Some of my brussel sprout plants are falling over and looking a bit wilted, some of the lower leaves are yellowing on them too. From what I can gather from Google, it looks like cabbage root fly. We had a good spell of rain the other night so I don't think that it's dehydration, other plants are fine. What should I do now, they were fine healthy plants before the weekend and now they look very sick. I have broccoli, cabbage and cauliflower growing beside them, some are covered by enviromesh, is it too late to cover the others? Is it possible that eggs may already be in the ground around the other plants that haven't hatched yet and if so is there anything I can do to save them? Worried that if I cover them and the flies are trapped under the mesh everything will be destroyed... Please help, this is my first year out and I was so pleased with how everything was growing!

it is possible that eggs are already lpresent and waiting to hatch out. in future put a plastic collar or disc 3 inches in diameter with a hole in centre to fit the stem and a slit from centre to edge (radius line) and slide onto plant at transplanting time, Use flexible plastic or cardboard.
