104 AMERICAN CARNATION CULTURE. 



Dry Bordeaux is sprinkled over all paths and under all 

 benches every two months. 



Carnation plants should not be syringed if any trace of Rust 

 or Spot is about the premises. All diseased plants should be 

 promptly burned. 



By the above means we have not had a trace of rust on our 

 stock." 



FAIRY RINGS (Heterospotium Echinulatum.) 

 This is a trouble easily controlled by using a half-pound of 

 carbolic acid diluted, and used as a spray. > 



FUNGUS IN THE CUTTING BENCH. 

 This variety of Fungus is believed to be identical with the 

 one causing wet stem rot (Rhizoctonia) , the conditions being 

 similar for its development in both instances, a close atmosphere, 

 moisture, heat and decaying vegetable elements in the bench-sand 

 is the cause of Rhizoctonia in the cutting bench. 



REMEDY. 



Use sand, free from all impurities, renew it once a year, 

 white- wash the bottom and sides of the bench with fresh slacked 

 lime before it is filled with sand, and there will be no trouble 

 from this fungus. 



WET STEM ROT (Rhizoctonia.') 



This disease affects carnations in the field and on the benches, 

 and sometimes is very destructive. It is characterized by a moist 

 condition of the skin on the stem of the plant. If it is twisted, the 

 bark or skin will be found dead and disconnected with the sub- 

 tissue. It is most likely to occur on plants of a soft growth, in 

 hot weather, deficient light, wet spongy soil, that contains much 

 decaying organic matter, poor drainage and imperfect circulation 

 of air. Prof. Woods says it is caused by a fungus that may be de- 

 tected by the unassisted eye, and is favored by acid soils, excess 

 of heat, moisture and manure. Lime will reduce its frequency.
