PARA-SCALECIDE 
FOR PEACH BORERS 
Para-Scalecide is a combination of paradichlorobenzene and 
Scalecide, which makes a liquid application for peach borers 
that is safe and effective on young or old peach trees. It is in 
great demand wherever peaches are grown. 
Para-Scalecide is diluted 1 gallon to 7 gallons of water and 
poured against the base of the trees 4 to 6 inches above the 
ground in the fall or spring. It requires approximately 4% 
pint for 1 to 2 year old trees, 1 pint for 3 year old trees, and 
1% pints for older trees. The diluted Para-Scalecide is also 
painted on the body and main limbs for lesser peach borers, 
and for borers on plum, cherry and apple trees. (qts. $1.50)

FUNGICIDES 
DIATHANE Z-78—A fungicide for the control of early and 
late blight, downy mildew, mold and mildew rust, anthac- 
nose on tomatoes, celery, cucurbits, potatoes, beans and 
gladiolus. Use 1 lb. to 100 gallons of water. (3 lb. pkgs. 
$3.25), F.0.B. Denver. 
TRI-BASIC COPPER SULPHATE (53% Copper)—Is effectively 
used for the control of persistent diseases, such as blight on 
potatoes, tomatoes, celery and sugar beets, and black rot on 
grapes. In sprays this fungicide should be used at the con- 
centration of one-half or less of the quantity of copper sul- 
phate ordinarily used in Bordeaux Mixture. In dusts the rec- 
ommended quantities of TRI-BASIC plus tale or clay has 
largely replaced the old fashioned Copper-Lime dusts. This 
is especially true where DDT is recommended inasmuch as 
it is generally recognized that the presence of excess lime 
greatly reduces the effectiveness of the insecticide. (6 Ib. bag 
$2.00) (48 Ib. case $14.40), F.0.B. Denver. 
26” COPPER FUNGICIDE (26% Copper)—This material is 
suitable as a spray for apples, cherries, pears, grapes and 
other fruits. For a spray we suggest from 2 to 2% pounds 
to be used per 100 gallons of spray material, plus equal quan- 
tities of lime. Results show that this material is very effi- 
cient in controlling scab, blotch, fruit spot, bitter rot and 
other diseases on fruits and vegetables. (6 Ib. bag $2.00) (48 
Ib. case $12.00), F.O.B. Denver. 
“34” COPPER FUNGICIDE (34% Copper)—This fungicide is 
recommended for use either as a spray or dust. As a dust, 
it is effectively used on melons, cucumbers, tomatoes and 
other truck crop vegetables. ‘‘34’’ Copper Fungicide is com- 
patible with organic insecticides such as DDT, Pyrethrum, 
Derris Cube and Black Leaf 155 and Nicotine Sulphate. (6 lb. 
bag $2.25) (48 lb. case $14.00), F.0.B. Denver. 
YELLOW CUPROCIDE—A highly effective spray material in 
the form of a dry powder. It suspends readily in water. For 
control of damping-off in its second stage, spray seed bed 
immediately after planting seed and once more before seed- 
lings appear. Spray seedlings every 7 to 10 days. Especially 
good for the control of blight and leaf spot on celery, toma- 
toes and potatoes; 3 lb. package makes 200 gallons of spray.
