Anyone know a cure? please....I've google it and all I've found out is what it is..and the cure being Bifenthrin a chemical...but cannot find a product on line that states it is in the product...hope that makes sense.....Or better still does anyone know of another means of control or cure....cheers in anticipation....

They nibble the edges of the broadbeans, but I've not found that to cause a problem, certainly not once they've grown a bit.  If you need to treat can you still get derris?

If you want to know which pesticides contain bifenthrin then go to:
https://secure.pesticides.gov.uk/pestreg/ProdSearch.asp
Type bifenthrin in the box marked active & it will show you a list of the 24 currently approved products containing it along with details of the marketing companies & approval expiry dates etc...

If you need to treat can you still get derris?

Derris was withdrawn from sale in October 2008, all stocks of products containing rotenone people had at home had to be used or disposed of by 10th October 2009.

I wouldn't touch any pesticide with a bargepole unless it has been in use safely for decades.

Certainly not for a 'pest' like pea/bean weevil which causes very little damage to the crop.

So far I don't think a single synthesised chemical has passed this test, and every single one has been removed from sale on health grounds (or will be as soon as we have any experience of it).

Rotenone/derris has literally centuries of well-documented use in the human food chain (used to stun fish for eating in Borneo etc.). It was removed from sale simply because there was no money to be made from it.

As it happens derris is a natural product - that's not the issue (so are belladonna and strychnine) - its safety comes from its rapid loss of effectiveness and that tends to mean a molecule degrades to something that isn't persistent either.

The problem with engineered poisons is that  the more persistent they are the more money they make.

Glysophate benefits from its degradeability (if you make it with dirty water from the butt it simply doesn't work) but I suspect its days are numbered.
