Effect Of Carbon disulphide, Acrylonitrile And Formaldehyde On Egyptian Paddy Grain-Borne Fungi

Abstract

Fumigation, with various doses of carbon disulphide, acrylonitrile and formaldehyde for 8, 16 and 32 hours, of paddy grains indicate that formaldehyde was more toxic to the fungi than carbon disulphide and acrylonitrile. The most tolerant fungi to the three fumigants were AIternaria alternata and Cladosporium cladospor-ioides, in addition to Epicoccum purpurascens to acrylonitrile, and Peaicillium chrysogenum and E. purpurascens to carbon disulphide. But, all the preceding fungi were eradicated at the highest doses of the three fumigants. Formaldehyde and acrylonitrile seriously reduced the germinability of paddy grains, whereas carbon disulphide was less deleterious
