Phytochemical Analysis and Antifungal Efficacy of Rhizome Extracts of various plants against Fusarium Wilt and Root Rot of Tomato

Abstract

To cite this paper: Chohan, S. and R. Perveen, 2015. Phytochemical analysis and antifungal efficacy of rhizome extracts of various plants against fusarium wilt and root rot of tomato. lycopersici, whereas, least inhibition was observed against F. solani. Correspondingly, conidial germination of test fungi was almost completely reduced by A. sativum extract. Phytochemical screening of crude extract revealed the presence of flavonoids, terpenes, saponins, whereas, A. sativum was also found rich in steroids, tannins, glycosides and coumarins. Tannins were not detected in C. longa. Total phenol contents (TPC) were present in highest quantity ((54.24GAEmg/g) in A. sativum followed by Z. officinale (29.80GAEmg/g), whereas, rhizomes of C. longa contained lowest TPC (25.45GAEmg/g). It was concluded that rhizome extracts of A. sativum possesses sufficient antifungal activity under controlled conditions to warrant a further investigation under field conditions.

Management of Fusarium Wilt of Castor (Ricinus communis L.) Caused by Fusarium oxysporum f. sp. ricini with Antagonist, Botanical Extract and Pot Experiment

“…2). The present studies are in confirmation with those described by earlier worker Chohan and Perveen (2015) studied the effect of botanicals on Fusarium oxysporum f. sp. lycopersici and reported that out of rhizomes extracts tested, Turmeric (Curcuma longa L.) extract was found most inhibitory to Fusarium oxysporum f. sp.…”

Effects of arbuscular mycorrhizal fungi and plant growth-promoting rhizobacteria on growth and reactive oxygen metabolism of tomato fruits under low saline conditions

“…In recent years, extensive utilization of chemical fertilizer has led to increasing land salinization and agricultural pollution (Mokhtar et al, 2020), including vegetables such as tomatoes (Solanum lycopersicum). Tomato is one of the most nutritious fruits and vegetables consumed worldwide; it is an excellent source of vitamin C, sugar, and natural antioxidants (Chohan and Perveen, 2015). However, salt stress has a deleterious effect on tomato growth, which represses seed germination, reduces the survival rate, and decreases nutrient biomass (Egamberdieva et al, 2019).…”

N-Acetyl-d-glucosamine Inhibition of Hexokinase Results in Downregulation of the Phenylpropanoid Metabolic Pathway and Decreased Resistance to Brown Rot in Peach Fruit

“…Increasing the gene expression of HXK increases the activity of PAL and C4H in Arabidopsis seedlings, and the content of flavonoids. 38 As the main products of phenylpropanoid metabolism, phenolics and flavonoids can inhibit fungal spore germination 39 and mycelial growth, 40 and play an essential role in disease resistance. Therefore, NAG inhibited HXK activity, repressed phenylpropanoid metabolism, and reduced the accumulation of phenols and flavonoids, resulting in the decreased disease resistance in peach fruits.…”
