FUNGICIDAL EFFECTS OF HOMEOPATHIC DRUGS IN THE CONTROL OF ROOT ROT FUNGI AND GROWTH OF LEGUMINOUS AND NON LEGUMINOUS CROPS
Asma Hanif and Shahnaz Dawar 2015
ABSTRACT
Homeopathic drugs due to fungicidal potential are used as substitute technique in reducing the incidence of root rot fungi like Rhizoctonia solani, Fusarium spp and Macrophomina phaseolina. Homeopathic drugs such as Arnica montana and Thuja occidentalis with 100, 75 and 50% v/v concentrations were used to investigate growth parameters and for the control of root rot fungi by using soil drenching and seed treatment methods. Results showed that pure homeopathic concentration (100% v/v) not only enhanced plant growth but also completely inhibited the incidence of root rot fungi followed by 75 and 50% v/v concentrations which also improved plant growth and showed maximum inhibition in root colonization of both leguminous viz., mung (Vigna radiata (L.) R.Wilczek) and mash (Vigna mungo (L.) Hepper) and non-leguminous viz., sunflower (Helianthus annuus L.) and okra (Abelmoschus esculentus (L.) Moench) plants.

RESULTS
Seeds and soil treated with homeopathic drugs showed 100% germination of mung (Vigna radiata (L.) R. Wilzeck), mash (Vigna mungo (L.) Hepper), sunflower (Helianthus annuus L.) and okra (Abelmoschus esculentus (L.) Moench) plants. In mash bean, significant (P≤0.001) enhancement in growth parameters was observed at 100, 75 and 50% v/v concentrations respectively by A. monatana and T. occidentalis. Pure concentration (100% v/v) of both drugs showed complete inhibition of root rot fungi by both methods. Thuja @ 75% v/v (P≤0.001) showed complete inhibition of R. solani and M. phaseolina in both methods (Fig.1). There was significant increased(P≤0.001) in growth parameters of mung bean and complete inhibition of root infecting fungi observed when Arnica and Thuja used @ 100% v/v(P≤0.001) respectively treated by both methods. In seed method, Thuja @ 75% v/v (P≤0.001) suppressed R. solani colonization (Fig.2). In non-leguminous plants viz., sunflower and okra both showed significant growth (P≤0.001) and complete inhibition of root rot fungi was observed by pure concentrations when both drugs applied by using both methods. In soil drenching method, colonization of R. solani was completely inhibited when soil was treated with Arnica and Thuja @ 75 and 50% (P≤0.001) v/v concentrations respectively ...
... Observations showed that A. montana and T. occidentalis (30Q) when used in 100% v/v concentration not only
improved plant growth but showed complete inhibition of root rot fungi like R. solani, M. phaseolina and Fusarium
spp. followed by 75 and 50% v/v concentrations which also enhanced plant growth and showed maximum inhibition
in both leguminous and non-leguminous plants by using seed treatment and soil drenching methods, respectively.

FUNGICIDAL POTENTIAL OF HOMEOPATHIC PELLETS IN THE INHIBITION OF ROOT ROT FUNGI AND FOR PROMOTION OF CROP PLANTS PRODUCTIVITY
Hanif A, Dawar S, Tariq M and Imtiaz F (2015)
ABSTRACT: Root rot pathogens cause heavy economic damages in agricultural field. The aim of this research is to evaluate the fungicidal efficacy of potentised homeopathic pellets (30C) namely Arnica montana and Thuja occidentalis on germination, growth, yield of crop plants and root rot fungi particularly Fusarium spp, Rhizoctonia solani and Macrophomina phaseolina. Homeopathic pellets were found to be effective in inhibiting the mycelial growth of test fungi in vitro experiment. Whereas, investigation in vivo field experiment showed that A. montana and T. occidentalis pellets @ 75% v/w concentration (prepared from 30C) remarkably control the pathogenic fungi and significantly enhanced the growth parameter and yield of crop plants followed by 50% v/w concentration (prepared from 30C) as compared to control. Experiments have shown positive effect in reducing the intensity of disease caused by root rot pathogen and improve the growth of crop plants.
