barrels, or 200 gallons, an acre at each application, making for the five 

 applications a total of 1,000 gallons to the acre. 



In undertaking the application of Bordeaux mixture it is necessary 

 that all material and apparatus be in perfect readiness before the time 

 to begin the work, and nothing should be allowed to interfere with the 

 application of the fungicide at proper intervals; otherwise, the results 

 will be unsatisfactory, and the remedy is likely to be unjustly con- 

 demned. 



The necessit}^ for care and thoroughness in the preparation and appli- 

 cation of the mixture must also be strongly emphasized. The mixture 

 should be made as described in Farmers' Bulletin No. 221, using only 

 good, fresh stone lime and adding resin-fishoil soap. A good nozzle 

 (the Vermorel type is best) should be used and the vines very thor- 

 oughly covered at each spraying. Four barrels of the mixture to the 

 acre are ordinarily sufficient, but where the vines are very dense and 

 heavy five barrels may be necessary. Where there is an excessive 

 growth of vines, it will be found advantageous to rake them with a 

 knife rake and thin them out, as is frequently done in order to prepare 

 a bog for picking with scoops.
