drained, rather thin lauds but on such soils will be greatly 

 benefited by moderate applications of the phosphates and 

 potash. 



The advisability of spraying with fungicides to combat 

 peach and plum rot is perhaps still au open question. 8ome 

 experimenters, particularly Professor Chester of the Dela- 

 ware Experiment Station, report very encouraging results, 

 but the foliage especially of the peach, is very liable to in- 

 jury from such applications and they must be made with 

 great care. The disease is so important that extensive experi- 

 ments are justified in attempting to control it, but only the 

 best pumps and Vermorel nozzles giving a fine inist-like 

 spray shoul i be used in making the applications. Professor 

 Chester * recommends the following treatment :— 



1st. During (he winter gather and burn all mummied 

 fruit. 



2nd. In winter or early spring (before the buds start) 

 spray with a solution of copper sulphate using one pound 

 to 25 gallons of water. 



3rd. When fruit buds begin to swell spray with Bordeaux 

 mixture made with six pound* of copper sidphate and at 

 least six pounds of quii-k lime to the barrel. 



4th. Spray again with Bordeaux mixture just before 

 the blossoms open. 



5th. As soon as the blossoms fall, spray again with the 

 Bordeaux mixture, to which is added three f)unces of Paris 

 green per barrel. This is on account of the curculio 

 which attacks the young fruit. The Paris green should be 

 rublied to a smooth paste with a little water before adding 

 to secure an even mixture. 



6th. In ten days repeat the Bordeaux and Paris green 



7th. When fruit begins to color, spray with copper 

 acetate (four ounces to the barrel of water). This is rec- 

 ommended instead of the Bordeaux at this stage, since it 

 does uoi adhere to the fruit nor disfigure it, and it is found 

 to be equally effective.
