The Use of Diatomaceous Earth as a Natural Alternative to Chemical Pesticides in Agriculture and Horticulture
Diatomaceous earth (DE) is a natural, non-toxic alternative to chemical pesticides in agriculture and horticulture. It controls insects through a physical mechanism, reducing reliance on synthetic chemicals while remaining safe for humans, animals, and the environment. Effective on a wide range of pests, DE can be applied to crops, gardens, stored produce, and poultry bedding. Using DE supports sustainable pest management, decreases chemical exposure, and integrates easily into organic and low-chemical farming systems.
🌱 Australian Diatomaceous Earth: Nature’s Pest Shield for Safer Agriculture
1. What Is Diatomaceous Earth & Why It Works Diatomaceous Earth (DE) is made of fossilized silica shells from freshwater marine algae—composed of around 80–90% amorphous silica, tiny abrasive particles that physically disrupt insects’ exoskeletons, causing dehydration and eventual death. Because it’s a mechanical mode of action, pests cannot develop resistance, unlike with synthetic pesticides. […]
