Thiram is a fungicide which is used to treat pepper seeds and other cultivars. It is used to keep the seeds from rotting before they germinate. Quite a few of the seeds which I sell and of course grow are treated with Thiram, and Chlorine (Georgia Treatment). Stokes Seeds, a Canadian firm which also has offices in the US has most of their seeds treated with Thiram. A French company (Semintech) which I purchase seeds from treats with Thiram and Maliathon, an insecticide. Remember that treatments only affect the seed cover, which drops off along with the seed leaves after germination and is never in contact with plant tissue or fruit. My only precaution would be to wash your hands after handling the seeds.
