Black fly on tomato

Small black & green flies have appeared on my tomato plants in the greenhouse. What can   I do?

    The black "flies" could be flying aphids, Patricia. They're not uncommon around toms. For that matter, the green ones could be the same. Hard to know without seeing them. Either way, you could mix up an organic garlic spray or use a commercial pyrethrum spray. They work on contact so you'd need to hit the actual insects.

    Up to now I'm currently aphid free in my greenhouses. I always have yellow sticky traps to see what's getting in there.

    In the past I have put marigolds in as companion plants. This year I wondered if the smell of curry plant might work as a deterent or mask the smell of tomatoes as nothing seems to bother it outside.

    I've put pieces in water filled pop bottle inside and up to now no aphids, might just be luckimage
