So I was lazy--yes, I have H2O2, but I had my 1:4 alcohol:water solution (that I use to kill the aphids on my overwintering roses) already mixed up. I sprayed the seeds with that as they lay on top of the dirt. The yellow dots disappeared instantly, has yet to return, and the lantana seeds sprouted a couple days ago.
Would the yellow dots have hurt my seeds? Don't know. Were they already going to sprout anyway? Don't know. But getting rid of the yellow dots did give me peace of mind, and the alcohol did do it!
