RECOMMENDATIONS. 
The results of the post-harvest experiments conducted in Georgia 
in 1921 and 1922, which are substantiated by the results of similar 
experiments in Mississippi in 1919 and 1920, show that many adult 
curculios can be killed before they go into hibernation by applying 
arsenate of lead. Where the curculio infestation during the peach 
season has been severe, post-harvest applications of arsenate of lead 
are profitable, because of the protection given the next peach crop 
by reducing the number of beetles in the fall before they go into 
hibernation and while they are forced to feed on the peach foliage. 
Ten per cent arsenate of lead and 90 per cent hydrated lime dust 
should be used for this work, making the first treatment four weeks 
after the harvest of the last variety of peaches, followed by a second 
application two weeks later. The first application should not be 
made sooner than four weeks after harvest, as the curculio does con- 
siderable feeding for several weeks following the harvest on the peach 
fruits left in the orchard.
