WET STEM HOT. 105 



The Geneva experimental station has discovered it on thirty 

 species of cultivated plants. It causes leaf rot in lettuce and is 

 the fungus of the cutting bench. It is propagated through the 

 soil and not the air. 



REMEDY. 



Reverse abnormal conditions with cultural methods. L,ime 

 as a remedy is indicated by Mr. Scott, who is an extensive carna- 

 tion grower, in a soil strongly impregnated with lime, and reports 

 substantially no stem rot. Mr. May, an observing cultivator of 

 carnations, says he lost seventy- five per cent of his plants with 

 stem rot, but after giving his soil fifty bushels of lime to the acre, 

 has grown carnations on the same land without any stem rot 

 trouble. This fungus spreads slowly through the soil, but never 

 through the air. It luxuriates in moist decaying vegetable matter 

 and attacks the stems and roots of carnations and other plants. 



SPOT DISEASE (Septoria Dianthi.) 



This disease was first noticed in 1889. It is recognized by 

 roundish spots on the leaves and stems of the plant, has a pale 

 yellowish color on the margin of the healthy tissue around 

 which is a tinge of purple or red. The spots are easily dis- 

 tinguished from either side of the leaf, there are numerous black 

 dots scattered over the pale area, which gives the name to the 

 disease. 



REMEDY. 



Make a strong tea of Coculus Indicus, also a tea equally as 

 strong of Quassa, a half-pound of carbolic acid. To each half pint 

 of above add ten grains of corrosive sublimate. Use one table- 

 spoonful to one gallon of water, as a spray. 



DRY STEM ROT (Fztsatium.) 



This is another disease of the stem of the carnation plant, 

 but not so general as the other. It is caused by a fungus that de- 

 velops in the capilliary vessels of the stem, causing it to become 

 dead, dry, hard and stringy. Prof. Woods says this fungus 

 thrives in a reverse condition of the soil favorable for the "Wet
