I have had some periodic bud drop and streaked flowers and it looks like thrips are the culprit. So last year, I tried a Bayer product, called Rose & Garden Care. It was a granular formula and systemic. So I put it around the base of my daylilies in the two gardens that I had issues in the past. I applied it the 3rd week of May and it was supposed to be good for 6 weeks. For once, my Final Touch had pretty flowers and I didn't see any other evidence.
So this year, I was looking for the granular form and came across the liquid concentrate. So I decided to try this. Today I did my first application. I kind of liked it better because I could target just the lower leaf and crown area. I do need to go back and see if it will last for 6 weeks or if I have to reapply sooner. I do like that since I could specifically target the plant, and I don't have any other flowers blooming in the area of the daylilies at this time, that there should be less harm to the bees.
