FUNGOUS PESTS ATTACKING THE STRAWBERRY 



Leaf Blight, Rust (Sphaerella fragariae) The 

 reddish or brown spots that come so abundantly on the 

 leaves of the strawberry in the spring or summer are 

 caused by this fungus. It grows most abundantly in 

 warm, moist weather, and when the plants are in a 

 weakened condition from any cause. 



Remedy To insure the best results from the use 

 of the bordeaux mixture, the leaves of the plants should 

 be dipped in it before they are set in the spring, and 

 the growing plants sprayed several times during the 

 summer. In the spring, before fruiting, the beds should 

 be sprayed once or twice before the blossoms open. 



Mildew (Sphaerotheca castagnei) The fungus 

 produces a light grayish growth on the surface of the 

 fruit and leaves in the spring that seriously checks the 

 growth of the plants and injures the berries. 



Remedy A vigorous growth of plant should be 

 produced by an abundance of plant food in the soil, and 

 the use of the bordeaux for the leaf blight will do 

 the rest.
