a good mechanical mixture of the sulphur and the lime, only a small 

 percentage of the former going into solution. As soon as the lime 

 is thoroughly slaked more water should be added to stop further 

 chemical action, as there is some danger of dissolving enough sul- 

 phur to injure peach foliage. The mixture is then ready to be 

 strained and diluted for spraying. 



Outline of Treatment. — For the treatment of peach brown- 

 rot and scab, in Pennsylvania and adjacent territory, the following 

 is recommended : Spray the earlv A^arieties. like Carman. Hiley, 

 and Champion, about a month after the petals fall, and a month or 

 six weeks before the fruit ripens. Later varieties, as the Elberta, 

 Smock. Salway, and Bilyeu. will usually require three applications 

 for the best results : the first to be made a month after the petals 

 fall, the second three to four weeks later, and the third a month 

 to six weeks before the fruit ripens. 



For the curculio. arsenate of lead at the rate of two pounds to 

 each fiftv gallons of self-boiled lime-sulphur should be used in the 

 first application but not in the others. AMiere this insect is a seri- 

 ous factor, an application of arsenate of lead, two pounds to fifty 

 gallons of water with two or three pounds of lime, to be made a 

 few days after the petals fall, is recommended, but is probably not 

 often necessary in this section. ■ 



Mr. Nev/comer. Flave you found 2 lbs. of arsenate of lead 

 to control curculio on the peach? 



Ans. A great deal of work along this line has been done, and 

 as Mr. Scott recommends 2 lbs. I infer that it is the strength which 

 he has found sufficient. 



W. S. Adams. How Long will self-boiled lime-sulphur 

 keep ? 



Ans. It will keep quite a long time. I do not know that the 

 limit has been determined but it is several weeks, at least. It has 

 been used several weeks after it was prepared and it was appar- 

 ently in good condition. It should be kept in a closed vessel, on 

 account of evaporation. At the strength referred to it Avill stand 

 without crvstalizing. 



W. H. Black. Has the use of lime-sulphur been extended to 

 potatoes ? 



Ans. Xot to my knowledge. There is not the necessity for 

 that as in the case of fruit trees. Bordeaux is eft'ective in treating 

 potato diseases and causes no injury.
