How can I prevent black fly on Broad Beans?
Posted by Dobies Staff on 24 June 2013 11:35 AM
Once the first beans start to develop pinching off the top 7.5cm (3") of stem will help to deter blackfly. Should the plants be attacked spray them with Bayer's Ultimate Fruit and Vegetable Bug Killer or other suitable insecticide. 

As with all chemicals follow the recommendations on the packaging.
