Enhanced Systemic Resistance and Yield against Puccinia triticina Eriks in Wheat through Botanicals under In-vivo condition; An Eco-Friendly Approach

In present study four types of botanical extracts including neem (Azadirachta indica L.), safeda (Eucalyptus cameldulensis Dehnh.), rosemary (Rosmarinus officinalis Spenn.) and ajwain (Trachyspermum-ammi L.) were selected pre-inoculated on susceptible wheat cultivar “Morocco” to evaluate their effect oxidative enzyme activity, chlorophyll contents, phenol contents yield components against Puccinia triticina Eriks under In-vivo conditions during 2018/2019 growing seasons. Coefficient infection (ACI) for all botanicals ranging between 6.50-16.50 as compared control (ACI= 78.00) reflect the significant response in reducing leaf rust. Ajwain was most effective, its efficiency reached 91.66%, similar fungicide spotless 12.5 WP (93.20%) followed by (85.25%), (82.00%) (78.84%). Moreover, tested significantly increased components. Similarly, biochemical analysis revealed that enzymes activities (POX PPO) treated plants increased. We conclude pre-application is a promising approach management rust wheat.
