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).
