Abstract

A study was conducted duriog 1992-93 at Bangalore on the bioefficacy of chlorothalonil for controlling leaf
blight of geranium (Pelargonium graveolens (L.) Herit.) caused by Colletotrichum gloeosporiodes Penz. the
chlorothalonil sprayed plots effectively reduced the disease intensity and gave on an average 242 and 192% greater
yields of herbage and essential oil, respectively, compared with the unsprayed plots and it was at par with captafol sprayed
plots in both the years. Chlorothalonil though found effective against Collelolrichum gloeosporiodes was not economical
as captafol because of its higher cost.
