within two weeks after the third. Possibly it may be delayed 

 until three weeks after the third, but this will depend on the 

 season and perhaps the section of the State. What to use: 

 Lime-sulfur and lead arsenate (summer strength) as given 

 under the heading "Combined Insecticides and Fungicides," 

 page 112. For: Codling moth, curculio, lesser apple worm and 

 any other chewing insects which may be present; scab, bitter- 

 rot, black-rot, sooty-mold and fly-speck, brown-rot, fruit-spot. 



The above schedule is recommended for all parts of the 

 State except the extreme eastern section. It is probable that 

 there should be some modifications of it for that region, but 

 a definite program cannot be offered until investigational 

 ^work has been done on which a new schedule may be based. 

 It is possible that a greater number and more frequent appli- 

 cations of fungicides may prove necessary for eastern Massa- 

 chusetts. 



On the other hand, certain of the applications in the schedule 

 might be omitted in some orchards without material reduction 

 of control. At present, experience and judgment must govern 

 one in determining whether this may safely be done. 



In a wet or cloudy siunmer season, where sooty-blotch and 

 fly-speck have been prevalent in previous years, an application 

 of lime-sulfur in August will be beneficial in checking this 

 disease. 



No apple grower can afford to omit the second and third 

 applications, — the so-called cluster-bud and calyx sprays.
