BULB NEMATODE CONTROL IN IRIS BY HOT WATER

Abstract
The immersion of iris bulbs in water at 110 to 112° F. for 60 min. effectively destroys the bulb nematode.The safe period for nematode destruction in iris by hot water lies between July 26 and August 9. Thereafter injury to the bulbs occurs and is progressively greater as the immersion dates are delayed.
