| Re: Vine weevil attack - advice needed Thanks, haven't seen that site before. I have done some more research on various sites and the solutions aren't easy.
The nematodes need warm soil (over 4 or 5 degrees) but weevils can start their evil work at lower temps. So maybe delay applying them until spring gets going but you may lose some plants.
The drench can be effective but one site said that the chemical in it might be implicated in colony collapse disorder in honeybees. The drench is taken up by the plants, so mustn't be used on edible crops.
You can use foliar sprays on adults in the summer, but I guess with the same possible problem for bees?
There used to be a compost with the chemical impregnated in it, but it's not marketed now.
Centipedes are natural enemies. Weevils especially like primulas, sedum, fuschias, impatiens and cyclamen - which explains the fate of my impatiens a couple of years ago!
I'd still like to hear from anyone who has tried nematodes, as they seem the most wildlife friendly solution? Sarah |
