Grape sour (bunch) rot is a polymicrobial disease of vineyards that causes millions of dollars in lost revenue per year due to decreased quality of grapes and resultant wine. The disease is associated with damaged berries infected with a community of acetic acid bacteria, yeasts, and filamentous fungi that results in rotting berries with high amounts of undesirable volatile acidity. Many insect...

The efficacy of an edible chitosan coating (CHI; 4 mg/mL) and Origanum vulgare L. essential oil (OVEO; 1.25 μL/mL) for maintaining the quality of cherry tomato fruit during storage at room (25°C; 12 days) and cold (12°C; 24 days) temperatures was assessed. CHI and OVEO in combination showed in vitro fungicidal effects against R. stolonifer and Aspergillus niger. CHI-OVEO coating reduced the inc...

A large collection of Botryosphaeriaceae isolates obtained from fruit and forest trees with fruit rot, canker and dieback disease symptoms in northern provinces of the country were examined in this study. Based on morphology and sequence data (ITS and EF1-α), two species, Diplodia mutila and Spencermartinsia viticola are illustrated and described as new records for Iran mycobiota. Furthermore, ...

The purpose of this study was to determine the fine-scale genetic structure of populations of the brown rot pathogen Monilinia fructicola within individual peach tree canopies to better understand within-tree plant pathogen diversity and to complement previous work on spatiotemporal development of brown rot disease at the canopy level. Across 3 years in a total of six trees, we monitored diseas...

This study was conducted to determine the antifungal activity of the metabolites from Streptomyces sp. 3-10, and to purify and identify the metabolites. Meanwhile, the taxonomic status of strain 3-10 was re-evaluated. The cultural filtrates of strain 3-10 in potato dextrose broth were extracted with ethyl acetate. The resulting crude extract at 1 and 5 μg/ml inhibited growth of 22 species in 18...

Botrytis bunch rot (BBR), caused by the fungus Botrytis cinerea, causes damage to ripening grape clusters throughout the temperate regions of the world where pre-harvest rains occur. Although pure Botrytis infections free of secondary contaminants can sometimes produce the so-called "noble rot" integral to the production of certain prized dessert wines, a far more common result is a disease tha...

The antifungal potential of aqueous leaf and fruit extracts of Capsicum frutescens against four major fungal strains associated with groundnut storage was evaluated. These seed-borne fungi, namely Aspergillus flavus, A. niger, Penicillium sp. and Rhizopus sp. were isolated by standard agar plate method and identified by macroscopic and microscopic features. The minimum inhibitory concentrations...
