Biological control of caterpillars
I grow a lot of brassicas and every year, in spite of resolutions to
patrol them regularly and squish the eggs and caterpillars, I never manage to quite keep up with them - just too much to do mid-week and weekend forays aren't enough. I always feel I'm doing fine, and then from September onwards, gradually lose the battle. I use mesh with partial success but at the moment I haven't got enough to cover all I grow. I'm wondering whether to invest instead in the biological control which seems to be readily available. It is dissolved and watered on, I believe and can be stored for some time, which seems an advantage. Could anyone who has tried it report on its success, ease of use and how often it needs to be applied to keep on top of things? Thanks for any thoughts Janet G |
