Bunch Rot

Botrytis bunch rot (botrytis) can reduce grape yield and wine quality Standardised assessment methods are needed to allow greater precision in wine making and to allow the use of disease management decision support models in grape production This study developed a botrytis disease assessment key to assist the accuracy of visual disease assessment Associated computer training software designed to improve the accuracy of disease assessments was also developed and tested The mean absolute error in estimates of percentage botrytis severity was significantly (P

Bunch Rot

Nitrogen is an important macronutrient for grapevines influencing a number of metabolic pathways and plant structures This review provides a summary of some direct and indirect effects of nitrogen fertilisation on bunch rot incidence in the field Direct changes due to increased nitrogen nutrition include greater thickness of the wax on berry surfaces and increased concentrations of the biochemical defence compounds produced in them Indirect changes that result from increased nitrogen include development of tighter bunches and denser canopies As integrated management systems become more complex a better understanding of different components such as nitrogen nutrition is required to allow vineyard managers to make informed decisions on how potential changes to current practices may influence disease and berry quality parameters
