PRATT’S INSECTICIDES 
D-X INSECT SPRAY —D-X containing 
rotenone and pyrethrum, for years, has 
been one of the most effective and popular 
garden sprays. Piperonyl cyclonene, a 
powerful, non-poisonous insecticide, has 
been added to the D-X formula. Piperonyl 
ecyclonene increases the killing power of 
rotenone and pyrethrum, also giving 
these toxic ingredients longer residual ac- 
tion. Controls aphis, leaf hoppers, thrips, 
tent caterpillars, canker worms, Mexican 
bean beetles, Sawfly caterpillars, coddling 
moth, Japanese beetles, red spider and 
many other sucking and chewing insects.

spreaders, and is economical and highly effective. Use 1% 
pints to 100 gallons of water. (% pts. 55e) (qts. $1.25) (5 ga's.

FUNGICIDES 
DIATHANE Z-78—A fungicide for the control of early and 
late blight, downy mildew, moid and mildew rust, anthac- 
nose on tomatoes, celery, cucurbits, potatoes, beans and 
gladiolus. Use 1 lb. to 100 gallons of water. (3 Ib. pkgs. 
$3.25), F.O0.B. Denver. 
TRI-BASIC COPPER SULPHATE (53% Copper)—lIs 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 lb. 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. kag $2.00) (48 
ib. case $12.00), F.0.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 Ib. 
bag $2.25) (48 lb. case $14.00), F.O.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.
