burning over the beds in the spring-, practical immunity is 

 secured from this, the most serious of the fungous diseases 

 of the strawberry. 



Blackberries and Raspberries. — The "Orange Rust'* 

 (Casoma) is rarely a very serious disease with us. Mr. 

 Plant reports it as exceptionally light during the past sea- 

 son. The only remedy is taking out and burning the dis- 

 eased plants. 



"Anthracnose" (Gloeosporium) is a more serious 

 trouble. It seems to be independent of weather conditions 

 and does very great damage locally. In other places it 

 may be almost unknown. A case was observed in Litch- 

 field County, where a large plantation was so seriously 

 diseased as to be apparently worthless. The owner was 

 advised to cut out the worst canes and to run a plow 

 between the rows, turning up the dirt over the diseased 

 stubs. This was done and a fine crop of fruit was secured. 

 A neighboring plantation which was sprayed with Bor- 

 deaux Mixture showed no benefit from the treatment. 

 This is usually the case. 



Cultural methods, as in the case above cited, seems the 

 only practical ones in this instance. 



Currants. — The "Leaf Spot" (Septoria) was reported 

 by Mr. Plant as very bad at Branford upon unsprayed 

 bushes. Where Bordeaux Mixture was used the disease was 

 entirely prevented. This is in line v/ith universal experi- 

 ence in the case of this trouble upon currants. 



VINES. 



Grape. — The "Anthracnose" of the grape (Sphaceloma), 

 like the similar disease of raspberries, seems to be common 

 only locally. V/liere the vines are kept thoroughly 

 sprayed for more common diseases they are reported as 

 practically exempt from Anthracnose. 



The "Downy Mildew" (Plasmopara) is always prevalent 

 where it is not held in check by Bordeaux Mixture. ]\Ir. 

 Plant reports that the disease appeared at Branford very 

 late in the season even on the sprayed vines. 



The "Powdery Mildew" (Uncinula) is a disease which 

 seems to be remarkably independent of the weather. Not-
