Wilt is an important disease of tomato crop causing significant reduction in yield. In present study, the pathogenic fungus was isolated from infected plant and identified based on morphological and cultural characters as Fusarium oxysporum f.sp.lycopersici whose pathogenicity was confirmed by Koch’s postulate on tomato seedling. In vitro evaluation of extracts of 20 plant species was done by p...

Using HPLC on a partisil column (5 nm) it was possible to separate two reaction products from an enzyme incubation of dimethylallylpyrophosphate and 3,6a,9-trihydtoxypterocarpan with a particulate fraction from elicitor-treated soybean cotyledons (Harosoy 63) or soybean cell cultures. These two products were identified by MS and !H-NMR analysis as 2and 4-dimethylallyltrihydroxypterocarpan. Both...

The fungitoxic properties of vapours of essential oil extracted from Cinnamon (Cinnamomum zeylanicum Breyn) bark have been investigated against five species of Aspergillus viz. A. flavus Link, A. fumigatus Fresenius, A. nidulans (Eidam) Wingate, A. niger van Tiegham and A. terreus Thom, causing biodeterioration of paper manuscripts in Gorakhpur. The fungitoxicity was determined in vitro as mini...

the essential oil extracted from the epicarp of citrus sinensis exhibited absolute fungitoxicity against soybean’s fungus as alternaria alternate, aspergillus niger, cercospora kikuchii, chaetomium spp., cladosporium cladosporioides, curvularia lunata, fusarium roseum, macrophomina phaseolina, penicillium italicum, phomopsisspp. rhizoctonia solani, and sclerotium rolfsii. it is very difficult t...

A series of diand tributyltin(IV) carboxylate compounds prepared by reacting the dibutyltin(IV) dichloride and tributyltin(IV) chloride respectively via the organotin(IV) oxide with the respective carboxylic acids have been tested for antifungal activity against Fusarium oxysporum and Aspergillus niger in potatoes dextrose agar. The compounds synthesized were mainly characterized with IR and UV...

Invitro antimycotic effect of the coconut, mustard, groundnut & soyabeen oils and the seeds of trigonella, ajwoin, mustard and garlic bulbs were mixed in the above oil samples to determine their effect on the spore germination of five pathogenic fungi i.e., Aspergillus niger, A.flavus, Absidia corymbifera, Penicilium nigricans and Candida albicans, isolated from otitic fungal infection of exter...
