quite extensively in treating Seed Potatoes.

Rotenone Dusts—We are manufacturing 
our own Rotenone Dusts. This fresh mixing 
assures you of getting fresh materials at all 
times. The killing qualities of this new non- 
poisonous dust deteriorate very rapidly and 
it is therefore very essential to get fresh mix- 
ed dusts. We are mixing these rotenone dusts 
in every desirable strength and are also mak- 
ing the dusts with the correct proportion of 
sulphur for certain uses. Due to the fluctua- 
tions in prices of raw materials we cannot 
publish prices. Prices on request.

thrum and sulphur for general dusting pur- 
poses. Very efficient for control of cabbage 
worm, bean beetles, flea beetle, leaf hoppers,

ris, Pyrethrum and Sulphur in stronger pro- 
portions than in three way dust. Will give 
better control in severe cases of insect in- 
festations.

marily in the control of blights on vegetables,
