I40 THE AMERICAN PEACH ORCHARD 



boiled lime-sulphur offer the most satisfactory 

 means of fighting this disease. This spray has been 

 extensively investigated by Scott and Quaintance 

 who find that the fruit rot, the scab and the curculio 

 may all be fought with the same series of sprayings. 

 Their very interesting conclusions with regard to 

 the treatment of these troubles may be quoted in 

 full. They say : 



"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 prevalent. In some of the 

 more northern orchards the curculio is not very 

 troublesome, but as a rule it will probably pay to 

 add the arsenate oi lead in at least the first lime- 

 sulphur application." 



"The self-boiled lime-sulphur mixture referred to 

 in the following outlines of treatment should be 

 made of a strength of eight pounds of lime and eight 

 pounds of sulphur to each 50 gallons of water, and 

 the arsenate of lead should be used at the rate of 

 two 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 

 two to three pounds of good stone lime. When used 

 in the lime-sulphur mixture additional lime will not 

 be necessary." 



^' Mid season varieties — The midseason varieties of 

 peaches, such as Reeves, Belle, Early Crawford, El- 

 berta, Late Crawford, Chairs, Fox and Beers Smock 

 should be sprayed as follows: (i) With arsenate of 

 lead alone, about 10 days after the petals fall, or at 

 the time the calyxes are shedding, (2) with self- 

 boiled lime-sulphur and arsenate of lead, two weeks 

 later, or four to five weeks after the petals have been
