This treatment is especially for tlie Curculio, wliicli makes the worm 

 at the pit, and it also prevents leaf-curl, rot, and other troubles to con- 

 siderable extent. 



This treatment should be given about a week after the bloom has 

 fallen from the trees — -at the time when the growing young peaches are 

 splitting off the dried-uj) shuck of the bloom, when about half of the 

 young peach shows free from the shuck. There is chance for the grower 

 to make nice discrimination and exercise judgment in deciding the exact 

 time for this application, and "a week after petals fall" is as good as we 

 can do in general statement of the time. 



3. Two or Three Weeks Later. — Use same as in previous treatment. 



4. About a Month Before Due to Ripen. — Same as the previous treat- 

 ment, but use no arsenate of lead. 



This last treatment is needed only for Elberta and other later varie- 

 ties. The varieties which ripen earlier than Elberta will usually be well 

 protected by the three treatments before mentioned. 



If arsenate of lead be used in this latest treatment, it will, from our 

 experience, give better color to the fruit, but it is not necessary so far as 

 Curculio is concerned. 



SPRAYING PEACHES AND PLUMS REDUCED TO SIMPLICITY. 



If the grower would rather adopt merely one material for use on his 

 peach and plum trees, even though the results be not always perfect, he 

 will find that the best one material to use will be the self-hailed Lime- 

 sulphur Wash (8 pounds lime, 8 pounds sulphur, 50 gallons water) and 

 3 pounds Arsenate of Lead. (See page 36.) The arsenate of lead need 

 be added only for treatments when there is fruit or foliage on the trees. 



This material if used three or four times during the season at the times 

 already mentioned will give quite good protection against most of the in- 

 sects and diseases Avliich can be controlled by spraying. 



The commercial lime-sulphur at 1 gallon to 60 gallons water and 2 

 pounds arsenate of lead might give fair results, but on this we are not 

 certain. Present experience favors the self-boiled lime-sulphur. 



HOW TO PREPARE THE MIXTURES. 



The work of preparing spraying mixtures has been greatly simplified 

 by the commercial sprays and washes now on the market, which are as 

 good or sometimes better than Avhat the grower can prepare for himself. 

 On page 40 Avill be found a list of firms that deal in spraying mixtures. 



COMMERCIAL LIME-SULPHUR WASH, 



The commercial lime-sulphur w^ashes can be bought ready-made from 

 the manufacturers or their agents in larger towns. Most of them are of 

 about the same strength, and can be reduced to proper strength for spray- 

 ing merely by adding water.
