164 BULBS AND THEIR CULTIVATION, 



EBMBDIES. Diseased plants should be burnt. To safe- 

 guard healthy plants from attack, spray with a solution 

 of Condy's Fluid. 



Freesia Disease. A relative of the Carnation Fairy 

 Ring fungus, named Heterosporium gracile, attacks the 

 leaves of freesias, irises, antholyzas, and hemerocallis, 

 forming oval pale brown spots, which eventually become 

 covered with an olive-brown mould. This disease speedily 

 kills the leaves if allowed to develop to any extent. 



REMEDIES. To prevent attack, or to check a slight 

 attack, spray the foliage with the following solution: Mix 

 together one ounce of carbonate of copper and five ounces 

 of carbonate of ammonia. Dissolve in a quart of hot 

 water, and make up to sixteen gallons with cold water. 

 Burn badly infested leaves and bulbs. 



Iris Bulb ScabThis fungoid disease forms black 

 patches on the surface of bulbs of I. reticulata, and gradu- 

 ally kills the bulbs. 



REMEDIES. Mr. George Masse recommends the bulbs 

 to be soaked for two hours in a solution of one part of 

 formalin to three hundred parts of water. This will cure 

 a slight infection ; badly attacked ones should be burnt. 



Tulip Mould. The stems, leaves, and flowers of 

 tulips are" occasionally attacked by a fungus called Sclero- 

 tinia parasitica, which causes olive-brown velvety patches 

 of mould to form thereon. It eventually descends to the 

 bulb, on which it forms a blackish crust, the bulb in due 

 course shrivelling and decaying. 



REMEDIES. Directly the mould is observed on the foliage 

 pull the bulb up and burn it. 



Snowdrop Mildew. _ A fungoid disease which 

 attacks the bulbs of the snowdrops, and gradually spreads
