I would say thrips since I have seen that same mottling and spraying for them resulted in getting blooms without it. Seems to be necessary these days in a lot of areas of the country.

Thanks, where would I buy the spray? What is it called? I appreciate the suggestion.

Looks like thrips to me. Floota said Bob Schwarz uses an organic spray and thinks the formula is 1/4 cup of Murphy's Oil Soap to 1 cup of water. I'll probably try that on the remaining buds this year, and then next spring I'll get downright mean and use Merit, as suggested by our daylily forum friend, Ed.

They've been really bad here in our new garden this year and they caught me by surprise. I've looked at blossom after blossom ruined by them. They really go after the ruffled daylilies, especially the reds and purples. I'm declaring war on thrips!

I'd be sure the formula is correct since I just did a google search and a post showed from Tinkers site where the formula was: Murphy Furniture Oil SOAP. 1 Tbs to 1 Gal of water.

Not saying which is correct since you can see that 1/4 cup Murphy's Oil Soap to 1 cup water is very different from 1 Tbs Murphy's Oil to 1 Gallon of water. So which one is correct?

Perhaps it would be better to contact Bob Schwarz first to be sure the correct measurement if thinking of using this formula.

Good luck.
