As some of you may remember I found that baking powder in a spray gets rid of loads of mildew on indoor plants. This is just a reminder and worth a try as I was reading on one post about courgettes indoors spreading mildew!
I have just noticed some starting so will zap that also I used the same spray last year on my aubergines that were looking very sad as they were plastered in red spider mite webs and mites. It worked well - although I lost a few leaves before the plant picked up and got strong again but I didn't have a recurrance of the spider mite.
I used random amounts but probably a couple of teaspoons per litre or two of water worked - so nothing scientific in quantities.
