Crop Protection against Root Rot Fungi by Combined Effect of Homeopathic Drugs and Microbial Antagonists

The objective of this research was to reduce economic losses result from root rot fungi by improving plant growth and control the plant pathogenic fungi to a low and safe level. Seeds of okra, sunflower, mung bean and mash bean treated with homeopathic drugs such as Arnica montana and Thuja occidentalis @ 50 and 75% v/v concentrations (prepared from 30C) along with microbial antagonists namely, Trichoderma harzianum, Paecilomyces variotii, Bacillus subtilus and Rhizobium meliloti drenched in soil which enhanced the plant weight and height but also reduced the Fusarium spp, Rhizoctonia solani and Macrophomina phaseolina colonization as compared to alone treatments. Highest number of nodules was observed on mash bean and mung bean seeds when treated with 75% v/v concentrations by both homeopathic drugs and soil were drenched with R. meliloti. Off the microbial antagonists used, T. harzianum together with treated seeds @ 75% v/v concentrations by both drugs showed better plant productivity and completely suppressed root rot fungi of test plants.
