Hi I’ve used it for years for carrots & parsnips against the dreaded root fly, & I now use it for all of the alliums against the allium leaf minor. For brassicas I used to use debris netting until I realised in 2018 that I had not only stopped the cabbage whites, which was my intention, but I’d stopped the lady birds & hover flies etc that might have feasted on the mealybugs that I had an infestation of. I had been going to purchase enviromesh for the start of 2019 but with that in mind I decided to go with butterfly netting.
