Just wondering if anyone can help me identify this pest and help me treat my beans. Every time I grow beans they seem to take off and then once they start flowering the leaves start to wilt and drop off and tumourous growths appear around where the leaves join the stems and sometimes at the base of the plant. I thought it was something I was doing wrong the first two times but this time I decided not to blame myself as I planted them in good soil in a position they love. Managed to get them growing really well but then the same thing happened. I picked off a couple of leaves that were wilting and found tiny bugs/larvae inside. They have a brownish/creamy casing and a very tiny - about 1-2mm long. I'm presuming this is the problem but can't seem to find any info about it or how to treat the beans online.
Any pearls of wisdom??
