Well blight has arrived in West Sussex. Despite spraying the warm damp/rain over Sunday morning, Monday night has been ideal for blight to spread. Going to the plot last night to re spray after the wet there are signs of blight of Ratte spuds, quite bad so the haulms will be cut down as soon as I can. Aran Victory, Kestral and Marfona next door all look OK at the moment but I will have a beady eye on them from now on.
Keep your eyes peeled!

I reckon I've had it for a couple of weeks - but refuse to admit it!!
Going on as normal until I'm persuaded otherwise. Sprayed 3 weeks ago & again today.
Which raises a question - if blight is showing on a few bottom leaves, will spraying lessen the risk of it spreading to the rest of the plant - or is it a waste of time??

I believe, and have nothing to back this up other than anecdotal evidence, that spraying will slow the spread on light infestations but when the plant is badly effected then it makes no difference.
I have never grown Ratte before and I am surprised at how it has litterally collapsed in a day or two, it seems to have very low resistance. Luckily I only have one row of it, my major main crop is Arran Victory of which I have 3 rows, would
hate to loose them!

For Ratte:
Low resistance to Late Blight on folliage and tubers as very low to medium.

For Arran Victory
Low resistance to Late Blight on folliage and tubers as low to medium.

Kestral Seems a bit better, Marfona even better.....time will tell!

Thanks.
My 2 remaining are both 'blight resistant' - Milva & Cara.
Hoping!!
I have heard that bordeaux is only preventative not curative, but i swear, last year my tomatoes got blight and when i realized it i started spraying every few weeks and they cropped for a good couple months.
Hmm, I have had a sneaking feeling that a patch of volunteer spuds that I haven't been able to dig up have been suffering for a couple of weeks now. Our site suffers terribly every year, and it is only through using Bordeaux that I manage to get any toms - the first year on the plot, not a one! :(
Blight!!?? Help please. What does it look like? I have gardeners delight toms in the greenhouse and some of the lower leaves have discoloured. Could this be blight?
As you know I am the novice of the year. I have grown toms before in the greenhouse and have never had any trouble but now I am wondering.
Thanks, Lorna
:(
My spuds looking decidedly dodgy too Lorna, will keep fingers crossed!
I'm in West Sussex too, so far everything is looking good but will have a closer look tomorrow when I visit. I hope it stays away, my outdoor tomatoes are looking so good at the moment and I still have 2 rows of maincrop spuds in. One is Cara which is meant to have some blight resistance, I don't want to put it to the test though.
