Diatomaceous Earth (DE)
All products containing DE sold by Green Harvest use 100% Food Grade Diatomaceous Earth. This is untreated, unheated agricultural diatomaceous earth not the diatomaceous earth used in swimming pool filters, which is dangerous and has no pest control properties.
Each product is packaged, marketed and registered by a different company who have chosen to offer this multi-purpose, safe product in a container, size and label suitable to a specific pest problem. All labels, MSDS, application suggestions are available on our website.

Diatomaceous Earth (DE) is a form of silica that can kill insects by desiccation, by absorbing their waxy, oily, outer layer. When this thin, waterproof layer is damaged, the insect or insect egg loses water and dies. DE also has microscopically razor sharp edges, which works as an abrasive sandpaper to kill the insects. This killing action is a mechanical not a chemical one. If kept dry, DE has an indefinite shelf life and remains effective for as long as it is present. DE, also called 'sharp sand', or 'fossil dust' is sourced from the fossilised remains of freshwater single-celled plants.

Uses: Internationally, DE has a wide range of uses in organic agriculture and household pest control. It is included in products which are registered, marketed and certified for the control of cockroaches, silverfish, ants, fleas, flies, ticks, lice, earwigs, aphids, white fly, beetles, loopers, mites, snails, slugs, leaf hoppers, and head lice. It is also used as an ingredient in biodynamic tree paste and in products for the control of internal parasites of stock: poultry, goats and sheep. Green Harvest uses it to protect stored vegetable seed organically.

New Insecticides Innovation
Probably the most effective naturally occurring protective powder is diatomaceous earth. Diatomaceous earth will control the pests as long as the powder remains. In this respect diatomaceous earth is an ideal pesticide; it is residual but non-toxic.

Food Grade does not mean it is a food, it simply means it can be added to food, ie parts per million to grain silos, or when mixed with feed or seed at 1 kg DE / tonne of seed. No DE product is registered for human consumption as a medicine or for use as a detox supplement.
In addition the manufacturer adds...
While diatomite is non-toxic for humans as well as livestock and poultry, we do not endorse or recommend its use as a human food supplement. This is because it is not prepared under the sterile conditions required for this.
