essential oil extracted from the leaves of lemon verbena, lippia citriodora kunth (verbenaceae) was tested for fumigant toxicity in the laboratory against two stored-product insects tribolium confusum jacquelin du val and callosobruchus maculatus (f.). the chemical composition of the isolated oil was examined by gc-ms. the major compounds were citral (11.3%), limonene (10.6%), neral (7.9%), 4-p...

certain compounds of plants such as essential oils, with insecticidal properties have been considered as alternatives to chemical pesticides for pest control. this study reports the fumigant toxicity of citrus reticulata blanco (rutaceae) peel essential oils against stored-product insect pest, red flour beetle, tribolium castaneum herbst (tenebrionidae) adults. experiment was carried out at 27 ...

The potent greenhouse gas sulfuryl fluoride (SO2F2) is increasingly used as a fumigant, replacing methyl bromide, whose structural and soil fumigation uses have been phased out under the Montreal Protocol. We use measurements on archived air samples in situ observations from Advanced Global Atmospheric Gases Experiment (AGAGE) box model of global atmosphere to show increase SO2F2 mole fraction ...

The fumigant 1,3-dichloropropene (1,3-D) has been identified as a partial replacement for methyl bromide (CH3Br) in soil fumigation. 1,3-Dichloropropene is formulated for soil fumigation as Telone II (Dow AgroSciences, Indianapolis, IN) for shank application and as an emulsifiable concentrate (EC) (Telone EC or InLine; Dow AgroSciences) for drip application. This study investigated the effect o...
