its attacks. The second spraying should be made while the 

 leaves are unfolding, and thereafter the treatment should be 

 repeated at intervals of ten to fourteen days until there is 

 danger of permanently spotting the fruit. Upon the appearance 

 of worms add Paris green or green arsenoid to the mixture. In 

 wet seasons one or two applications should be made after the 

 fruit is gathered. ' 



Spraying in the early part of the season should be done with 

 especial thoroughness and regularity in order, if possible, to 

 keep the diseases completely under control until the time when 

 the spraying must be discontinued on account of spotting the 

 fruit. 



To restate the matter briefly: Spray thoroughly with Bor- 

 deaux mixture, commencing before the leaves appear. Make 

 the second treatment as the leaves are unfolding and thereafter 

 at intervals of ten to fourteen days until the fruit is two'-thirds 

 grown. In wet seasons make one or two applications after the 

 fruit is gathered. When worms appear add Paris green or green 

 arsenoid to the Bordeaux. 



It seems to us probable that currant growers in the Hudson 

 Valley will find spraying, as suggested above, a profitable prac- 

 tice. Anthracnose may not be epidemic except occasionally, but 

 it probably does some damage nearly every season. Leaf spot is 

 nearly always plentiful in the latter part of the sesiaon, and 

 sometimes causes the leaves to fall before the fruit is ripe. Cane 

 blight is always destructive, and one application must be made 

 for the worms anyway. We believe that loss from all these 

 troubles may be materially lessened by spraying. While the cur- 

 rant bears premature defoliation remarkably well, preservation 

 of the foliage must result in increased vigor of the plants and 

 consequently, larger yields of fruit.
