Controlling crawling pests in crops without resorting to pyrethroids or neonicotinoids that leave residues on the harvest and against which insects develop resistance, while improving soil structure with a mineral that provides bioavailable silicon, requires natural diatomaceous earth of controlled purity with fine and consistent granulometry. This diatomite—also called diatomaceous earth, kieselguhr, or DE—is marketed by Gardese in its natural, uncalcined presentation, micronized in 20 kg bags, designed for organic farming, professional gardening, pest control in stables and for pets, and as an industrial absorbent.

Key Benefits

Physical insecticidal action without generating resistance: the microscopic edges of fossilized silica puncture the waxy cuticle of insects on contact and dehydrate them within hours, without active compounds against which the pest can mutate.
Contribution of bioavailable silicon to the crop: slowly released silicon strengthens plant cell walls, increases tolerance to water stress, and reduces attacks by sucking pests such as thrips and aphids.
Exceptional absorbent capacity: retains multiple times its weight in water and liquids, a useful condition for regulating water in substrates, controlling humidity in stables, and as an agent for oil or chemical spills in the workshop.
Inert mineral with no expiration date: being fossilized algae from millions of years ago, it does not decompose or lose properties with prolonged storage as long as it is kept dry, a direct advantage over organic products.
Compatible with certified organic production: natural diatomite is accepted by most organic farming standards, a critical condition for certified organic producers who need pest control without losing their certification.

Typical Applications and Uses

Control of ants, cockroaches, fleas, bed bugs, and crawling pests in horticultural crops and urban gardens.
Silicon supply and substrate structure improvement in professional gardening, nurseries, and organic production.
Humidity and odor control in stables, corrals, bird cages, and pet areas.
Industrial absorbent for oil spills, non-aggressive chemical liquids, and dry cleaning in mechanical workshops.

Quality and Durability

An inexpensive diatomite fails in two areas: the origin is of low purity with high clay and carbonate content (which reduces the abrasive effect against insects), and the granulometry is irregular (which leads to uneven application and unprotected areas). Gardese works with micronized natural diatomite of controlled purity, which separates a diatomaceous earth for serious agricultural operations from a generic bag that is ineffective against pests.

Also known as: Technical: amorphous diatomite, kieselguhr, natural diatomaceous earth, biogenic silica, diatomite, diatomaceous powder. In Dominican Republic and the Caribbean: tierra de diatomeas, diatomita, tierra blanca, polvo blanco contra hormigas. In other countries: diatomaceous earth (USA), DE (USA), tierra de diatomeas (LATAM), kieselgur (ES, DE), terre fossile (FR), diatomite (LATAM).
