Comparison of sampling procedures for estimating botrytis bunch rot incidence in New Zealand vineyards

Botrytis Bunch Rot: A Disease Requiring Integrated Control

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...

Effects of Bunch Rot (Botrytis cinerea) and Powdery Mildew (Erysiphe necator) Fungal Diseases on Wine Aroma

This study aimed to characterize the effects of bunch rot and powdery mildew on the primary quality parameter of wine, the aroma. The influence of these fungal diseases was studied by comparative Aroma Extract Dilution Analyses (AEDA) and sensory tests. The effect of bunch rot was investigated on three grape varieties, namely White Riesling, Red Riesling and Gewürztraminer and that of powdery m...

Uniformity of Strawberry Yield and Incidence of Botrytis Fruit Rot in an Annual Production System

Quantification of the Changes in Potent Wine Odorants as Induced by Bunch Rot (Botrytis cinerea) and Powdery Mildew (Erysiphe necator)

Fungal infections are detrimental for viticulture since they may reduce harvest yield and wine quality. This study aimed to characterize the effects of bunch rot and powdery mildew on wine aroma by quantification of representative aroma compounds using Stable Isotope Dilution Analysis (SIDA). For this purpose, samples affected to a high degree by each fungus were compared with a healthy sample ...
