmer?

I have a horrible feeling that what I thought was Magnesium deficiency might not be :( Leaves were yellowish before

I treated all with Epsom salts before working away last week...came back to this on tomatoes in greenhouse. Oddly enough leaves going brown /dead on Stevia.....vainly hoping I've made mix too strong and this isn't blight.....no sign on outdoor spuds.




What do you think folks :( sorry to hear you other folks have it.

Hector yours looks more like magnesium deficiency to me...but I'm not an expert.

Thanks Duke. I've removed any odd leaves and will monitor. Sorry to hear you have had blight :(

Agree with Duke, deficiency not late blight.

I've been the prophet of doom on site for the last month but fingers crossed not yet!

Saddad I think you have been more like....

duke this is what it looks like after I've sprayed in answer to your pm   hope it helped
