METHODS OF CONTROLLING, 
BURNING. 
One of the first methods suggested by writers for checking the 
spread of asparagus rust was burning the affected brush. In 
fact this has been the principal method recommended by Euro- 
pean writers such as Zimmerman,’, Frank® and Abbey’. At first 
Dr. Halsted® recommended the same treatment. Drs. Sturgis® 
and Stone” followed Dr. Halsted’s advice as did also Messis. 
Jones and Orton.” Ina later published work” Dr. Halsted says: 
“At best, with these precautions, many of the spores will get 
scattered upon the soil.” Mr, Kinney*y of Rhode Island, ques- 
tioned the advisability of burning the brush in late summer; 
and Jater Messrs. Stone and Smith"! took a similar view of burn- 
ing, stating that they had only recommended burning the in- 
fected plants late in the fall when they were thoroughly dead 
and dried out; and that they had never seen the slightest benefit 
from burning the infected tops, while cases had been brought 
to their attention in which actual injury had resulted from cut- 
ting the tops and burning them in August. Following all the 
above suggestions Dr. Pammel" in a recent bulletin recommends 
burning as undoubtedly the best method of preventing the rust. 
There is no doubt that in some sections the above measure has 
been abused. A few agricultural papers have recommended cut- 
ting and burning the beds,as soon as the rust is observed. As 
a result some growers have followed the latter method with more 
harm than benefit to their crops. In 1899 this was tested on two
