Efficacy of plant extracts and effect of seed soaking duration on treatment of sorghum seed naturally infected by Colletotrichum graminicola and Phoma sorghina

The study was undertaken to evaluate the effectiveness of the aqueous extracts ofBalanites aegyptiaca (L.) Del., Cymbopogon citratus D. C. Stapf, Cassia occidentalis L. and Portulaca oleracea L. different durations of extracts maceration (6, 12, 24 and 48 h) and different durations of soaking seed i...

Description
Summary:The study was undertaken to evaluate the effectiveness of the aqueous extracts ofBalanites aegyptiaca (L.) Del., Cymbopogon citratus D. C. Stapf, Cassia occidentalis L. and Portulaca oleracea L. different durations of extracts maceration (6, 12, 24 and 48 h) and different durations of soaking seed in plant extracts (6, 12 and 24 h). All the plant extracts tested significantly reduced the infection rate by C. graminicola and P. sorghina except for the extract of C.occidentalis which was not efficient against P. sorghina. Extract of C. citratus and P. oleracea were more efficient on the reduction of the infection rate by C.graminicola. Those of B. aegyptiaca and C. citratus were the most efficient in reducing infection by P. sorghina. Long period of soaking and macerate were favourable in increasing of the antifungal efficiency of the extract.
