 fore the flowers expand, with bordeaux mixture.

FOR CURL LEAP ON THE PEACH. 



Prof. Newton B. Pierce says: "Curl leaf on the peach is caused 

 by a parasitic fungus which is known as Taplirina deformans. The 

 fungus lives within the tissues of the leaf, in the tender shoots, and 

 in the buds. Within the past few months I have learned that lime, 

 sulphur, and salt is a satisfactory preventive of this widespread 

 disease. The application of this spray should be made three to 

 five weeks before the buds open in the spring. The treatment should 

 be very thorough ; or spray with bordeaux mixture six weeks, and 

 again three weeks later, before the buds begin to swell."
