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.
