Bleach Treatment of Tomato Seeds

Food for thought when you don't know how the Tomato seeds you get, either given or purchased have been fermented and whether or not they carry any disease from their point of origin. In an experiment today, I bleach treated 3 lots of seed prior to sowing. Mixing an 8% solution of laundry bleach in water (4ml to 50ml) I then soaked the seeds for 10 minutes prior to rinsing well in a small sieve, then drained on a filter paper before sowing.

The recommended treatment is for 10% for 10 minutes, but as only 4 seeds were involved at a time I used the 8% which is still satisfactory.

To keep your seeds disease free, this is an option if seed comes from a source other than your own.
