JKH said:I have had several varieties of daylilies for decades then three years ago I got hit with gall midge.
Right now I have three yellow plants and I had to remove two buds I thought might be infected but it has started to bloom and looks good. Right next to them I have some pink plants and they have the midge. Plants that I have had for 30+ years are being hit the hardest as well as some plants I have had for 20+ years. This year I am not just taking off infected buds, I'm cutting off whole stems. Is there no systemic or something to stop this? This may be the year I dig them all up and find something else to fill the space.
What might be available to you would depend on what is permitted where you live. Are you in Europe, USA or Canada? The link to the AHS/RHS study in previous posts in this thread discusses some pesticides although they were not completely successful.
