Any infectious agent associated with seeds that have the capacity to cause plant or seedling disease may be consid- ered as seed borne pathogen. This term comprised the plant pathogens such as bacteria, fungi, nematodes, and other mi- cro-organisms, and viruses, all of which can be carried in, or with the seeds
Ok this sounds like it could be something worth doing then I wondered what exactly and got this.
The seed-borne diseases such as leaf stripe, Fusarium, and loose smut are largely controlled by the use of certified seed and seed treatments. The mosaic viruses (barley yellow mosaic virus (BaYMV) and barley mild mosaic virus (BaMMV)) can be a problem where winter barley has been grown too frequently.
Those are internal and won't wash off so now I'm more confused.
