OOOPS... forgot this! I originally sprayed for the flea beetles with Schultz pyrethins spray, then next day I sprayed with the Safer 3in1, then the next day was the hot weather day.

I had the same thing happen to me last season. I used that stuff and then it got real hot in late May. It burnt my plants and I think it even distorted their future growth. I threw the stuff out and will not use it again but from what I recall there is a warning on the label not to use it when it is over 90 degrees outside. Time will tell. Your plants may very well grow out of the effects but I really don't think mine did. As I said I will not use it again.

Yes, it does say that on the label... sigh. I hesitated for a minute before applying it, because of the forecast, but since it was only in the low 80s that day, and I was desperate to get rid of the flea beetles I did it anyway. I think I will try to contact the manufacturer to see if they can give me any insight.
You say you think it distorted the growth of your plants. Could you describe what happened? Did you end up with any tomatoes at all?
As of today they don't look too bad, just a small portion of curled leaves on each, so I am thinking they will be okay. These are my first tomato plants started from seed, so they have to be okay!

My mistake was really spraying the growing tips heavy and they just cooked. If you are getting new growth you should be OK. The leaves on some of my plants got twisted and distorted and that continued all season. I still got tomatoes. I also called the manufacturer and was told the product could not have burned my plants. I really think they were too small when I sprayed them and it unfortunately got way too hot outside that afternoon. Real bad timing on my part. I still will not use the stuff again.
