Diatomite Physical Insecticide

It is pure in quality, light in weight, neutral in pH value, chemically inert, non-toxic and harmless

"Feifei" brand diatomite physical insecticide is a flocculent white fine powder made of high-purity natural diatomite through airflow drying, ultra-fine crushing and grading. Main characteristics of mineral composition: the content of amorphous diatom opal is more than 90%, and the content of crystalline mineral quartz is less than 3%. It meets the standard of natural edible grade (imported) diatomite stipulated by FDA. The product has the characteristics of pure quality, light weight, large specific surface, high porosity, strong adsorption, neutral pH value, chemical inertia and so on. It is different from the national standard for food safety - diatomite (GB / 14936-2012). After high-temperature roasting, the crystalline silicon content of the latter is as high as 30% (yellow roasted products) to about 60% (white melting roasted products). It can only be used as filtering and processing additives in contact with food, but can not be directly imported for consumption. "Feifei" brand diatomite physical insecticide is sterilized at 250 ° C and does not contain any chemical additives. As a physical insecticide for horticultural plants, pets and household pests, it is safe for people, plants or animals. It is a natural environmental protection insecticide product.

Insecticidal Mechanism

Diatomite physical insecticide is an efficient adsorbent product. It can keep solid powder when adsorbing 1.5 times its own weight. When it is sprayed on the branches and leaves, branches and stems of plants and the surface of planting soil, the tiny particles of diatomite will adhere to the body surface of pests. When pests crawl, they will be pierced by sharp spikes on the surface of diatomite, resulting in the dehydration and death of the body fluid of pests after being sucked dry by diatomite. The way of killing insects by diatomite is physical or mechanical. Pests will never produce antibodies to it and will not cause environmental pollution. Although the killing effect is slow, it continues. It is a non chemical insecticide that kills insects in a chemical way. Although it has quick effect, it is easy to produce antibodies, difficult to last, and will pollute the environment. This is the biggest advantage of diatomite insecticide.

Scope of application

1. All kinds of flowers, bonsai and other horticultural ornamental plants, crops, vegetables, melons and fruits, etc.

2. Physical insecticidal of pets such as cats and dogs and removal of cockroaches and termites at home.

Usage method

1. Spray with ordinary pesticide sprayer mixed with water: Pest Prevention (diatomite and water) 1:300 ~ 500; Insecticidal 1:100 ~ 200; However, do not mix water in excess of the proportion to prevent blocking the nozzle;

2. Cover the back of the branches and leaves when spraying, because most pests will inhabit the back of the branches and leaves. Otherwise, the insecticidal effect will be affected.
