Chorisia speciosa Extract Induces Systemic Resistance against Tomato Root Rot Disease Caused by Rhizoctonia solani

Chemical pesticides and fungicides are used extensively, negatively affecting people’s health the environment. Reducing synthetic increasing efficiency of sustainable food production using plant extracts as natural chemicals is a win–win. Here, we first describe evaluate an ethanolic extract Chorisia speciosa for its protective curative activities against Rhizoctonia solani in greenhouse-grown tomato plants. The results showed that mycelial growth R. was completely suppressed vitro by C. (10 µg/mL). Twenty days after fungal inoculation, demonstrated µg/mL) vivo significantly improved shoot root parameters treatments. Further, treatments decreased disease index 26.67% 53.33%, respectively. speciosa-treated plants increased antioxidant enzyme (PPO, CAT, SOD) up-regulated PR-1, PR-2,PR-3, PAL, CHS expression levels compared to untreated According HPLC examination, most prevalent phenolic acids or flavonoid components quantities (µg/mL) noticed were 7-OH-flavone (10.36), kaempferol (9.23), p-coumaric acid (8.65), ferulic (8.14), caffeic (7.59), gallic (6.33), iso-ferulic (5.71). Our findings demonstrate can assist combating infestation. Therefore, data imply extract, renewable product, could be adopted long-term approach regulating fungus.
