Tomato blight

What's the best way to spray your tomatoes with bordeaux mix, I mean is it dowsing every part, under side and top, or gentle spray. Where do you get it from? Does the fruit just need a good wash off before you eat it? Cheers, Liz (who doesn't want to lose her fruit again this year)

 

Milk is known to work as a fungicide. I use it on cucumbers to reduce the chances of powdery mildew and it seems to work. I'm not aware of any research regarding the effect of milk on blight, but I doubt if it would do any harm and may well help.

Try Googling 'milk as a fungicide' and you'll find a few quite interesting links.

 

I use a fine spray of Dithane and try to cover the upper and undersides of leaves and the stems. If you think back to your last blight attack you'll recollect that the fungus attacks ANY and ALL parts of the plant. Bordeaux mixture and Dithane are not systemic and don't get into the plant/fruit but they do need to be washed off before eating.
Bordeaux mixture is a copper based solution and as far as I can tell may be less environmentally/human friendly than Dithane, though opinions regarding this vary.

There's quite an interesting article here >

and loads of other stuff on the subject on the internet.
As for myself, I'm sticking with Dithane as and when and if I need it.

 

Hello,

This is my first post so excuse me if I'm stumbling around, not a user of forums. I am growing various tomato plants and am worried about blight, I also have potatoes in containers.

I am hoping there is a picture attached to this and someone might be able to let me know what the issue is. The plants are outdoors, and got caught in heavy rain a couple of weeks ago. The leaves may also have been splashed with seaweed fertiliser.

Are these papery brown spots damage or something more sinister?

HELP!!
