Organic Pest and Disease Control
by Julie Ferraro
by Julie Ferraro


November 14, 1999

I winced when talking to a neighbour one day, as he mentioned a chemical he used to rid aphids from his garden. When I suggested a few organic methods he might try, he looked at me, surprised. I often run into people who don't realize there are organic alternatives to prevent and eliminate pests and diseases in our gardens that are safer than chemical solutions and more effective in the long run.

Keeping the garden healthy with normal gardening tasks can have important effects on pest problems and diseases. In a well-managed organic garden, plants are healthy because they get plentiful nutrients from soil that's rich in organic matter and are naturally pest and disease resistant because they aren't stressed for water or light.

Here are a few cultural practices that can help prevent pest and disease problems.

  • Add organic matter to your garden every year. Nutrient-rich soil provides vigorous, healthy plants that resist pests and diseases naturally. Use the results of a soil test as a guide to creating a balanced soil that will encourage healthy crops. Compost especially is the best all-around soil conditioner and fertilizer you can add to your soil.

  • Grow pest-resistant crops. Some crops are less susceptible to disease and insect attack than others. Also, individual cultivars have been bred to resist specific diseases and pests.

  • Don't let plants suffer water stress. Don't wait until plants wilt to water; by then the plants are seriously stressed. Water in the morning so foliage has time to dry, preventing moist conditions which favour disease development.

  • Rotate crops and change their location in the garden every year. Rotating crops prevents pest and disease problems and reduces the buildup of soilborne pests and diseases.

  • Keep a clean garden. Many pests look for protection in plant debris. Clean up debris and fallen fruit throughout the season and always pull out any badly infested plants you notice during the growing season.

  • Cultivate your soil Turning the soil with a garden fork, tiller or hoe can help destroy the soil dwelling stage of many pests and expose them to the killing cold.

  • Encourage beneficial insects. There are several beneficial insects that can be used as controls. They can be attracted to your garden and many can be bought at garden centres or supermarkets in a dormant stage to be released into the garden. Here are a few.

  • Ladybugs (also called Lady beetles) and their larvae feed on aphids, mealybugs, soft scales, and spider mites

  • Lacewings - adults feed on pollen and nectar, and their larvae devour aphids, ants and other small insects.

  • Parasitic Wasps - adults feed on nectar, their larvae feed on aphids, mealybugs and other small insects.

  • Tachinid flies lay eggs on or near plant-chewing caterpillars. Larvae parasitize the caterpillars.

  • Spined soldier bugs attack caterpillars and grubs, including army worms and Mexican bean beetle larvae.

  • Ground Beetles take shelter under permanent mulches and plantings and eat up slugs, cutworms and other soil-dwelling pests.
  • Use homemade repellents. There are several homemade and ecologically sound repellents to be made. Here are a couple to try.

  • Leafhopper Bug Repellent
•¾ cup (175 ml) each fresh mint leaves

•horseradish root and leaves

•hot read peppers

•green onion tops OR

•6 cloves garlic

•2 qt + 1 cup (2L + 250ml) water

•2 tsp. Liquid soap (non-detergent)

Combine first four ingredients in food processor with 1 cup (250 ml) water. In bowl, combine the puree and 2 qt (2L) water. Strain. Stir in soap. Store in fridge. Makes 2 qt (2L) concentrate, which is enough for 2 gal (8L) of spray. Add 1 cup (250 ml) concentrate to 1 qt (1L) water to use as spray.

All-Purpose bug Spray This is a good deterrent against disease spores.

•8 jalapeno peppers

•8 cloves garlic

•1 qt (1L) water

Blend ingredients in food processor. Dilute 1 part mixture with 4 parts water

  • Use barriers. There are various barriers that can be used against pests such as floating row cover, copper flashing (effective against slugs as a chemical reaction takes place when slugs come into contact with copper, giving them a jolt), tin and aluminum collars (effective against cutworms) and crushed egg shells or oyster shells.
