Just after the blos- 

 soms fall and stamens 

 wither.

Ten days to 2 weeks 

 after the previous 

 spraying. 



First week in 

 August. 



What to Use and What For. 



Strong lime-sulphur wash, if San Jose scale is 

 present. This scale must be destroyed or it will ruin 

 the trees. 



For scurfy-scale* use lime-sulphur wash as late 

 as possible before buds swell. • 



Bordeaux mixture or dilute lime-sulphur solution 

 for scab, leaf-spot diseases and canker, with poison 

 for canker-worm and bud-moth. 



The experience of some growers indicates that this 

 spraying may be omitted if one has been made with 

 lime-sulphur for San Jose scale, unless canker-worm 

 is present. 



Bordeaux mixture or dilute lime-sulphur solution 

 for the diseases mentioned before with a poison for 

 bud-moth, tussock-moth, codling-moth and other in- 

 sects. 



This and the last are the most important single 

 sprayings. Do not neglect them. 



Same mixture for diseases and insects mentioned 

 above. 



Bordeaux mixture, not full strength, or dilute linie- 

 sulphur solution, and poison, full strength, for the 

 second generation of codling-moths, except on sum- 

 mer varieties. 



This is an important spraying, especially for late 

 fall and winter varieties. 



See "When the Coddling-Moth Flies" on later page. 



The lesser apple-worm, when present, requires a 

 spray of poison when standard winter varieties are 

 from 1 to li/o inches in diameter. 



A diluted solution of the boiled lime-sulphur wash 

 has come into considerable use during the past few 

 years as a substitute for the bordeaux mixture for 

 spraying apples. See later page. 



Too early.

Just right.
