Is this potato blight?

I am fairly sure that my potaotes have been hit by Phytophthora infestans but I just wanted to check with people who may know better than me before I take any action.

Are the brown and dying leaves in the 2 pictures below a result of blight?

If yes, should I pull all the potatoes immediately before the blight spreads?

I have 2 rows- about 5m by 0.3m and about 80 seeds which were put down in mid May. The potatoes are bionica which are supposed to be blight resistant but I was told that no breed are entirely blight resistant.

Cheers.

 

Sorry the photo didn't upload in the OP.

 

Another photo.

 

Personally I dont think it is blight'

 

I don’t think so either. If it is, they’ll go downhill rapidly, so just keep your eye on them to be on the safe side.

 

Don't think it is, but take the affected leaves off and burn them as a precaution.

What do you think @Scrungee ?

 

I've had similar on my spuds most years, its never progressed into anything other than a few tatty leaves, and at this time of the year they are mostly dying off anyway.

 

Far too mild to be an attack of late blight at this time of year in my opinion.

Always worth having a furtle around one of the plants to see whether they're ready for cropping, and if so cut tops and lift spuds in a couple of weeks.

 

Some of mine have similar marks on their leaves as in photo 2. They have had these for a while and not gone racing down hill a la blight. The potatoes gathered from the plants are totally blight free so just think it's the leaves getting old and beginning to look a bit tatty round the edges....like me.

 

@all -

Many thanks for the useful replies. I won't do anything drastic just yet, but may pull a few tomorrow and cut them in half to see if the potatoes are healthy on the inside to put my mind at ease. And of course it's a perfect excuse to maybe eat a few tomorrow.

I first noticed the leaves browning last Saturday. Would it be correct to say that if it was blight more of the crop would be affected by now? Only a small fraction of the leaves are affected.
