I planted the few survivors out at the end of March which is way too early here. On cold nights and through several frost I covered them with terra cotta pots. They have all survived and are starting to look better. I think the forced air heat in my house was just too much.

It was also only affecting two of my new varieties, but these are also the only ones in plastic pots. The rest I have in little peat pots. Water is probably not evaporating fast enough on those compared to the peat pots which dry out faster, and that issue was probably compounded by the fact I had to bring my whole setup up from our cool basement and it was then put into the back bedroom with a very warm floor and very cool air. Poor little guys. Lol. I moved them all out to the unheated garage last week and they have picked up now.
Sorry you have buggies that also developed on yours :( Hopefully the rest can be saved. If ever there was a year to have home grown tomatoes, this would definitely be at the top of the list.
Last year I used a mild spray of a bit of neem oil with a few drops of rosemary essential oil into just warmed water, and very lightly misted over my tomatoes. Worked against the aphids and they didnt come back the rest of the summer. Also worked on my squash and cucumbers against the beetles that showed up. Not sure about whitefly but good grief neem is truly vile smelling, so hey it might work.
If you do go the neem route, be stingy. Lol. It seriously stinks with this awful skunky musk. And it stays stuck to your skin so if you (accidentally) spray it onto your arms you'll have the advantage of mosquito repellant. But you'll smell just awful. Its a husband repellant too. Lol. Tried and tested.
