We had a great crop of tomatoes last year, everybody else on the site lost the lot to blight. I sprayed with Bordeaux every time there was a chance during that horrid, long wet bit. The most important thing with Bordeaux mixture is to not try saving any once it's mixed up - throw away or use up whatever's in the sprayer at the end.

So that means the half bottle I found in the shed from last year is no good then ???

Thanx, Ollie. Just had someone look over my shoulder and said "I could have told you that"  ::) ::) ::)

I had an alert today in Peterborough, area PE4.

Yep, alert here in Derby emailed to me this evening...... :-\

Pre mixed bordeaux powders are not as effective as one mixed to need, I have tubs of copper sulphate and lime and mix as needed.

However, I am striving not to use them, but no doubt will fail.

Ower Tone has sprayed his taters with Dithane. Fingers crossed

Can somebody tell me where i can get bordeux mixture ???
it doesn't seem readily available,i've tried looking online but they seem to be  lot's of american sites and i'm being distracted by all the wine offers :D

Pre mix powder is not as effective as the raw ingredients mixed when needed. The raw ingredients are copper sulphate and slaked lime.

Why?

The chemicals start degrading more rapidly once mixed than they do when kept separately. The freshness of the slaked lime is more important than that of the copper. I buy copper to last some time and smaller quantities of lime, this way there is less waste.

I can't recommending the spraying of 'copper sulphate & slaked lime' within the confines of an aluminium greenhouse.
Corrosion being the main reason!

Thanks!  I had thought previously about buying the separate components and mixing my own as it's expensive to buy the pre-mixed stuff.  You've convinced me it's a good idea for a different reason!

Thanks grotbag and sholls ;D ;D
