Abstract
Among different parts of Coleus spp., dried leaf powder (25 g/l of water) was found most effective in reducing the fresh weight and chlorophyll content of E. crassipes and showed 100 reduction on 9 and 6 days after treatment, respectively. Combination of 3/4th of dried leaf powder (18.75 g/l) + 1/4th of dried whole plant powder (6.25 g/l) was also found effective next to 25 g/l dried leaf power. Dried stem powder (25 g/l) showed minimum reduction in fresh weight and chlorophyll content.
