Have I got blight already?

[Chris Graham]

Take a look at these images.

Is this blight?

Only on one of my strongest "Sun Gold" plants but it is a worry.





I have also updated my website if you want to take a look.

are they not scorch marks ?

[deboydoyd]

Hope so because i've got them too!!

[Tin Shed]

Moved some toms from one cold frame to another more in the sun, and later in the day found similar little marks looking like a rash on some of the  leaves that had been more exposed to the sun. Paniced, then presumed that it was the sun - didn't know toms got heat rash!!!!

[BAK]

too early for blight is it not? notwithstanding the warm weather. Blight tends to come in warm moist conditions. I agree that it looks more like scorch marks.

[Georgie]

I agree that it doesn't look like blight.  Stop worrying.   ;D

I'm with the scorch marks, cos I have them too, some leaves on my earliest sown toms are positively battered what with the sun and the east winds. I bring them in at night and talk to them nicely and they are forming their first flowers  ;D

It looks like you have been spraying or watering onto your leaves, the water acting as a magnifying glass and and scorching your leaves.

But all the books say to spray in the morning? How do you stop the leaves getting scorched?

It's far too early for blight, and if you get it, you won't need to ask.

Not humid enough for blight yet..I agree with the idea of scorch- Water from the base and also the floor.

Strange - I had only heard of spraying/misting toms in relation to the setting of the flowers, & this at midday.

I believe that some scorch can be caused through transpiration droplets rather than spray?

[davyw1]

I agree with you Tim, i have never heard of spraying Tomato plants either, and you will always get water droplets from condensation. If you are trying to create humidity then put tubs of water in the greenhouse, spray the floor but never the plant. When the fruit comes on and you spray the plant it will cause the same result on the fruit as you have on the leaves Ghost Spot ( water Spot )

Hmm, just given the plants in general (including tomatoes) a seaweed foliar feed.

[BAK]

I think that it depends on where the plants are and how they are tended.

In the days before we had cold frames we used to move toms, courgettes, etc from window sill (no greenhouse .. still no greenhouse) to the plot and put each plant under a 5 litre water bottle (bottom removed). Scorching was a regular hazard (a) from condensation drips or (b) from any leaf that was in contact with the plastic (before we noticed it). Affected plants were invariably checked for a short while but always recovered.

[tim]

Yes, sorry - foliar feeding is, of course, a norm.  Especiallly seaweed.

It was the 'morning spray' that I couldn't visualise.

i,v always found the first sign of blight on tomatoes was the green fruit having brown blotches on them. i avoid blight on potatoes by only growing 1sts and 2nds
got blight on pink fir once it was orrible
