Diatomaceous Earth or D.E. is a white amorphous silica powder derived from fossilized remains of Diatoms (hard shelled algae) found in fresh and salt water deposits. D.E. is commonly used in pool filters due to its microscopic porosity, which captures dirt and algae.
In addition, D.E. is also used as an insecticide by organic growers and for grain storage. In fact, a number of tests have shown it to be more effective than Malathion in grain storage, particularly over the long term.
Diatom shells are covered with sharp spines which will penetrate the flesh of the insect, causing fluid to escape, dehydrating it. In addition, it absorbs lipids from the waxy outer layer of the insect’s exoskeleton, also causing them to dehydrate. Although pest control is not immediate, (it may take a few days), it is the ideal insecticide because it is non toxic to humans and animals and it provides residual protection. As long as the powder remains on the plant, it protects it.
Pesticide quality D.E. should be 97% amorphous silica, which by the way does not cause silicosis.
One of my colleagues, who is also one of the largest organic vegetable grower in Florida, uses it extensively with great results. This speaks volume of D.E. considering the bug pressures we encounter in Florida’s hot climate.
If you grow vegetables in your garden, you may want to consider D.E. to protect your plants.
