Spray with the lime-sulphur-salt wash as late in winter as 

 possible.

apricot. It makes its appearance upon the leaves, forming 

 reddish-brown spots, which, when mature, shrink from the 

 surrounding tissue and are blow^n away, leaving the leaf 

 perforated. When the fungus attacks the fruit, it first appears 

 as minute red pimples, which are very often mistaken for scale 

 insects. These soon develop and burst open at the top, the 

 new spores escaping and spreading the disease. The old spot 

 forms a scab, which spreads and joins others, and soon the 

 surface becomes very rough, rendering the fruit unsalable. 



Spray with the lime-sulphur-salt solution in winter, and use 

 the Bordeaux mixture (formula B) just when the buds are 

 swelling. If the lime-sulphur-salt remedy is not used, then 

 the Bordeaux mixture (formula A) should be applied as early 

 in the season as possible.
