be inevitably some loss from dripping. It can hardly be 

 otherwise, but ideal spraying permits of only a minimum of 

 dripping. Timeliness is of no less importance than thorough- 

 ness. The proper preparation applied thoroughly and at 

 the right time gives success in spraying. With fault in any 

 of these particulars the result will be failure in proportion 

 to the degree of the fault. 



Perhaps the most satisfactory spraying program appli- 

 cable generally throughout peach-growing regions for the 

 principal insects and diseases that require treatment during 

 the period of active tree growth is the one offered by Scott 

 and Quaintance/ which is as follows : 



Schedule of applications. 



'' Most of the peach orchards in the eastern half of the 

 United States should be given the combined treatment for 

 brown-rot, scab, and curculio. This is particularly true 

 of the southern orchards, where all these troubles are prev- 

 alent. In some of the more northern orchards the cur- 

 culio is not very troublesome, but as a rule it will probably 

 pay to add the arsenate of lead in at least the first lime- 

 sulfur application. 



"The self-boiled lime-sulfur mixture referred to in the 

 following outlines of treatment should be made of a strength 

 of 8 pounds of lime and 8 pounds of sulfur to each 50 gallons 

 of water, and the arsenate of lead should be used at the rate 

 of 2 pounds to each 50 gallons of the mixture or of water. 

 When the poison is used in water, there should be added 

 the milk of lime made from slaking 2 to 3 pounds of good 

 stone lime. When used in the lime-sulfur mixture addi- 

 tional lime will not be necessary.
