Help ! I have read your information on thrip control. They showed up on my pink roses here in Ohio last summer and absolutely nothing killed them that I could buy locally. They ruined every pink rose I had last summer. I finally cut all the blooms off (just about killed me!!) to get rid of them….but alas of course they returned. I had these bugs when I lived in S Carolina, but never experienced them here in Ohio…until summer of 2011. The only thing I found that killed some of them was yellow sticky fly/bug strips….which just looked lovely next to my bushes.. 🙁 I hate using dangerous and expensive methods on my roses…..but I know they will show up with the first blooms of summer this year. I am printing out your info….but can you offer anymore. I live in NE Ohio. We are having a very mild…warmer than usual winter. Thank you for any more information.
I’m not sure what else we can offer information wise. Now we do have a product called PEST AWAY that is organic and won’t kill anything. And it will repel them. Did you see that offering? Here is a link
As for chemical options; PROTHOR is very safe AND used as a soil drench. This means the treatment can be done to the soil around affected plants and so there will be no direct hazard presented to the foliage or roses. For us, this is the best option by far.
But as the expression goes, you need to “choose your poison” because in the end, thrips are highly destructive if left to do as they please, will no doubt kill your roses if you don’t treat.
