Something has invaded my greenhouse and is crippling flowers. Not all flowers are affected but at least half. Some older flowers seem ok but new and buds are being destroyed! See photos.

What to do???

Were they sprayed with something?

Yes, Cleary's 3336 - but only after the damage started.

I have had thrips produce damage like this. A Bayer systemic product containing Imidacloprid took care of it but it took several applications.

Thanks for the suggestion. I was wondering if it was a pest rather than a disease. Being of the age where seeing tiny things is harder, I have so far failed to detect any little critters. But I'll definitely spray. Kind of at my wit's end here.

Yes, I agreed with Kip. Could be thrips damage.

Thanks Peter and Kip. I found some thrips today and sprayed with imidacloprid. I'll do that three times and switch to Orthene.

I've been growing orchids in the Pacific Northwest nearly 40 years and never had thrips before. Always a new challenge to growing orchids!

Thanks again, David

David, could be floral mites. If it is, imidachloprid won't help as it only affects insects, not arachnids. I use Tetrasan for mites. While Talstar works for some mites, I haven't had any results using it on floral mites. Floral mites are very, very small.

Thanks Randy. I examined a bud that I found on the floor yesterday and confirmed a thrip inside. Small, slender and black. I ordered something called Conserve that seems to be highly regarded against this pest. Think I'll just cut all my flowers off and start an aggressive rotation of spraying.

I guess this is what happens when you get so busy you neglect the greenhouse.
