Mystery of the missing blackfly on my broad beans
« on: July 10, 2021, 09:52:17 »
No blackfly AT ALL on my broad beans this year. I always have blackfly. I do not use chemicals or sprays at all, and rely on pinching out the tops - which I have not done this year.... I almost miss the little pests (not). Lovely crop of beans. Same places as usual within the plot. Planted indoors to avoid the depredations of the local rabbit population (bigger this year than ever) and planted out over four or five weeks in early May in (home) compost strips between cardboard paths.

No change in nearby sycamore hedge which has always been blamed for the infestations. I would like to know why so I can ensure it happens again for next year! Also no cabbage whites seen flying around after expensively covering all brassicas with veggie mesh on supports. All very odd.

Only other change is not mowing nearby grass since early May except for paths eg to greenhouse. Is this somehow trapping the pests? Diverting their attention?

Any ideas welcome - as I say, I want to ensure this is not the last time this happens!
