 Antliracuosc 



Gloeosporium laeticolor Berk.

Brown Rot 



Sclerotenia fructigena 

 The brown rot is one of the most se- 

 rious and widespread diseases which is 

 known to attack the stone fruits. In 

 most of the jieach-growing districts of 

 the East and Middle West this is the 

 most serious disease, and in seasons of 

 frequent summer rain may cause enor- 

 mous losses. In the Northwest, on ac- 

 count of less frequency of summer rains, 

 the disease seldom appears in epidemic 

 form, but is not uncommon on the prune, 

 peach and cherry, and occasionally on 

 the apricot. 



Symptoms 

 The fruit is most commonly affected. 

 The disease appears first as small, dark- 

 brown decayed spots, which gradually in- 

 crease in size till the whole fruit is af- 



fected. The rot does not at first cause 

 any shriveling of the tissues, nor do the 

 spots become sunken. On the well de- 

 veloped spots one finds the spore-bearing 

 structures of the fungus that causes 

 the disease abundantly produced. These 

 consist of cushions of threads bearing 

 great numbers of spores in chains. They
