Controlling Diseases of Flowers 
ASTERS—Yellows—A disease that causes dwarfing of the plant and yellowing of the leaves. 
Plants have a bushy appearance. Wilt—This disease also turns foliage yellow. The stems are 
streaked in brown or black. Leaves also turn black. This disease is carried in the soil. Leaf 
Spot This disease causes brown spots on the leaves. These fungus troubles are partially 
controlled by spraying with Bordeaux Mixture once a week through the season. 
CALENDULAS—Caterpillars—There are several kinds that eat the foliage. Spray with 
Dutox, 2 tablespoonfuls to 1 gallon of water, to control these pests. 
CANNA—Leaf Roller—This is a caterpillar which feeds on the leaves and may be found 
with the leaf rolled around it. Saddleback Caterpillar—Another caterpillar which attacks the 
Canna is the Saddleback Caterpillar. These pests can be controlled by spraying or dusting 
with Dutox. 
CHRYSANTHEMUM—Leaf Spots—This is one of the worst diseases of Chrysanthemums. 
The spots are dark and circular; affected leaves turn yellow. Spray with Bordeaux Mixture. 
Red Banded Leaf Roller—The Red Banded Leaf Roller is one of the caterpillar pests attacking 
the Chrysanthemum. Spray or dust with Dutox. 
COSMOS—Rot—This rot develops a greenish-fuzzy growth on affected parts. Use Bordeaux. 
nilS—Borer—A pinkish-white worm with a brown head which burrows into the roots and 
crown of the plant. Spray new growth with 2 tablespoonfuls of Arsenate of Lead to 1 gallon 
water. 
LARKSPUR—Black Leaf Spot—This disease causes black, tarry spots in the leaves and stems. 
Spray with Bordeaux Mixture as soon as growth starts in spring. 
NASTURTIUMS—Aphis or Plant Lice—See Roses. 
PEONY—Bud Blight—This disease blasts the buds, rots the young shoots, affects the leaves 
at the tip, extending back in a V-shape; diseased part is brown. Use Bordeaux Mixture. 
Ants—Ants are common on Peony buds, but they do not damage the buds or plant. They feed 
on a sweet secretion from buds. Use Acme Ant Kill. Rose Beetles—Long-legged clay-colored 
beetles about one-third inch in length. Spray or dust with Dutox. 
PHLOX—Mildew—The surface of the leaves becomes covered with a white powder. This 
disease may kill the leaves. Spray with lVz 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 Florgard 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—Webworms attack many 
different flowers, shrubs and trees. It is one of the common caterpillars. Spray with Dutox 
or Arsenate of Lead. 
Scale Insects of Shade Trees and Shrubs 
Shade trees and shrubs about the home grounds are frequently infested with scale insects— 
the most common being Oyster Shell Scale, European Elm, Cottony Maple, Tulip, Pine-Leaf, 
Terrapin Scales, and San Jose Scale. 
Oyster Shell Scale—Is already described under Apple. It is a serious pest of Lilac, Poplar, 
Ash, Willow and ornamental Dogwood. Rusty Evergreens—During the hot, dry summer 
weather the Red Spider multiplies rapidly. The Red Spider is a minute light red insect. The 
injury caused by this insect is very conspicuous on Evergreens and the foliage becomes a 
rusty color. Spray infested Evergreens (including Cedars, Pines, Firs, Spruces, etc.) with 
Volck, Lime Sulphur Solution, or dust with Superfine Sulphur, when the temperature is 
below 90 degrees. 
CHEWING INSECTS OF TREES AND SHRUBS—Shade trees and shrubs are frequently 
attacked by certain leaf-eating insects as Bag Worm, Web Worm and Common Caterpillars. 
Nearly all shade trees and shrubs are attacked by some form of leaf-eating insect. Bag 
Worm—Is first noticed by a tapering bag % to 2 inches long suspended from twigs and 
leaves, within which is a worm that feeds on the foliage, all the time carrying the bag¬ 
like home with it. Most often found on Arbor Vitae, but may attack other shrubs or trees. 
Web Worm—Forms conspicuous webs inclosing skeletonized, browned leaves and hairy cater¬ 
pillars, usually in the fall. The unsightly nests or webs are easily recognized. Tussock Moth— 
The newly hatched caterpillars of the Tussock Moth are gorgeous creatures about an inch 
and a half long, with four dense white tussocks or brushes of hair on their backs. These cater¬ 
pillars feed on a variety of shade trees. All the above described chewing insects that attack 
shrubs and shade trees may be controlled by spraying thoroughly with Arsenate of Lead or 
Dutox just as soon as the insects appear. The upper and lower surface of all leaves must be 
covered with the spray material. Spraying must be done just as soon as any chewing insect 
appears.
