(1) It is often recommended that the soil medium in which seeds are germinated should first be sterilized; to do this, soil can baked in the oven. To kill the damping-off fungi, the soil must reach 130 degrees F for 30 minutes. Most viruses will be dead after 30 minutes at 160F. It is not, however, necessary to sterilize soil unless previous problems have occurred because, in addition to killing disease organisms, it also destroys beneficials, which contribute to soil health. (2) Before pruning plants, especially those that may harbor disease, be sure to sterilize tools with a diluted ammonia solution (see pruning entry for more information).
