Carbonyl sulfide (COS) is a new fumigant which has been a potential alternative to methyl bromide and phosphine in many applications. In this study, we investigated the fungitoxicity of COS towards the pathogen of pear black spot disease Alternaria alternata (Fr.) Keissler (A. alternata). Moreover, proteomic analysis and RT-PCR was performed and our results showed that during the fumigation, th...

Six diorganotin(IV) carboxylates prepared by reacting diorganotin(IV) dichlorides with the respective silver carboxylate have been tested for antifungal activity against Aspergillus. niger, Aspergilluus flavus and Pencillium. citrinum in Sabourand dextrose broth. The compounds generally exhibit greater fungitoxicity than the diorganotin(IV) dichlorides and the carboxylic acids from which they w...

Survival of conidia of eight species of Bipolaris, Curvularia, and Exserohilum in soil was compared to identify the species most suitable for use in experiments to assay fungitoxicity of soils amended with animal wastes and agricultural byproducts. Conidia produced on cellulose-containing substrates were added to soil between porous nylon mesh membranes, incubated for 0–12 weeks, retrieved, and...

In the present investigation, 34 Bacillus thuringiensis (Bt) isolates of different agroclimatic condition were studied for fungitoxic characters and the principle involved for fungitoxicity was identified in most of the cases as exochitinases. The different Bt strains were screened for fungitoxicity and chitin degrading activity employing 4 fungal pathogens. Biochemical assay of the chitinase u...

The antifungal activity of homologous series of 2-alkenoic and 2-bromo alkanoic acids was determined against Aspergillus niger, Trichoderma viride, Myrothecium verrucaria, and Trichophyton mentagrophytes and compared with data on analogous alkanoic and 2-fluoro alkanoic acids. The fungitoxicity of all of the series of compounds was determined by chain length, pH of the medium, and presence or a...

Stemphylium sarcinaeforme (Cav.) Wilt. (formerly Macrosporium sarcinaeforme Cav.) and Monilinia fructicola (Wint.) Honey (formerly Sclerotinia fructicola (Wint.) Rehm.) are two fungi which have been widely used as test organisms for screening fungicides in the laboratory. S. sarcinaeforme is resistant to the toxicity of phenolic and quinonoid compounds (herein referred to as phenols and quinone...
