Control Fig Mosaic Virus By plant extracts with salicylic acid

Abstract

Many attempts have been made to reduce or limit the economic damage caused by the fig mosaic virus to the growth of fig trees and their production from the fruits, in this study the disease in fig seedlings was controlled by aqueous extracts of licorice roots and garlic cloves, salicylic acid. experiments in the greenhouse showed that salicylic acid spraying treatments and aqueous extracts of licorice root and garlic plant cloves individually and twice on intact fig seedlings infected with the fig mosaic virus had a significant effect in reducing the severity of the virus and increasing plant growth indicators such as number of leaves, plant height, leaf content of chlorophyll and elements Nitrogen and phosphorous, and the interaction treatment between licorice extract and garlic cloves extract outperformed in achieving the lowest rate of infection severity, which reached 26.45%, compared to the control treatment, which amounted to 90.36%.

Transcriptomic Analysis Reveals Candidate Genes in Response to Sorghum Mosaic Virus and Salicylic Acid in Sugarcane

“…Exogenous application of SA could significantly reduce the infection effect of the virus and effectively increase plant height and leaf number [ 22 ]. Similar findings were reported by Zagier et al [ 23 ] to control fig mosaic virus by exogenous application of SA. Based on qPCR results, low viral populations were observed at different time points (except for 28 d in ROC22) in response to post-SA application in both cultivars as compared to the control in this study.…”
