HOW TO IDENTIFY PESTS OF VEGETABLES 
BEANS 
ANTHRACNOSE—Attacks the leaves and the pods, forming roundish discolored areas with 
a purplish border. Use Bordeaux Mixture to control this disease. 
MEXICAN BEAN BEETLE—The adult beetles are oval shaped and pale yellow to brownish 
in color with sixteen black spots. The young beetle is yellow in color and spiny. It is 
essential that spraying or dusting should be on the upper and lower sides of the leaves. Use 
Dutox for either spraying or dusting. 
CABBAGE, CAULIFLOWER, COLLARDS 
THE CABBAGE WORM—Is that greenish-yellow caterpillar that feeds on the leaves. The 
adult is a white butterfly that is often seen around the cabbage. This butterfly lays its eggs 
on the leaves and the eggs hatch into the Cabbage Worm. 
THE CABBAGE LOOPER—It crawls like a measuring worm, is green in color and feeds 
the same as the Cabbage Worm. Dutox will control both of these pests. 
CANTALOUPES. CUCUMBERS. WATERMELONS, SQUASH 
STRIPED AND SPOTTED BEETLES—Are yellow beetles, distinguished by three longitu¬ 
dinal black stripes or twelve black spots. Dust with Dutox, using a dust gun. 
LEAF BLIGHT—Is a disease sometimes called rusi. it causes brown spots on the leaves. 
ANTHRACNOSE—This disease affects the leaves and stems in the form of dark sunken 
spots. Both of these pests can be controlled by spraying with Bordeaux Mixture. 
POTATOES 
COLORADO POTATO BEETLE—POTATO BUG—This yellow-black striped beetle comes 
out of the ground where it spent the winter just as the Potato plants are coming up. The 
beetles feed for a short time on the young plants and then lay masses of orange-colored eggs 
on the underside of the leaves. These eggs hatch into dark red young beetles and they 
proceed to eat the Potato vines. 
THE FLEA BEETLE—Is a small black jumping insect that eats holes in the leaves of the 
plant. Control with Calcium Arsenate, Arsenate of Lead and Paris Green. 
LEAF HOPPERS—Are small pale yellowish-green hopping insects that attack the Potato on 
the underside of the leaves. This insect causes the leaves to brown, which in time will 
kill the plants. 
BLIGHT—Is the most destructive Potato disease. This disease turns the leaves black and 
tends to rot the growing Potatoes. Blight attacks both early and late plantings. Bordeaux 
Mixture will control Blight and Leaf Hoppers. 
TOMATOES 
TOBACCO WORM ON TOMATOES—This insect is a green caterpillar from two to four 
inches long with a horn at its posterior end. It will eat all the leaves off a plant in a few days 
unless the plant is sprayed or dusted. Use Calcium Arsenate, Dutox or Arsenate of Lead. 
Full directions on package. 
TOMATO FRUIT WORM ON TOMATO—A grayish-black worm which bores into the tomato, 
sometimes damaging 90% of the crop. Dust with Dutox when blooms appear and apply 
every 14 days until two weeks before harvest. 
Controlling Diseases of Flowers 
PHLOX—Mildew—The surface of the leaves becomes covered with a white powder. This 
disease may kill the leaves. Spray with 1% to 2 tablespoonfuls of Dry Lime Sulphur to 1 
gallon water, or dust with Superfine Sulphur. Leaf Spot—This disease causes brown spots 
on the leaves. Spray with Bordeaux. 
ROSES—Black Spot—This disease causes large black circular spots on the leaves. Dust with 
Floragard or spray with Bordeaux. Brown Canker—This disease shows up as purple spots 
on the stem and leaves. The blossoms are often attacked. Spray with Bordeaux Mixture. Cater¬ 
pillars—There are several different kinds of caterpillars that attack Roses. The stinging Rose 
Caterpillar is one. Dutox will destroy all caterpillars. Mildew—This disease covers the leaves, 
buds and young shoots with a white, flour-like mold. To control this, dust once every five 
days with Floragard. Leaf Roller—Leaf Rollers often attack Roses. The Olique Banded 
Leaf Roller feeds on the leaves and buds. To control this pest dust with Floragard. 
Rose Scale—A gray or whitish circular scale that readily sloughs off. Spray in the early 
spring before the buds open or in late fall after the leaves are off, with Volck or Oil Emul¬ 
sion. Aphis or Plant Lice—These are small, soft-bodied insects. They are green, red and 
black in color and cluster around the young shoots and under the leaves, causing the leaves 
to curl under. These pests attack every kind of flower and shrub. To control them, spray 
regularly once every four or five days with Evergreen or Black Leaf 40. 
SNAPDRAGON—Blight—This disease causes yellow spots on the leaves. Later they turn 
dark. Anthracnose—This disease is like blight. Spray with Bordeaux Mixture. Rust—One of 
the most serious diseases of Snapdragons; rusty brown pustules of spores formed on leaves 
and stems. Use Floragard or Superfine Sulphur. 
ZINNIA—Leaf Spot—This disease causes large black spots on the leaves, which can be con¬ 
trolled by using Bordeaux Mixture. Web worms or Caterpillars—Web worms attack many 
different flowers, shrubs and trees. It is one of the common caterpillars. Spray with Dutox 
or Arsenate of Lead. 
HOW TO CONTROL INSECTS AND DISEASES OF PECANS 
PECANS are attacked by scale, scab, leaf blotch, crown gall, etc. The following is an excellent 
spray program for combating all the diseases and insects of pecans: 
DORMANT SPRAY—For Scale Insects. While trees are completely dormant, spray with 
Buchanan’s Oil Emulsion at the rate of 5 gallons to 45 gallons of water. 
FIRST SUMMER SPRAY FOR SCAB, CASE WORM, CATERPILLAR, LEAF SPOT AND 
APHIDS—Apply just after fruit has set. Use prepared Bordeaux at rate of 8 pounds to 
50 gallons water, 2 pounds hydrated lime and U /2 pounds Arsenate of Lead. Add to this 
% pint Black Leaf 40.
