soap

Soap has been used as an old remedy to control pests. Salts and fatty acids are found in many soaps
which act as selective pesticides.

Method of preparation

Method #1: Mix 2 teaspoons mild
detergent with 4 liters of water.

Method #2: Mix 2 teaspoons mild
detergent with 4 liters of water.

Method #3: Mix 3 tablespoons of soap
flakes (not detergent) with 4 liters of water.
Method #4: Mix 1 tablespoon of
dishwashing detergent with 1 cup of
cooking oil, to make a stock solution. For a
gallon of spray, add 5 to 8 tablespoons of
stock solution to a gallon of water.

Method #5: Mix 2 1/2 tablespoons of liquid
soap to a gallon of water. Stir well

How to use

1. Add soap to water. Use mild soap or
potash-based soap.
2. Start with a lower concentration and
make adjustments of the strength after
testing on few infested plants.

3. Always try on few infested plants
before going into full scale spraying.
Soaps can cause burnt leaves on
sensitive plants, like cole crops and
certain ornamentals. Several
applications in short periods can
aggravate drying of leaves.

4. Apply on the infested plants
thoroughly, including the undersides of
the leaves. Spray early in the morning
or late afternoon.
