Fig. 6 killed by the poison. This remedy is worthy of trial if the cherry fruit fly should becomea very serious pest. Early spring flowing will no doubt burymany of the pupas and prevent the flies from emerging. Allfruit that falls or that remains on the trees after harvestshould be destroyed.

The remedy is to cut out and bum the affectedbranches as soon as they are discovered. Fig. 7 shows cherrybranches affected with black knot. 31. Brown rot is the most serious fungous disease withwhich cherry growers have to contend, and some varieties ofsweet cherries are especially subject to its attack. Fruit thatcracks is especially liable to be attacked. Hot, moist atmos-pheric conditions, when occurring at the time the fruit is CHERRIES, APRICOTS, AND QUINCES § 20 ripening, are favorable to the spread of this disease. Bordeauxmixture has been used with partial success to control thefungus, but the foliage of the sweet cherry is very susceptibleto injury by Bordeaux. Some growers believe that self-boiledlime-sulphur will prove to be an excellent remedy for thedisease. Injury from this fungus may be lessene
