Abstract
Chickpea (Cicer arietinum L.) is subject to stand injury and yield loss due to several diseases. Rizhoctonia solani found to be pathogenic to Chickpea causing damping-off and root-rot. Chemicals are effective in controlling these diseases but, these chemicals are expensive and not friendly to the environment. There are great efforts to reduce environmental pollution by reducing the dependence on agrochemicals to control plant diseases. Plant extracts and resistant chickpea varieties are used between many other means to control some diseases. Some plant extracts such as Rosemary(Rosemerinus officinalis) leaves and Colocynth (Citrullus colocynthis) fruits inhibited mycelial growth of Rhizoctonia solani on PDAmedium. The results from this study demonstrated that both plant extracts were effective against Rhizoctonia.solani growth. In pots, all tested plant extracts significantly decreased damping-off, and increased healthy plants with corresponding increases of plant height and seed yield weight. Reducing sugar decreased whereas, the level of phenols increased in infected plants. In addition to performance of pretreated plants are similar to uninfected control plants, it might be due extracts of both Rosemary and Colocynths which have a role in plants react to pathogen attack by activating an elaborate defense mechanisms. However, the immediate impact of this research is promising in that it provides a safer alternative than synthetic fungicides. Especially, Rosemary extract is often used in food preparations for human consumption; thus there should be a major concern over toxicity.
