After the blossom buds are formed, or in the spraying just as the 

 blossom buds open and those thereafter, it has been found most pro- 

 fitable to use two leads of hose behind the spray-machine and apply the 

 spray directly to the bunches by hand. This is an added expense, but 

 as above stated, it has proven profitable. 



There is some difference of opinion as to the proper time to spray 

 for the most efficient control at the least cost. Many advocate a dormant 

 spray and two other sprayings before the blossoms open, while others 

 contend that such early sprayings are unnecessary. The time for the 

 dormant spray is past, but a spray applied at any time before the 

 blossoms open can do no harm and will, no doubt, prove of value. The 

 most important sprayings are those applied just as the earliest blossoms 

 open and the next after the blossoms have fallen. Following these, two 

 more sprayings at two or three weeks' intervals should be made to pro- 

 tect the growing berries. Possibly a fifth spray should be applied, de- 

 pending somewhat on the season. As Bordeaux mixture discolors the 

 fruit, this should be the ammonia and copper-carbonate solution which 

 will leave no color on the fruit. 



Directions for mixing these sprays will be found in Iowa Bulletin 

 No. 89, which can be secured by writing the Director of the Agricultural 

 Experiment Station, Ames, Iowa. [National Horticulturist]
