DISEASES OF TREE AND FRUIT I4I 



shed. (3) With self-boiled lime-sulphur alone, four 

 to five weeks before the fruit ripens." 



"Late varieties — The Salway, Heath, Bilyeu, and 

 varieties with similar ripening period should be 

 given the same treatment prescribed for midseason 

 varieties, with an additional treatment of self-boiled 

 lime-sulphur alone, to be applied three or four weeks 

 after the second application." 



"Early varieties — The Greensboro, Carman, Hiley, 

 Mountain Rose, and varieties having the same ripen- 

 ing period should receive the first and second appli- 

 cations prescribed for midseason varieties." 



"Where the curculio is not particularly bad, as in 

 Connecticut, western New York, and Michigan, the 

 first treatment, which is for this insect alone, may 

 be omitted. Also for numerous orchards through- 

 out the Middle States where the insect, especially in 

 the younger orchards, is not yet very troublesome, 

 orchardists should use their judgment as to whether 

 the first application may be safely omitted. Where 

 peach scab is the chief trouble, the brown-rot and 

 the curculio are of only minor importance, as may 

 be the case in some of the Allegheny Mountain dis- 

 tricts, satisfactory results may be had from two ap- 

 plications; namely, the first with self-boiled lime- 

 sulphur and arsenate of lead four to five weeks after 

 the petals fall, and the second treatment of the 

 above schedule with self-boiled lime-sulphur alone 

 three to four weeks later. These two treatments, if 

 thoroughly applied, will control the scab and the 

 brown-rot, especially of the early and midseason 

 varieties, and will materially reduce curculio inju- 

 ries. Even one application of the combined spray 

 made about five weeks after the petals fall would 

 pay well, although this is recommended only for 

 conditions where it is not feasible to do more."
