Spray deposition and control of botrytis cinerea on grape leaves and bunches : part 2 (wine grapes)

Brink, J. C.; Calitz, F. J.; Fourie, P. H. (South African Society for Enology and Viticulture, 2016)

Poor control of fruit and foliar diseases in vineyards is often attributed to insufficient spray deposition of susceptible tissue. To optimise spray deposition, a deposition assessment protocol using fluorometry, photo ...
Spray deposition and control of botrytis cinerea on grape leaves and bunches : part 1 (table grapes)

Brink, J. C.; Calitz, F. J.; Fourie, P. H. (South African Society for Enology and Viticulture, 2016)

Insufficient quantity but also quality of spray deposition on susceptible grapevine tissue (i.e. target sites) and favourable conditions for pathogens could lead to control failure during high disease pressure situations. To ...
An integrated strategy for the proactive management of grapevine trunk disease pathogen infections in grapevine nurseries

Halleen, F.; Fourie, P. H. (South African Society for Enology and Viticulture, 2016)

The aim of this study was to compare 11 treatment regimes (TR) in grapevine nurseries in order to eradicate trunk pathogens. Grapevine propagation material was subjected to treatments before cold storage, before and after ...
