For Bleep's Sake!

This morning I discovered thrips on Quietness. One of the three flower buds had dark splotches on it, and when I peeled back the petals I saw the tiny brown buggers. So I had no choice but to chop two of the three buds off. I haven't noticed any thrippiness on the last bud, but if I do that one will have to go as well.

I guess I shouldn't be surprised. Part of me wonders if I should remove the last bud as a precaution. After all, that shrub rose has only been in the ground for only six weeks, and should be winding down for its winter nap. I'll probably keep it on for a week before I decide what to do.

I gave all the rose bushes a dose of Actinovate in their surrounding soil. Those nematodes should build up in the soil and eat the thrip larvae...eventually. I'm spraying with insecticidal soap every couple of days. I know I shouldn't feel too discouraged, because my efforts to control the thrips have at least resulted in some success with Moondance. But really...how discouraging.

I'm not even thinking about a systemic treatment until I've exhausted all my options. Spraying a pesticide would not only kill the thrips, but also the beneficial insects that help eliminate thrips. I'm seriously considering getting some green lacewings for the garden next spring. I'd rather buy helpful insects and release them into the yard than use the pesticide. Other than the fact that it's unethical and destructive to use a chemical in your garden that kills bees...we need those pollinators for our raspberries. Talk about shooting yourself in the foot.

After all, I have witnessed the miracle of a serious black fly infestation on our mock orange being devoured by a small horde of ladybugs...

I wonder how many rosarians see thrips on their flowers and just ignore them? They say they're attracted to mostly light-colored roses, but there's truth in the supposition that they're just more noticeable on them. I've browsed the web and found a lot of photos of roses that have thrip damage. Since my first rose bush had white flowers, I couldn't help but notice them...
