Broad bean weevils

  Hello. I live in Dijon and I am in my second year of having an allotment where I currently have broad beans and peas growing. They are being chewed by something I have just identified as broad bean weevils (notches in the leaves) which means I have to add a new beastie-vanquishing technique to my repertoire.
  
  Does anyone have any remedies for discouraging bean weevils? It seems they are not catastrophic for broad beans but peas are more suseptible so any suggestions would be welcome.
  
  Thanks

  How advanced are the beans and peas? The more advanced, the less real damage weevils will cause apart from the chomped leaves. Seedlings are more vulnerable. Something like a derris dust sprinkled lightly on the ground around the plants might stop them.

  I have given by broad bean seedling a generous sprinkling of hot chillie powder, we'll see if the weevils like 'chillie con favas'

  My peas and beans always seem to be attacked and always recover without treatment. I wouldn't bother doing anything other than keeping an eye open. If the damage extends beyond the little nibbles round the leaf margins then do something.
  
  Good luck and regards to Dijon, you must be as keen as mustard! L

  The broad bean seedlings came up about two weeks and one or two are looking a bit feeble which I thought might be due to the weevil. There are successive plantings of peas so anything from just emerging to a few inches high.
  
  Derris dust is pyrethrin isn't it? I don't think that brand exists in France but I'll look for pyrethrin powder.

  No Derris isn't the same but it is "organic". I usually buy sprays rather than dusts. You can buy inexpensive sprayers easily which will give you more options if you have to treat e.g. tomato blight and other disorders.
