46 . STRAWBERRIES 
some seasons this disease is prevalent in strawberry 
growing districts, and it has proved most destructive 
in some parts of America. The first evidence of this 
fungus is found in dull spots on the strawberry leaves, 
these spots frequently running together to form irregular 
blotches. Presently these discoloured patches turn grey 
in the centre, soon becoming almost white, with dull red 
borders. Later in the season the spores (ascospores) 
are produced, while in the fading and infested leafage 
the mycelium of the fungus forms bud-like bodies, 
known technically as sclerotia. Both the spores and. 
sclerotia are capable of germination the following 
season. 
The effect of Strawberry Leaf-Spot is so to weaken 
the plants that the crop is more or less injuriously 
affected. A somewhat drastic method of getting rid of 
the pest is to cut away all the leafage immediately after 
the crop has been gathered, burning it, as well as the 
straw or litter that has been placed between the rows. 
Another method is to remove all flower spikes, old and 
badly diseased leaves, and runner growth, as soon as 
possible after gathering the fruit, burning all together ; 
following this by spraying the plantation with Bouillie 
Bordelaise about once a fortnight until winter begins. 
In spring, directly the new leaves begin to arise, 
commence spraying again, and continue at regular 
intervals until the strawberries begin to flower. 
INSECT AND OTHER ENEMIES OF THE STRAWBERRY 
Although there are several pests that attack straw- 
berries more or less viciously, none assume the propor- 
tions of a plague unless the situation or the cultural 
conditions provided are very much at fault. It is when 
grown under glass that strawberries soon become
