GENERAL TREATMENT FOR PEACHES.* 



When to Spray. 



Early in the spring, 

 surely before the buds 

 swell. 



What to Use and What For. 



Strong lime-sulphur wash for San Jose scale, it 

 present. This spraying will also answer for the leaf- 

 curl. If San Jose scale is not present, bordeaux mix- 

 ture for the leaf curl. 



FOR ORCHARDS AFFECTED WITH THE BROWN ROT;, SCAB^ AND CURCULIO. 



When to Spray. 

 1st time. 



What to Use and What For. 



About the time the shucks are shedding, spray 

 with arsenate of lead at rate of 2 pounds to 50 gal- 

 lons of water. 



2nd time. 



3rd time. 



Two to three weeks later or about one month after 

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

 sulphur and 2 pounds arsenate of lead. 



About one month before the fruit ripens, repeat 

 the above spraying, omitting the poison. 



For early varieties the first two sprayings will 

 probably be sufficient, unless the season is very wet 

 and the varieties very susceptible to rot. 



*Thi3 line of treatment and the preparation of tne 

 self-boiled lime-sulphur mixture are based upon the 

 recent successful experiments of the Bureau of 

 Plant Industry of the Department of Agriculture.
