inhibitory effect of ethanol extract of water cress (nasturtium officinale l.) on the growth of fusarium solani, the causal agent of potato dry rot, in vitro
Authors
abstract
biological control of plant pathogens with the aim of reducing the harmful effects of pesticides on human health threats, environmental pollution, eliminating non-target organisms and the emergence of resistant pathogens is a priority. in this regard, the use of antimicrobial potential of plant metabolites, have been discussed in recent years. in this study the effects of ethanol extract of water cress (nasturtium officinale l.) on the growth of fusarium solani, the causal agent of potato dry rot, in vitro were investigated. the experiment was performed in the frame of a randomized complete block design with six treatments and four replicates. the treatments were 300, 400, 500 and 600 mg/ml of extract of nasturtium officinale l. and a fungicide and were as controls. for this purpose, the plates of (pda) medium were inoculated with the suspension spore of fusarium solani (1×106 spore/ml) and the disk diffusion method was used to evaluate the effect of the extracts on the growth of the fungus. the results indicated that all concentrations of the extract used, were effective in controlling the growth of the fungus and the effect was close dependent. these rents suggest that the extract of nasturtium officinale l. can be used to control in the growth of fusarium solani. however, recommended further investigations on control of the fungus in potato are needed.
