compacted masses. It has been found largely on the 

 Agawam blackberry and some of the red raspberries. It 

 appears late in the summer or early autumn, and if in such 

 abundance as it has appeared this fall will seriously affect 

 the growth of the varieties attacked. 



For the prevention of these three fungi we would spray : 

 first^ just before the leaves unfold, with the Bordeaux mixt- 

 ure, taking care to wet every cane thoroughly ; second, 

 when the leaves have unfolded and just before the blossoms 

 open, spray with the same. Should the raspberry leaf blight 

 appear before the fruit is gathered, one spraying must be 

 made with the ammoniacal carbonate of copper; but if it 

 does not appear, no further application need be made until 

 the fruit is harvested, when a thorough spraying with the 

 Bordeaux mixture will prevent the spread of this disease and 

 the fall orano-e rust. 



Steawberry. 



The larvfe of the May beetle {Lachnosierna fusca) and the 

 black paria {Paria aterrimd) are the two most injurious 

 insects attacking the strawberry ; and the strawberry leaf 

 blight (^Sphoerella fragarice') is the only well-known fungous 

 disease. 



The May beetle laj^s its eggs in turf land, old straw- 

 berry beds, weedy land and under trees and shrubs, where 

 the larv83 will find an abundance of young and tender roots 

 to feed upon, and never in clean, well-cultivated ground. 

 From the time the eggs are laid to its full development into 

 the beetle state it requires two or three years, the larvse 

 feeding all this time, and doing much injury. 



The black paria lays its eggs near the crown of the straw- 

 berry plant, the larvfe feeding on the roots, while the per- 

 fect beetle feeds on the young leaves, making small punctures 

 like shot holes. 



The strawberry leaf blight first appears as small reddish- 

 brown spots on the leaves, which, if abundant, as they are 

 on many varieties long in cultivation, seriously check the 

 growth of the plant, and the fruit is of small size. It may 

 appear at any season of the year if the weather is favorable, 

 but generally appears nea?r fruiting time and during July 

 and August.
