talks SULFOCIDE 
S ULFOCIDE is a pure pentasulphirle of 
sodium ill liquid form, held together 
so lightly that it breaks up by the action 
of the air immediately after its application 
to the plant, leaving a deposit of true col¬ 
loidal sulfur on the fruit and foliage. This 
sulfur is so fine that it may be dissipated 
faster than coarser sulfur, yet it adheres 
firmly for days and its fungicidal action is 
extremely powerful and highly penetrative. 
Sulfocide is strong enough to he effective 
against such resistant diseases as bitter rot 
of apples and black rot of grapes, yet it is 
mild enough to be safe at the same dilu¬ 
tion on many delicate flowers. 
Sulfocide mixes perfectly with many sprays 
such as Summer Scalecide, Black Leaf 40, Cal¬ 
cium and Magnesium Arsenates. However, Sulfo¬ 
cide can only he mixed with Arsenate of Lead 
when a casein lime spreader, such as fresh Kay so, 
is mixed in the water in the spray tank first, the 
arsenate of lead second and Sulfocide last. Use 
only Kayso manufactured during the season it is 
to he used, as old Kayso will not prevent burning 
from his combination. If these precautions are 
observed, Sulfocide makes one of the safest sum¬ 
mer sprays. When used in the calyx and later 
sprays it produces apples of high color and finish 
and actually increases the codling moth kill of 
arsenate of lead. Ask for special spray programs. 
Spraying Suggestions. Use Sulfocide 1 to 200 
as a general purpose fungicidal spray. Use Sulfo¬ 
cide on apples and pears for scab, leaf spot and 
rot; on peaches, cherries and plums for brown 
rot and leaf spot. Spray grapes and small fruits 
with Sulfocide at the same strength, avoiding as 
far as possible hot weather spraying (above 85°). 
Use Sulfocide 1 to 200 on vegetables, especially 
beans for anthracnose, on tomatoes for rot, on 
cucumbers for wilt and blight, on egg plants, 
peppers, potatoes, etc. Use Sulfocide 1 to 200 on 
roses for mildew, on hollyhocks for rust, peonies, 
carnations and other flowers for mildew, blight 
and leaf spot. 
A little soap, 3 or 4 pounds to 200 gallons, 
with Sulfocide acts as a spreader, increases its 
effectiveness, and makes the spray almost invisi¬ 
ble. Spray peaches, cherries and other perishable 
fruits with .Sulfocide and soap just before pick¬ 
ing. It will do wonders in preventing rot enroute 
to market. The same holds true for grapes, and 
vegetables, especially beans for anthracnose and 
tomatoes for mold. It is harmless, tasteless and 
does not show on fruit, except faintly on fruit 
such as black cherries. 
Remember that Sulfocide is at its best when 
used without the presence of arsenate of lead, 
in the mixture, on the foliage, or in the spray 
fittings. 441-50-11-34
