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 کاملGrain surface-layer treatment of diatomaceous earth for insect control.
This paper describes an alternative method to synthetic insecticides used for protection of stored agricultural products the purpose of which is to minimise the everyday human exposure to those chemicals. The method uses diatomaceous earth which is practically non-toxic to humans and fully acceptable for the environment. Fifty and 100-cm-deep layers of Hard Red Spring wheat Triticum aestivum (L...
متن کاملQuantification of historical dust exposures in the diatomaceous earth industry.
Quantitative estimates of dust exposure in a diatomaceous earth (DE) mining and milling operation have been derived based on air sampling records for the period 1948-1988. A total of 6395 records was included in the analysis. Conversion of results obtained by particle counting, expressed as millions of particles per cubic feet (mppcf) of gravimetrically from a filter cassette and expressed as m...
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...
متن کاملNitrate removal from groundwater using electrolytic reduction method
Nitrate (NO3) contamination of groundwater is a major concern throughout intensive agricultural areas. In the present laboratory scale study, an electrolytic reduction method employing copper cathode and insoluble triple mixed oxide anode was studied for the denitrification of groundwater in a divided cell. Influence of process parameters such as pH, current density and time were studied and th...
