They rarely do get infested by fruit fly but it can happen. The evidence of strike can be found on some of mine but they hardly ever develop and ruin the fruit. I don't use any netting or precautions at all for eggplants and I might find 1 in 30 with a fruit fly maggot (I just bag it and bin it if I find a bad one).Did your egg plants get hit by fruit fly at all?
That's a shame you're allergic to tomatoes etc does that include derivatives like tomato sauce?Nice one. Chooks like infested egg plants a lot. I am allergic to Tomatoes, Capsicum and most nightshade family plants. I can eat Spuds but never two days in a row. So I love to grow them all but I cannot eat them all. Sounds like you enjoy growing them too!
