In 1869, the Massachusetts Horticultural Society offered a prize 

 of twenty-five dollars for "a safe, certain and economical method, 

 better than any now known, of destroying the currant worm, or 

 preventing its ravages." 



The most effective treatment is spraying with arsenate of lead at 

 the rate of about two ounces to three gallons of water (two pounds 

 to fifty gallons). One-fourth the amount of paris green may be 

 used instead if necessary. This spraying should be done early, 

 while the worms are still on the lower leaves. If neglected until 

 the fruit has developed so as to make arsenites unsafe, hellebore 

 at the rate of about a tablespoonful, an ounce or more, to the gallon 

 of water, must be substituted. This may also be used dry, at the 

 rate of one pound to five pounds of air-slaked lime. 



Allowing the bushes to be defoliated, even after the fruit is off, 

 injures the crop of the following year.
