tion may not be necessary. However, two- treatments will 

 usually be required, especially on late maturing varieties. 



Brown Rot and Scab Treatment. In orchards where 

 both brown-rot and scab are to be. combated, „the following is 

 the course of ■ treatment required: 



Spray with 8-8-50 self-boiled lime-sulphur (1) three to 

 four weeks after the petals fall (2) about three weeks later, 

 and (3) about one month before the fruit is expected to 

 ripen. This applies especially to the Elberta, Belle and other 

 mid-season varieties. The season being shorter, with earlier 

 maturing varieties, such as Waddell and Carman, only two 

 applications, the first and the third of the above outline, will 

 be required. 



Combined Scab, Brown-rat and Curculio Treatment. 

 Where the curculio occurs in injurious numbers it is neces- 

 sary to control it in order to obtain the best results from the 

 brown-rot treatment. Arsenate of lead should be used for 

 the purpose and the treatment .would then be as follows: 



I.-- About the time the calyces are shedding, shortly af- 

 ter, the petals drop, spray with arsenate of lead at the rate of 

 2 lbs. to 50 gallons of water. 



2. Two to three weeks later, or about one month after 

 the petals drop, spray with 8-8-50 self-boiled lime-sulphur and 

 2 lbs. -of arsenate of lead. 



3. About one month before the fruit: ripens spray with 

 8-8-50 self-boiled lime-sulphur,, omitting the poison. 



Preparation for Self-Boiled Lime-Sulphur. 



The mixture 'used in our experiments during the past 

 aeason was composed of 8 lbs. of fresh stone lime and 8 lbs. 

 of sulphur (either flowers or- flour may be used) to 50 gals, 

 of water. ■ This appears to be about the correct strength, al- 

 though in mild cases of scab and brown-rot a weaker mixture, 

 .containing 6 lbs. of each ingredient to 50 gals, of water, may 

 be used with satisfactory results. The mixture can best be 

 prepared in rather large quantities — say enough for 200 gals.
