68 MODERN STRAWBERRY GROWING 
ceptible to this disease, although some varie- 
ties, are more resistant than others, especially 
Marshall and Brandywine, while Bederwood 
has great susceptibility. 
The remedy is bordeaux mixture sprayed 
on just before the flowers open, followed 
(if the disease is seriously prevalent) by 
mowing off and burning the leaves after the 
fruiting season is over. On small beds the 
diseased leaves may be removed by hand. 
These remedial measures will also control 
the other less important ones, which need 
not be discussed in detail. 
SPRAYING MIXTURES 
Commercial growers have become quite 
familiar with the preparation of bordeaux 
mixture, but for the benefit of those who are 
growing plants on a smaller scale this account 
of the mixing is given. 
I believe in being on the safe side in the 
preparation of a spraying mixture, believing 
that a few pennies spent at this time may in 
the end save many dollars. The standard 
formula is: 
4 pounds Copper sulphate 
6 pounds Lime 
50 gallons Water.
