abundance just after midsummer, are the evidence of the presence of the 

 above injurious fungous disease. The spots, at first small and few in number, 

 increase in size till the entire leaf is involved, and the foliage shows the effect 

 of a parasite's presence by shrivelling and withering. This loss of foliage 

 is a very serious matter, often coming early enough to materially lessen the 

 crop, and taking place at a time when the plant should be making new 

 runners for the next rear. The fungus is carried over winter by means of 

 spores and by means of mycelium (representing the vegetative portion of 

 the parasite) contained within the leaves. Some varieties are affected much 

 more than others. It has been generally noted that strawberries are affected 

 to a greater extent on sandy soil than on clay loam. 



TREATMENT. Bordeaux mixture prevents this disease, and on planta- 

 tions where the single crop system is followed this is the most practical and 

 effective remedy. When two crops are taken from the plantation, mowing 

 and burning the leaves on the rows immediately after the season of berry 

 picking closes, is the practice in some localities. 



MILDEW (Sphaerotheca Castagnei Len.). In dry seasons this fungus, 

 which causes the leaves to curl, covering them with a thin, cobweb-like 

 coating, lessens the crop very materially. Like gooseberry and grape mildew, 

 the fruit is also attacked.
