Growing local

With no beans in just now I had forgotten what a pest Bean Fly can be. So I had a small wander around the 'net in search of inspiration. And Linda mentioned a circumstance of which I have never heard ... Bean Fly eggs within bean seeds.

There's a few links which describe our BF but don't give much additional information. Here's a spray I found ...

'Organic Bean-Fly Spray.'
10 cloves of garlic, un-peeled and cut up rough.
2 onions (as above).
6 hot birdseye chillis, cut in half.
Boil all this for ~ 10 minutes, and let stand overnight. Strain, then add a bit of liquid soap, then store in a glass bottle or jar.
Dilute this, ~ 200ml of mixture to 9 litres of water.
Spray as soon as they germinate, then every second day until the beans are ~ 300mm high.

I'm interested to know what BLF members do to discourage Bean Fly.

One advice I read was to spray the seedlings with diluted Seaweed extract and to add compost.

In the course of my cyber-wander, I saw a photo of some rather twisted mature bean pods. That I've seen now and then and apparently it's a shortage of boron (use Borax diluted and watered on with a watering can).

I'd like to know more about the Bean Fly and about its relationship to bean seeds.

Here's some links ... http://www.daleysfruit.com.au/forum/bean-fly-control/;

I though the bean fly had gone with the colder weather but just visited my patch & they are back again. Just happy I've planted a lot of beans in my 'whitehouse' that seems to be keeping them out.

That's so ... trouble is, Snakebeans are not that juicy nor great raw :-( so I've stopped trying with them and grow the Dutch Pole Beans and now that Jane has sent some of Bob's Beans, give them a whirl too. Getting some of that agricultural cloth and covering the plants until they are bigger (now that I know they do not need the services of bees to make fruit) might shut the bean fly out. We'll see!

Another way to combat bean fly is to grow something they do not bother much. Snake beans are that thing and they will grow well in Brisbane from about Sept through to around May. Snake beans do best in hot humid environments, but will also do fine during our spring and autumn seasons.
