Diatomaceous Earth for Pest Control
Least toxic physical and chemical solutions are often part of an IPM program. Various forms of amorphous silica are commonly used as part of this strategy. Diatomaceous earth and silica gel are used in various physical formulations with or without added pesticide. The type of silica and the formulation depend on the target pest. In this issue advantages and disadvantages of diatomaceous earth a...
متن کاملCharacterization and adsorption properties of diatomaceous earth modified by hydrofluoric acid etching.
This work was a study of the chemical modification of diatomaceous earth (DE) using hydrofluoric acid (HF) solution. Under the experimental conditions investigated, it was found that HF under controlled conditions significantly etched inward into the interior of the existing pore structure in the clay mineral due to its high content of silica, leaving a framework possessing a larger BET surface...
متن کاملNew perspectives for the application of diatomaceous earth to the remediation of polluted waters and soils
Research effort dealing with the remediation of leaching waters polluted to prevent further damage of surface and ground water reserves are needed. For this purpose, diatomaceous earth, an inexpensive, available and no pollutant material, has been tested for retention of persistent pollutants, such as heavy metals (cadmium) and pesticides (atrazina and chlorpirifos). It has been used as undergr...
متن کاملBioactivity of diatomaceous earth to Sitophilus zeamais (Coleoptera: Curculionidae) in different application conditions
The objective of this study was to evaluate the insecticidal activity of diatomaceous earth (DE) at different ambient temperatures on adult Sitophilus zeamais and progeny, using different doses and exposure periods. The experiments were performed in Petri dishes containing 40 g of the whole corn kernel, treated with DE at doses of 0, 0.25, 0.5 and 1.0 kg Mg-1. Each dish was infested with 25 S. ...
متن کاملMortality among workers in the diatomaceous earth industry.
A cohort mortality study was conducted among workers from two plants in the diatomaceous earth mining and processing industry in California. Diatomaceous earth consists of the skeletal remains of diatoms. Exposure to amorphous (non-crystalline) and crystalline silica in the form of quartz results from open pit mining and exposure to crystalline silica (principally cristobalite) occurs in the pr...
