The adverse effect of pesticides used for controlling pests and the diseases caused by them is extensively rising. To overcome this harmful environmental impact, alternative methods are being studied and developed. Out of many possible methods, one effective method is to use plant extracts which embodies natural substances having antifungal properties. In an attempt towards enhancement of sustainable antifungal approach, four different concentrations of four plant extracts Citrus limon, Azadirachta indica, Ocimum gratissimum and Acalypha indica, were tested for their antifungal activity against Rhizoctonia solani, which is a serious threat for plants, and is responsible for considerable crop and yield losses. The aim of this study is to minimize yield losses and to regain the attention of formers towards exploiting natural resources for diseases control. From the results, it can be concluded that different concentrations of plant extracts have caused substantial inhibition in the mycelial growth of R. solani. The leaf extract of Ocimum gratissimum was highly effective in inhibiting mycelial growth, at the concentration of 500mg/ml of extract followed by Citrus limon, Azadirachta indica, and Acalypha indica. These plants might have potential for the development of natural fungicide for the management of diseases caused by fungal pathogens. Also, fungicides developed from these botanical extracts can prove to be highly effective for the management of plant diseases and would be simply obtainable, nonpolluting, biodegradable and economical.
