Ingredients and Preparation
Required Ingredients:
Garlic Cloves
- Garlic contains sulfur compounds that have natural pesticidal and antifungal properties.
- Use about 1 bulb of garlic for a strong solution.
Chili Peppers (Fresh or Dried)
- Chili peppers contain capsaicin, which repels many pests.
- Use 2-3 fresh chili peppers or 1 tablespoon of chili powder.
Water
- Acts as the base for the spray solution.
- Use 1 liter of water.
Optional: Mild Soap
- Helps the mixture adhere to plant leaves and enhances the spray’s effectiveness.
- Use a few drops of mild soap.
Preparation Steps
Blending and Mixing
- Peeling and Crushing Garlic: peel 1 bulb of garlic and crush the cloves to release the active compounds.
- Chopping Chili Peppers: If using fresh chili peppers, chop them finely. If using chili powder, measure 1 tablespoon.
- Blending Ingredients: Combine the crushed garlic and chopped chili peppers (or chili powder) with 1 liter of water in a blender. Blend the mixture thoroughly until it is well combined.
Straining the Mixture
- Using a Fine Mesh Strainer or Cheesecloth: Strain the blended mixture through a fine mesh strainer or cheesecloth to remove solid particles. This step is crucial to prevent clogging of the spray bottle nozzle.
- Collecting the Liquid: Collect the strained liquid in a clean container, ensuring that it is free of any large particles.
