Abstract: Commercially available chemical fumigants have been found to be the most common and effective in stored grain pest management as they show optimum effect with even low doses. The present paper aims to compare efficacy of two commonly used chemical fumigants such as Parad and Grain Phos with plant leaves like Aegle mermelos, Azadirachta indica, Cymbopogon citrates, Ocimum sanctum, O. basilicum and Murraya koenigii aginst Rice Weevil, S. oryzae. The fumigants Parad and Grainphos were selected for the study and were found to be effective even at lower concentration in both the Triticum cultivars Lokwan and Sharbati. In the lower concentration of Parad, weight loss recorded was 0.23 and 0.22% respectively, it was no loss recorded at higher concentration in both varieties. While in case of Grainphos, at lower concentration 0.21% and 0.19% weight loss were recorded in Lokwan and Sharbati respectively whereas in higher concentration there was no loss in both the cultivars. The effects of these chemical fumigants were compared with the effects of Azadirichta indica and other five plant leaves and it was found to be at par in both Lokwan and Sharbati cultivars respectively.
