conidia of the fungus, while the more common symptom shown in the other two bulbs 
consists of the large sclerotia without sporulation. Samples taken from the untreated portion 
of Lot III (see Table V and the text) . . .. .. , 
O—Typical bulbs from the treated portion of Lot III. The disease was apparent at the time of
