Dusting is superceding spraying for much control 
work and, for the home gardener, dusting is much more 
convenient. A small hand duster can be obtained in 
various sizes and styles, ranging from $1.25 up. For 
spraying, a small fruit jar container type will suffice 
for average home use. 
SOME COMMON CONTROL FORMULAS 
Formula 1—Aphids—Make spray by dissolving 1 ounce or 1/3 
bar laundry soap in a gallon of hot water and mixing in 1% tea¬ 
spoonfuls of nicotine sulphate. Soap and water often give good 
control. Spray on cloudy day or late afternoon. Give another 
application in a week. Aphids attack chrysanthemums, beans, cab¬ 
bage, cauliflower, cucumbers, currants, muskmelon, peas, potatoes, 
roses, spinach, tomatoes, columbines, calendulas, cinerarias, cosmos, 
delphiniums and snapdragons. 
Formula 2—Cutworms and Grasshoppers— 
Use the following : 
Bran . _ . 
1 quart 
Paris green 
- 
- 
1 level teaspoonful 
Ground orange or lemon 
- 
- 
i/j 
Sirup (Cheap table) 
- 
- 
2 teaspoonfuls 
Water ... 
- 
- 
1 pint 
Mix bran and paris green dry. Stir it and finely ground fruit 
into the water. Pour the sweetened liquid over the poisoned bran 
and mix thoroughly. Apply thinly where insects are feeding. Ap¬ 
ply in evening or early morning for grasshoppers. Apply in even¬ 
ing for cutworms. For cutworms, it can be placed under pieces of 
board or bark in small piles. Keep away from chickens. Repeat 
in three days if necessary. 
Formula 3—Red Spider—Spray with considerable force, using a 
mixture of 1 pound of ordinary glue dissolved in 10 gallons of 
water. This spider attacks evergreens, roses, raspberry plants and 
various other shrubs and trees. 
Formula 4—Bordeaux Mixture—This is the most widely used 
chemical for control of diseases and occasionally against insects. It 
is made by combing copper sulphate, hydrated lime and water, the 
proportions usually given as a formula as 4-6-50. Various college 
bulletins give directions as to making this in quantity, but for use 
by the average small home owner it is preferable to buy commercial 
formulas already mixed or ready to mix with water. Bordeaux 
mixture has many uses in addition to those given in the table 
following, for which see books and bulletins. 
Formula 5—Dusting Sulphur—Fine dusting sulphur, (not ordinary 
sulphur) is used alone for rust and mildew on many plants. A 
mixture of 90 parts dusting sulphur and 10 parts dry arsenate of 
lead is widely used for mildew, slugs, blackspot and leaf blotch on 
roses. 
Formula 6—Copper Lime Dust—By combining 20 parts monohy- 
drated copper sulphate and 80 parts fresh hydrated lime, a dust has 
been put on the market which when combined with dew makes the 
equivalent of bordeaux mixture. This is now used for leafspot on 
chrysanthemums, ivy, phlox and zinnias, for botrytis rot on prim¬ 
roses and begonias, for anhtracnose on pinks and for other disease.^. 
Formula 7—Miscible Oils—These oils, readily purchased at any 
supply store, are used as dormant sprays, just before growth begins 
in spring, on evergreens, deciduous trees and shrubs to control a- 
phids, soft scale insects and mites.
