How do you plan stopping cabbage whites from damaging your Cole crops in 2010?
I plan is spraying spinosad based pesticide,under planting with white clover and little shade cloth to prevent frost damage in spring.
If you are going to start creating pointless threads about pests & diseases now can you at least create them in the Pests & Diseases (http://www.allotments4all.co.uk/smf/index.php/board,23.0.html) section of the site rather than further cluttering the edible plants section.
Please ....no more,lists.........I have tried to be gung ho about them but it is ridiculous now.........destroying this forum
There can be very little on the 'list' threads which you couldn't find by using search.
You could stand next to them with a fan.
betula and Baccy Man the threads are not pointless. what is destroying the forum is the continual offtopic posts by ace and others.
Did I tell you about my holiday last year ??? :)
here in lancashire we put cole on the fire
would you put this on your allotment?
NO!!

Ahh, an Organic approach to stopping cabbage whites from damaging your Cole ?
jimtheworzel the type coal you on fire is spelled "coal".
As for spinospad it organic as you can get.
compared every other pesticide I can think of.
Do yer reckon thems cabbage whites were responsible for Cole's flappy trousers on Sat night, looked like there was an infestation of wrigglies & was trying very hard to shake 'em out.
Certainly X rated factor.
Spinosad certainly claims to be organic. What I would find a bit concerning about it is the assertion that "spinosad is relatively non-toxic to mammals" and "it is only toxic if ingested ". (my italics)
What exactly do you mean by cole? Brassica oleraceae var. acephale? If so, mine does not appear to be affected but I cover it up anyway to protect it from marauding pigeons.

LOL, I must get some of those trousers, perfect for the next scarecrow.
Forget the jobsworths and trolls. They know who they are.
The problem with white fly is that if you spray, they just move next door where they have not sprayed then fly back again when the spray is gone.
Either spray every week or spray every one elses plot/garden near by at the same time you spray your own.
PurpleHeather white fly and cabbage whites are not same thing.
I follow Terry the hill allotmenteers tip and water all brassicas with water steeped with rhubarb leaves. I didn't do it this year and my brussels and PSB are covered in white fly and there is evidence of CWB babies munching the leaves - that'll teach me...........
I use the rhubarb method - it works for me!
Has anyone tried BT for cabbage whites? There are different forms for different insects. I've used the one for wax moth, and killed the lot with no harm to my bees. If you gather some dead caterpillars afterwards, mash them up in milk, and keep it in the fridge, that'll give you another dose for the next generation of caterpillars.
Robert, I haven't and what is BT???? or should I phone a friend ;D ;D ;D

Bacillus thuringiensis. It's a caterpillar disease you buy in a bottle. The last I heard it was difficult to get, but Certan (the type for wax moth) is still on sale. Maybe I'll try that next year and see if it kills cabbage whites as well.
Does anybody else know where to buy it? I really could have used some whne we got the mass outbreak... :-[
Lost most everythng last year.
This year, netting worked fine.
BT is like myxomatosis for caterpillars.
Probably equally cruel... but harder to get worked up about a "starving" caterpillar than a frothy bunny... :-X
Think I'll stick to the netting :) :) :) Worked this year a treat.

Certan/B 401 is bacillus thuringensis aizawai.
The strain needed to kill caterpillars is bacillus thuringensis kurstaki which is marketed by Fargro LTD & Interfarm UK LTD under the name Dipel DF. It is currently only licensed for professional use in the UK.
