make your own Lime-sulphur Wash at strength of 15 pounds lime, 15 

 pounds sulphur, 50 gallons water. (See page 29.) 



This treatment is for the San Jose Scale, which is very destructive in 

 many peach orchards of the State. If the scale is not present, then this 

 treatment can be omitted; but it has such a good general effect on the 

 tree that it ought to be used every two or three years anyway. If the 

 scale is present, it should be used every year. It helps against leafcurl 

 and rot. 



2. Just After Petals Fall, Promptly. -Use the self-boiled Lime-sul- 

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

 add 3 pounds of Arsenate of Lead. (See page 31.) 



Notice that here we recommend the self-boiled lime-sulphur, and not 

 the commercial material, and notice that 3 pounds of arsenate of lead is 

 used to the barrel (50 gallons). 



This treatment is especially for the Curculio, which makes the worm 

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

 siderable extent. 



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



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



treatment, 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 groAver 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 -boiled Lime- 

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

 3 pounds Arsenate of Lead. (See page 31.) 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 insects and diseases which can be controlled by spraying. 



The commercial lime-sulphur at 1 gallon to 50 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 what the grower can prepare for himself. 

 On page 34 will be found a list of firms that deal in spraying mixtures.
