Started to use peracetic acid to disinfect seeds for grafting. Soak times were 15 and 30 minutes. Peracetic acid concentrations were 0, 5600, 15000, 30000 and 50000 ppm. The goal of the first test is to see how high concentrations can go without affecting germination. The two lowest concentrations are proven to be 100% effective at complete disinfection without harm. I now am sure that the all the seeds that I will be using are clean, perfectly clean. The more I find out about this product, the more I like it. For example, you can reduce it to 1500 ppm and use it to disinfect soil...yes, like garden soil. Within 15 minutes there is no detectable product left and it is so remarkably effective at killing bacteria, fungus, and viruses. There is very little testing of the product on open field soil but it is very commonly used to sterilize soil mixes before the inoculation of beneficials. Not something you would want to pay to do to 1000 acres but 1000 square feet, now that is a different story. It could ease the pressures of not rotating crops.
