This paper deals whith results of some observations on the Fusarium disease of Tulip and its pathogen which is ocoured the Jinzai Farm of Shimane Agricaltural College.
The fungus is only capable to infect the wounded suscept.
The lethal temperature for the pathogen is too high for the hot wather treatment of the bulb might be not suitable for means of disease control.
The conidia did not germinate at all in distilled weter but germinated in water drops which were formed on tulip leaf, in tulip leaf decoction and in pressed juice of tulip leaf respectivery.
Investigations on the varietal difference of the resistans of tulip bulbs to the in-vasion of pathogen were carricd out. Varieties 〟The Saltan〝 and 〟William Pit" were more resistant than 〟Feu Brilliant〝 and 〟Kansas〝. The results of the present obserbations on these tulip bulbs coincided with those facts which were found in the field.
Soaking of bulbs into some agicultural chemicals, especially Usplun, for 24 hours, have rot-reducing effect of the tulip bulbs.
Dusting of slaked lime on field after picking out of tulip flowers is also effective.
