OK, thanks. I'll do the alcohol treatment, as well as drench the soil with Bayer. I thought I treated my DRs with Bayer 3n1 before I brought them in last fall. But, I may not have, because thinking back, I was rushing to get plants in before an unexpected freeze. I also had a family emergency and had to go out of town at the same time. Would it do any good to stray the plants with Bayer?
