Niagara Dust and Spray Mixtures 
KOLODUST. A new sulphur dust that you can 
see stick through wind and rain. Extreme 
fineness of particles, together with high toxic 
properties, make Kolodust the superior fungi¬ 
cide sulphur dust. Used for control of apple- 
scab, brown rot, and many other fungous 
diseases. 
KOLOTEX. Same type of sulphur as Kolodust, 
but combined with poison for control of chew¬ 
ing insects as well as diseases. 
KOLOFORM. The ideal summer spray for 
peaches, plums, etc., for control of apple-scab, 
brown rot, and other diseases. Will not burn 
when used at the rate of 7 pounds to 50 gal¬ 
lons of water. Mixes readily and stays in 
suspension. 
KOLOFOG. This colloidal sulphur spray is a 
special-processed spray and is non-caustic to 
fruit, foliage, and operator. While primarily a 
disease preventive, it has been known to arrest 
stubborn cases of scab after infection has 
occurred. It will mix with lime-sulphur spray- 
oils, nicotine sulphate, and arsenate of lead. 
DUO-BORDEAUX. Not a dry Bordeaux but 
materials for making real Bordeaux mixture, 
with every Bordeaux membrane fresh—ready 
to stick and protect. 
P. A. NICOTINE DUST. A 4 per cent Nicotine 
Dust for aphids, red bug, pearpsylla, cucumber 
beetles, etc. The best contact dust for con¬ 
trolling sucking insects. 
Weed-Killers 
ATLACIDE. A non-poisonous Weed-Killer to 
be used as a dust, or it can be dissolved in 
water and used as a spray. One pound is 
sufficient to kill 100 to 450 square feet of 
weeds and grasses. Kills poison ivy, quack 
grass, thistles, and many other kinds of 
troublesome weeds. Lb. 50 cts.; 3L2-Ib. can 
$1.50. 
DOLGE WEED-KILLER. A clear, concen¬ 
trated, super-strength liquid chemical which 
sinks into the ground, destroying the tops and 
roots of all existing growth. One quart makes

60 cts.; gal. $1.75; 5 gals. $8. 
PURFECK. Purfeck chickweed killer kills only 
chickweed and will not injure the grass,
