Hi All, I've been reading up on bulb cuttage lately, and these are a few of the points I've gleaned so far: Heat treating bulbs at ca. 50°C [ca. 122°F] is a general way to kill many bulb pathogens. A little too much heat, however, and you kill the bulbs too. Too little heat, and you don't kill the pathogens. Fungicides are of several types. There are surface-contact sporicides like Daconil, and there are systemic fungistats like thiophanate-methyl and many others. Surface sterilization with Clorox (5.25% sodium hypochlorite) diluted 1 to 20 in water is very effective; soak for about an hour. Less caustic sterilizing agents are the cationic detergents like Physan and Consan. It is a very good idea to sterilize your work space and your tools with at least a 10-minute soak in Physan 20 solution (1 tablespoon [15 mL] Physan 20 in 1 US gallon [3.785 L] of water).
