Garlic: The strong odor and sulfur compounds in garlic repel a wide range of pests, including aphids and spider mites. Blend garlic cloves with water, let it steep, and dilute before spraying. Chili (Pilipili): Capsaicin, the active ingredient in chili, acts as an irritant to many insects. Grind chilies, mix with water and a little soap (as an emulsifier), and spray to deter pests. Aloe Vera: Beyond its medicinal uses, aloe vera can strengthen plant immunity and act as a mild deterrent.

2. Formulation Ratios and Blending Techniques

Proper formulation is crucial for efficacy. While specific ratios vary, a general guideline involves:

Neem Concentrate: 1kg of crushed neem seeds/leaves soaked in 5-10 liters of water for 24 hours. Dilute this concentrate (e.g., 1 part concentrate to 5-10 parts water) before spraying. Garlic Spray: Blend 500g of garlic cloves with 2-3 liters of water. Let it sit for a few hours, then strain. Dilute 1 part concentrate to 10 parts water. Chili Solution: Blend 250g of fresh chilies with 2 liters of water. Add a tablespoon of liquid soap (like Omo or Sunlight) to help it stick to leaves. Dilute 1:10 with water. Combining Ingredients: For broader spectrum protection, you can often blend these solutions. Start with small batches to test compatibility and plant reaction.

Understanding your soil is as important as understanding your biopesticides. Healthy soil produces resilient plants less susceptible to pests.
