Title: Aphids in my polytunnel
Post by: brotherdeal on June 09, 2011, 20:45
Hi all, it is my first year with a polytunnel and there are alot of aphids all over my chillies and pepppers. What are my options to get rid of these? I know ladybirds eat aphids but i have only found one to put in there, it's never going to eat all of them.

It depends on how many plants you have, how much time, and if you want to be organic or not.
I have few plants, in my back yard, so I tend to go out every day and squish them by hand. Eventually, if you're patient, you win.
If that's not feasible, you can buy ladybirds or ladybirds larvae that can control the invasion (I had some ladybirds larvae in my garden this spring, and they did a wonderful job on the plants invaded by the aphids).
Otherwise, you can find a lot of specific sprays in garden centres, or make your own with water and a bit of washing liquid (search the forums for precise doses).

If organic try biological controlls for them, you can buy them over the net.

If inorganic  :lol: use sprays/pesticides :nowink:

spray with water with a little washing-up liquid in it......you'll have to repeat it though

Its a bit too hot for ladybirds and their larvae in greenhouses/ polytunnels this time of year. A soap spray and also plenty of water for the crops so they are not stressed.
