Help! Thrips? Bud drop

crittermomJune 20, 2012

Hi daylily addicts! I have just started to have my daylilies bloom and have been waiting for this all year! My daylilies are loaded with scapes, and all of the sudden at least half of my plants are having bud drop! I'm heartbroken, and was near tears this morning when I was walking around the yard looking at it. I've never had this issue before. I'm thinking that maybe I have thrips that have taken over the garden. I've seen some REALLY tiny white bugs on them. They don't seem to be whiteflies, and are not aphids. Do you think that is what is causing the bud drop? Here are some pics of the scapes. If not thrips, any other ideas? I sprayed the scapes today with an insecticide, which I hate doing becuase I don't want to hurt the beneficial insects, but I just want at least a few flowers this year!

Bumps on the buds and mishapen buds usually indicate thrips. I don't know what your white bugs are. Thrips are very tiny, black, and look like the top part of an exclamation mark. I have them really bad this year. I recommend using Bayer's All In One systemic - the liquid kind you poor on the soil - and spraying your buds every few days with Spinosad. I bought Spinosad online at Amazon. Hope this helps. I know how heartbreaking this can be.

Or you can use a systemic and spray the folliage and the buds wuth bonide systemic insect control. Repeat in two weeks.

I feel your pain, Crittermom! Same problem here. Lots and lots of plants have dried out buds. And it happens so quickly, one day a scape, next day I look - they all dried out. I noticed another one today with all (!) scapes yellow.
Our theory is the weird weather, and lack of rain.
There are some buds with thrips damage too, I mean those bumps, so I am not entirely sure.

I've had several plants with those dried out buds this year, more than I ever have. Of course, 2 were on new plants. I've been blaming the dry, odd weather pattern. Oddly, I haven't had any problem with thrips this year. We had weeks of warm weather & then a hard frost, I wonder if that took care of them here.
