Foliar spray and micro-injection of plant growth-promoting rhizobacterial species,viz. Pseudomonas fluorescens andP. aeruginosa on chickpea induced synthesis of phenylalanine ammonia-lyase (PAL) when tested againstSclerotinia sclerotiorum. Induction of PAL was also associated with increased synthesis of phenolic compounds such as tannic, gallic, caffeic,(More)
The isoquinoline alkaloids hunnemanine and norsanguinarine have been isolated from methanolic extract of the whole plant of Eschscholtzia californica. These two alkaloids were checked for their antifungal activity against phytopathogenic fungi Alternaria melongenae, A. brassicola, A. brassicae, Curvularia lunata, C. maculans, Helminthosporium pennisetti, H.(More)
The indole alkaloid venenatine exhibited antifungal activity against some plant pathogenic and saprophytic fungi. Venenatine in an aqueous acetic acid solution inhibited spore germination of all the 10 tested fungi;Fusarium udum, Alternaria brassicicola, Ustilago cynodontis andAspergillus flavus showed an especially high sensitivity towards this compound,(More)
Qualitative and quantitative estimation of phenolic compounds was done through high performance liquid chromatography (HPLC) in different parts of pea (Pisum sativum) after treatment with two plant growth-promoting rhizobacteria (PGPR), viz., Pseudomonas fluorescens (strain Pf4) and Pseudomonas aeruginosa (referred to here as Pag) and infection by Erysiphe(More)
The alkaloid fuyuziphine was isolated from the whole plant of Fumaria indica. It had inhibitive effect against spore germination of some plant pathogenic fungi (Collectotrichum sp., C. gloeosporioides, C. falcatum, Curvularia maculans, C. lunata, Erysiphe cichoracearum, Helminthosporium pennisetti, Oidium erysiphoides, Ustilago cynodontis, Alternaria(More)
Berberine iodide, an isoquinoline alkaloid was isolated fromFumaria indica and its efficacy was tested against spore germination of some plant parasitic as well as saprophytic fungi. The alkaloid significantly curbed spore germination ofCurvularia lunata, Erysiphe cichoracearum, E. pisi, Fusarium udum andPenicillium species. Complete inhibition (100%) of(More)
Berberine and santonin were isolated from rhizomes ofBerberis aristata and unexpanded flower buds ofArtemisia maritima, respectively. Efficacy of these two chemicals individually as well as of their mixtures, was tested against spore germination of some saprophytic and obligate fungi. While berberine individually was effective against most of the(More)
A plant quaternary alkaloid Δ3-alstovenine inhibited the spore germination of most of the fungi tested at concentration of 250–1000 mg/L. Saprophytic and biotrophic fungi were equally sensitive to the alkaloid.Cercospora sp. was the most sensitive as 100% inhibition of spore germination was observed at 250 mg/L.Alternaria species,Curvularia species(More)
3-(2-Pyridyl)-3-iminoisatin, 1-piperidinomethyl-3-(2-pyridyl)-3-iminoisatin, and 1-acetyl-3-(2-pyridyl)-3-iminoisatin affect spore germination ofAlternaria alternata, A. carthemi, Curvularia lunata, Fusarium oxysporum f.sp.cieri andF. udum and influence the development of powdery mildew (Erysiphe pisi) on pea under glasshouse condition as well as conidial(More)
