coming season “every precaution will be taken to apply it in advance 
of the fungus” 
This last statement is tbe key to success in the treatment of all fun¬ 
gous parasites. The treatments must be made before infection has 
taken place. 
BORDEAUX MIXTURE FOR THE PLUM LEAF-BLIGHT. 
In many parts of the South and West peach and plum trees suffer 
from the attacks of a parasitic fungus (Puccinia pruni-spinosa) belong¬ 
ing to the rust family. This fungus attacks the leaves, causing them to 
fall long before the proper season. During the summer and autumn of 
1888 Prof. T. L. Brunk, at our suggestion, conducted a series of experi¬ 
ments at the Texas Agricultural College with the view of finding a 
remedy for this pest. Professor Brunk writes as follows concerning the 
results of his experiments : 
I s».m greatly encouraged by our experiments with the Bordeaux mixture sprayed 
upon two rows of trees August 21 last. Two rows which alternated with three others 
that were carefully and thoroughly pruned last winter were selected for the spraying. 
On Octobers the plants were examined and it was found that those not treated had 
lost nearly all of their foliage, while those sprayed had lost only a very small per cent. 
Professor Brunk concludes as follows : 
At this writing (October 30) the difference in the treated and untreated trees is very 
marked. Those that were sprayed have yet about two-fifthsof their leaves, while the 
alternating check-rows are nearly leafiess. We intend to begin in the spring next 
year, and I believe that if the trees are syrayed about three times during the growing 
season—the first when the fruit is setting, the second about a month later, and the 
third in August, or after the fruit is picked—that the fungus will cause little injury. 
A TOMATO DISEASE. 
Of late years Mr. Marcius Wilson, of Vineland, N. J., has had consid¬ 
erable trouble with a fungus which attacks his tomatoes, especially those 
grown under glass. It appears on the leaves and young shoots at any 
time during the winter, and often kills them outright or greatly injures 
their vitality. From specimens communicated by Mr. Wilson it was 
learned that the disease was caused by Gladosporium fulvum , a fungus 
which has occasioned considerable injury in England. 
According to Col. A. W. Pearson, Mr. Wilson has succeeded this year 
in completely holding this fungus in check by the use of the Bordeaux 
mixture, containing G pounds of copper and 4 pounds of lime to 22 
gallons of water. The first application was made in December, while 
the plants were yet apparently healthy. For applying the remedy the 
Eureka Sprayer was used, and it answered the purpose “admirably.”
