Any ideas what this is on my corn salad. It is a white film or thick dusting. It is only on my Corn Salad (Lambs Lettuce) both in the conservatory and the house (windowsill) plants. No other plants are effected. Thank you JB

I've never grown corn salad, but that looks very much like powdery mildew, which I have had on cucumbers and courgettes.  Joy Larkcom (in her book Grow your own Vegetables) recommends improving ventilation, if the crop is grown indoors.  I have used a bicarb. of soda spray, but this only really stops the condition from getting worse, it's not really a cure - sorry!

Hi JB, 

I think it maybe Powdery Mildew; if so these links may help.

Oh well if it is powdery mildew it is only attacking the Lambs Lettuce so will have to stop growing it and make sure it is not in mixed leaf seeds.     Thank You JB

I agree looks like powdery mildew, I usually get it on my peas in dry conditions. Didn't get that this year but got pea maggots instead aargh

Mildew- throw 'em out and clean up wherever they were growing- I would suggest trying sowing more thinly in future.
