yellowing- of the foliage in every case proved to be due to 

 the jx^acii borers, drouth or some other weakening effect 

 on the trees. Premature ripening of the fruit from simi- 

 lar causes has also lead many to believe their trees to 

 be affected with the yellows. The absence of red spots 

 on the skin and red streaks through the flesh of the fruit 

 should serve to relieve uneasiness in such cases. 



The cause of yellows is yet und'^termined, but it is 

 detinitely known that it is a disea; e and can be com- 

 municated from tree to tree and from orchard to orchard. 

 Ex])eriments have shown that it can be communicated 

 to healthy trees through buds taken from diseased trees, 

 but the manner of its natural spread from tree to tree is 

 yet unknown. It is known, however, that from scattered 

 cases in the orchard it will gradually spread over the en- 

 tire orchard and completely destroy it if left unmolested. 



Prevent ion. — Since yellows is an incurable disease, we 

 can only look to preventive measures for protection. 



(1) Peach trees should not be obtained from nurser- 

 ies located immediately in infested sections. Suc^i stock 

 is liable to develop yellows after planting out. 



(2) Peach pits from affected trees should never be 

 planted. They may reasonably be expected to convey the 

 disease to the young stock. 



(3) Whenever the disease appears in an orchard 

 every affected tree should be rooted up and burned. Sim- 

 ply cutting off affected parts is not suflScient. The virus 

 exists in the apparently healthy parts and would soon 

 develope the symptoms of yellows. The whole tree, root 

 and branch, must be destroyed. 



PEACH AND PLUM ROSETTE. 



Similar to the yellows is a disease known as ''Rosette" 

 from the peculiar tufts into which the leaf buds grow 

 on trees under the influence of the disease. It attacks 

 peaches and plums and is quite generally distributed 

 over the northern portion of Middle Georgia, extending 

 from Augusta to the Alabama line, and from Macon to 

 some distance north of Atlanta. The writer has quite 

 thoroughly worked the State over and has never found 

 it south of Macon nor in extreme North Georgia. It also 

 occurs, although to a limited extent, in Eastern Kansas 

 and in Western South Carolina. It seems to be most
