fas present paper treats of important insect and 
fungous enemies of the grape in the United 
States, and gives for each the methods of control at 
present known to be most effective. There is also 
given at the close of the bulletin a schedule of appli- 
cations of combined insecticides and fungicides 
which, if carried out according to directions, will 
insure a high degree of protection from the various 
insect and fungous troubles of the grape. Com- 
mercial vineyardists, for the most part, follow some 
schedule of applications, though in many instances 
sufficient attention is not given to thoroughness or 
timeliness in treatments. 
In the case of grapes grown principally for home 
use, or on a small commercial scale, there is each 
year a large loss in the aggregate from failure of 
owners properly to spray their vines. The spray 
schedule should be especially useful to these indi- 
viduals, and if carefully followed will materially 
increase the quantity of fruit obtained. 
Vineyards, however, should not be sprayed so near 
ripening time of fruit that there will be left on the 
berries at harvest a noticeable amount of spray 
residue. Thorough applications early in the season 
as indicated in the schedule of treatment (p. 74) 
will obviate the necessity of later treatments with 
consequent discoloration of the fruit with the spray 
mixture.
