| One of my bean bushes has suddenly bit the dust, was only a young one, I pulled it out to examine the stem and roots, when peeling back a bit of the stem I discovered that it was full of little thing maggots, can anyone please tell me what the problem would be.

| Karn. When I lived North I had a lot of trouble with bean fly, the young plants would just keel over and die so maybe the thin maggots are the larvae of those fly which tunnel in the main stem and cannot be seen outside the plant. The fly usually lays the eggs in the leaves and small yellow spots develop when this occurs. Did the stem look swollen, cracked or red in colour.???? Young plants wilt, yellow and fall over after the larvae have tunnelled in the stem near ground level. You have to kill the larvea while it is still on the leaf by spraying a insectide on them weekly starting at three days old and continue till blossoming. The only organic control is do not plant beans in the same bed every year, but I dont think you do that. Hoping this is of some help to you ......MM. |

| I've heard, though I can't confirm it, that a good dose of potash helps strengthen beans against bean fly. |

| thank you MM and Ray for your help. I had know idea there was a bean fly, my son use to grow acres of beans for the markets, and he had never come accross it before. This particular plant would have been only 8 inches out of the ground, and started to show signs of wiltering, there was no sign of any insects on or under the leaves, no yellowing of the leaves, the stem seems ok to look at, it was only when we peeled back the stem layer that we saw these tiny thin maggots, and yes this is the first time beans have been planted in this particular garden. |
