PEACH YELLOWS AND PEACH ROSETTE. 185 



(18) August 10, 1888. Variety, Reeves' Favorite. One small limb was removed; two 

 larger ones were left. The excised limb bore ripe and nearly ripe peaches on many 

 branches and bore no green fruit. There were some small, diseased shoots well out 

 upon one branc,hand a feeble shoot one fourth inch long had developed from an obscure 

 bud and pushed through the bark only one inch above the cut. This was not discovered 

 in time or the tree would have been rejected. The spring foliage was full grown, but 

 in places in began to look yellowish. The stump was sound. The remainder of the 

 tree was full of green peaches and healthy foliage. j 



May 13, 1889. Doubtful. A few feeble shoots are growing on the trunk below the 

 stub of the excised limb, and on the base of another limb. 



September 17, 1889. Symptons of yellows are now present. From the stub of the 

 excised limb have grown two much-branched, feeble shoots upon which winter buds 

 are now germinating. Such a shoot has grown also from the trunk, fourteen inches 

 below the cut. There is also a small, diseased shoot on the base of a main limb, twelve 

 inches above the excision. Otherwise the tree appears to be healthy. There was no 

 fruit this year. 



October 11, 1890. The foliage is abnormally reddish, and the winter buds are now 

 germinating upon two large shoots, which have grown from the base of the main limbs. 

 No fruit in 1890. 



(19) August 10, 1888. Variety, Reeves' Favorite. One limb was removed. Two small 

 branches bore ripe, red-spotted fruit. These branches joined the main limb about 

 eight feet above the cut. Six other branches of about the same size bore green peaches. 

 The entire limb bore full-grown, dark-green foliage; and there were no diseased shoots. 

 The stump was sound. The remaining limbs bore healthy, green peaches and excellent 

 foliage. 



May 13, 1889. There are a few sprouts of uncertain character on the stub of the 

 excised limb. Otherwise the tree appears to be healthy. 



September 17, 1889. The top bears good foliage and looks healthy, but several 

 branched and feeble diseased snoots have grown from the stub of the excised limb. 

 There is no fruit, and I can find no certain indications of disease on any other part of 

 the tree. 



October 11, 1890. For the time of year there is more than the usual amount of foliage 

 on this tree, and it is of better size and color, and less curled than on many of the trees. 

 However, several terminal buds have pushed in the top of the tree, and winter buds are 

 now germinating on six different shoots which have grown from the base of the main 

 limbs. One of these shoots pushed twenty-eight buds in late summer or early fall. 

 These made a spindling growth of two to four inches, and are now dead. On the same 

 shoot sixteen additional buds are now germinating. There was no fruit in 1890. 



(20) August 10, 1888. Variety, Oldm ixon. One limb was removed; three limbs were 

 left. The excised limb bore premature peaches on nearly every branch. One diseased 

 shoot, one eighth inch long, was pushing through the bark about two feet above the cut, 

 and a half dozen others, one eighth inch to one inch long, were visible higher up. There 

 were no others, and the spring foliage was healthy. The remaining limbs were full of 

 healthy foliage and green peaches, which Mr. Price said ought to ripen from nine to 

 twelve days later. 



May 13, 1889. Doubtful. There are some indications of disease near the stub of the 

 excised limb. 



September 17, 1889. The tree is now badly diseased. A half dozen rank-growing 

 branched yellows shoots have pushed from the trunk below the excision and from the 

 base of the limbs above it. Feeble yellows shoots are abundant on both main branches 

 of one limb all the way to the ends of the twigs in the top of the tree, i. e., twelve feet 

 above the excision. The spring foliage on this limb is also dwarfed, curled and yellowish. 

 On another limb the spring foliage is normal, but there is a diseased shoot at its base, 

 and another about three feet up. The third limb appears to be entirely healthy. No 

 fruit. 



October 11, 1890. The foliage is very red and unhealthy-looking, and sickly shoots 

 have grown not only in the top of the tree but also next to the roots and on the base of 

 the limbs; and winter buds are now germinating. The tree bore no fruit this year. 



This closes the excision experiments. The results varied considerably, 



but in no case did the removal of affected parts stop the progress of the 



disease. The symptoms appeared again the following season in all but 



two of the trees, and in these two they came back the second season.
