Efficiencies of select vector repellents during composting of Municipal Solid Waste
Presently, most preferred mode of treatment of Municipal Solid Wastes (MSW) is composting. However, this may lead to health hazard because of the potential presence of pathogens, and vector borne insects, rodents etc., in the compost. Field studies were undertaken towards use of Folidol (organophosphate) and Celrich (biopesticide) as repellents of vectors while composting of MSW. At 0.05 kg m−2 Folidol caused significant reduction of fly within ninth day. Celrich, being produced from organic solid wastes, was observed to be effective fly repellent at 0.5 kg m−2. Considering ecological aspects and prospects of better fertilising potential of the end products of composting, Celrich can be a better choice as vector repellents.
