when the scale is first discovered might be treated in the fall after the 

 leaves are off and again in late winter. But once the scale is subdued, 

 one treatment each winter is sufficient.

 before the buds open. It is fatal, or at least injurious, to young foliage, 

 blossoms, etc. If one is unavoidably delayed in using it and finds that 

 he must treat the trees after the buds have opened, the application should

 When this care is used, it may be used as a remedy for San Jose Scale 

 even in summer. 



When trees have been sprayed with the Lime-sulphur Wash in late 

 winter there is then no need to spray with the Bordeaux Mixture until 

 after the blossoms fall — in other words, a late- winter application of the 

 Lime-sulphur Wash takes the place of the late-winter application of 

 Bordeaux Mixture. The writer strongly advises that fruit growers 

 should use this remedy every two or three years anyway (even if no San 

 Jose Scale is known to be present) on account of its excellent general
