Reports to the Board of Agriculture. 47 
the Corn Weevil, the climate not being warm enough for C. or y zee to 
flourish to any extent. 
Treatment. 
1. Well clean out the barn or other building in which the 
beetles have been at work ; walls, ceiling and floors should be 
cleaned, washed with whitewash and soft soap and all refuse burnt. 
2. Keep grain in bulk and constantly stir. 
3. Keep well ventilated with cold air and plenty of light. In a 
warm climate ventilation would do no good, but cold air soon checks 
their reproductive powers. 
4. If the store house or barn is fairly air-tight, close up all 
openings where possible and then fumigate with bisulphide of carbon. 
Evaporate 1 lb. of the bisulphide of carbon to every 1000 cubic feet 
of space (about). Put the carbon about the surface of the grain in 
flat saucers — the heavy fumes penetrate through the grain and kill 
all forms of life, but do not harm the grain — leave closed for 
twenty-four hours and then well ventilate and move the grain over. 
If the grain could be treated in closed bins so much the better — 
1 lb. of the bisulphide to every 100 bushels of grain is sufficient, 
leaving for twenty-four hours. 
A caution must be given that this substance is : — 
1. Inflammable. 
2. Both the fumes and liquid poisons. 
A detailed report on this pest is given in the Journal of the S. E. 
Agricultural College, No. 5, pp. 11-21, 1897. 
The infested grain given to poultry would do no harm — the birds 
would devour the insects as well. 
FUNGOID DISEASES. 
Fungoid Disease in Black Currant Leaves. 
(Septoria ribis.) 
The currant leaves sent to the Board of Agriculture from Wickham 
Market, Suffolk, are invaded by a fungus which produces so-called 
Currant Bust or Leaf Spot. The fungus is apparently Septoria ribis. 
This disease attacks all kinds of currants, and appears, as a rule, 
about the beginning of July. 
It is first noticeable as small brown spots. Dull whitish spots 
also appear, but these may be due to another fungus. Both may be 
treated, however, as one, so far as remedies go.
