Production and extraction of phytotoxins from Colletotrichum dematium FGCC# 20 effective against Parthenium hysterophorus L

The aim of this work was to study the herbicidal potential of Cell free culture filtrate of Colletotrichum dematium FGCC#20 against Parthenium by employing different bioassays i.e. shoot-cut, seedling, detached leaf and seed germination. On solvent extraction of the Cell free culture filtrate, Ethyl acetate extracted fraction showed the presence of phytotoxic moiety.

Occurrence of Anthracnose on Cabbage Caused by Colletotrichum dematium

Anthracnose symptoms on young cabbages were found in cabbage nursery fields in Jangheung area of Korea in 1998. The symptoms developed on seedlings, leaves, and stems of young cabbages(Brassica oleracea var. capitata L.). The casual fungus was identified as Calletotrichum dernatium (Fr.) Grove based on morphological and cultural characteristics. Similar symptoms were observed on the cabbage when artificially inoculated on the plant leaves. The fungus was reisolated from the symptoms of the inoculated plant.
