9 o THE BOOK OF THE LILY 



A fungus which is particularly destructive to imported 

 Japanese Lilies is known as Rhizopur necans. It is doubt- 

 less present in the soil before the bulbs leave Japan. 

 It first attacks the roots, and then passes into the bulb, 

 causing the base of the scales to decay. Care in lifting 

 and packing seems to be the only way to minimise the 

 effects of this disease. 



A good deal can be done to ward off most Lily ail- 

 ments by planting the bulbs under the most suitable 

 conditions, and treating them in such a way previous to 

 planting that they do not lose a great deal of their vitality 

 before they are placed in the ground. 



Insect pests as a rule give but little trouble, the prin- 

 cipal being Aphides or green fly, which is very injurious 

 to L. longiflorum under glass, and sometimes attacks them 

 out of doors. 



The insecticide known as the X. L. Vaporiser will 

 quickly destroy them in the greenhouse, and in the open 

 ground a little tobacco powder dusted into the crowns 

 (choosing for the operations a showery evening) will 

 soon clear them off, and other garden pests can be dealt 

 with in a way known to all attentive gardeners.
