Eel Worms. 



Rose groAver.s are sometimes troubled with eel worms, and 

 in some instances large losses have resulted (see Fig. 10). 

 In one instance, to our knowledge, a rose establishnuuit, 

 which had produced 

 $17,000 worth of 

 roses annually, re- 

 duced its out})ut for 

 a few years to about ^^ 

 $2,000 or $3,0 00, 

 due to the disastrous 

 results of eel worms. 

 Other instances could 

 be cited where rose 

 growers have been 

 almost forced out of 

 business by the pests. In some establishments, where un- 

 usual care' has been taken, the houses have never become 

 infested with these worms. For remedies, consult "Toma- 

 toes," etc. 



Caenations. 



Rust {Uromyces caryophijlh'nuK, (Schrank) Schrt.). 

 This fungous parasite, which is familiar to every one who 

 grows carnations, is not dreaded so much as when it first 

 made its ai)pearance some years ago. It is decidedly less 

 prevalent at the present time, by reason, perhaps, of less 

 susceptible varieties being grown, and also because carna- 

 tion growers have become more familiar with the conditions 

 which succeed in reducing the rust. The practice of sub- 

 irrigation and liming the foliage, together with attention to 

 moisture conditions, has been responsible for a diminishing 

 number of rusty plants. Spraying experiments have never 

 proven satisfactory for the carnation rust, and the best and 

 most rational remedies, here, as elsewhere, consist in pay- 

 injj attention to cultural conditions.
