108 GARDEN FOES. 



to suddenly die when the leaf-buds begin to burst open, 

 or when the flowers aj^pear, or soon after the fruit has 

 formed. The mycelium of the fungus penetrates the 

 tissues of the stems first at the base, and then spreads 

 upwards. Each spring the fungus becomes more active, 

 the bark eventually cracking and displaying fluffy tufts of 

 mould. It appears that the disease also attacks the 

 leaves, causing them to turn yellow at the edges and 

 to fall off. It also spreads to the fruit, causing a brown- 

 ing of the skin, and the eventual rotting of the berry. 



liEMEDiEs. — Wherever branches die suddenly or wither, 

 or the leaves tuvn yellow at the edges, and the berries 

 assume a brown hue, cut out the affected parts and 

 burn them. Indeed, it would be well to burn the whole 

 tree. As a preventive spray with a solution of copper 

 sulphate, 41b. to 100 gallons of water, just before the 

 buds burst. A further spraying with Bordeaux mixture 

 (Formulae Nos. 20 or 21) as soon as the berries are formed 

 is also recommended. 



Gooseberry Leaf Cluster Cup (^Ecidium Grossu- 

 larii)e).--This disease may easily be recognised. Both 

 leaves and fr\iit when infested with it are dotted with 

 little round bodies, having white jagged edges and bright 

 orange centres. The latter are the spores, by means of 

 which the fungus is perpetuated. 



Kemedy. — Remove the infected leaves and fruit, and 

 burn them. 



Gooseberry Leaf Mildew (Microsphaera Grcssu- 

 lai'iie). — This minute fungus develops on the under sur- 

 face of the leaves of gooseberries, covering them with a 

 dense white mould. It is not a serious pest, but should 

 nevertheless be got rid of wherever or w^henever it appears. 



Kemedy. — Spray the foliage, when attacked, with a 

 Sulphide of Potassium Solution (No. 23).
