garlic as pectiside
Garlic originated in Central Asia and has now spread across the world. For use as an insecticide it should not be grown using chemical fertilisers. This is because heavy doses of fertiliser reduce the concentration of the effective substances in the garlic. It has anti-feedant, bacterial, fungicidal, insecticidal, nematicidal and repellent properties.
Preparations
• Garlic spray
Blend 100 grams of grated and crushed garlic cloves, 0.5 litres of water and 10 grams of soap (Use potash based soft soap that is used for washing dishes and not the modern washing powders that contain caustic soda which will harm plants). Mix well. Strain the mixture through a fine cloth.
Dilute the solution in 5 litres of water.
How to use: Mix the solution well before applying to the affected plants. Use as a spray or sprinkle using twigs or grass tied together to form a whisk. For best effect, use the mixture immediately.
Garlic is effective against a wide range of diseases and insects at different stages in their life cycle (egg, larvae, adult). This includes ants, aphids, army worms, caterpillars, Colorado beetle, diamondback moth, pulse beetle, whitefly, wireworm, false codling moth, imported cabbage worm, khapra beetle, mice, mites, moles, Mexican bean beetle, peach borers and termites as well as fungi and bacteria.

Nematodes can also be controlled by drenching the soil with garlic liquid.
However this method may also kill many beneficial soil bacteria and insects.
Garlic is effective against so many pests and diseases that different strengths may need to be experimented with.
Note: The taste of garlic will remain on sprayed plants for one month after spraying so it may be best to avoid spraying near harvest time. HDRA - the organic organisation, Ryton Organic Gardens Coventry, CV8 3LG, UK
