sulphate, 2 pounds to 50 gallons of water for peach 

 leaf curl. Any of these will be effective if properly 

 applied. Spray from both directions to coat every 

 Luil, being sure to apply before buds have begun to

(b) Lime-sulphur, 32° Beaume, 1-8, for San Jose scale. 

 This will also control peach leaf curl.

(a) 'Scott's self-boiled lime-sulphur, 8-8-50, with arsenate of

 (b) Arsenate of lead, 2 pounds to 50 gallons of water, for 

 curculio. If the self -boiled lime-sulphur is omitted.
