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 

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).
