Dit is onmoontlik om blaaspootjies uit te wis. Deur Anna Mouton Groot bevolkings is wydverspreid op talle gewasse en natuurlike plantegroei in alle tafeldruifproduksieareas. Die beste strategie is om die wingerd tydens kritieke stadiums so goed moontlik te beskerm. Produsente…
Wat kan die vrugtebedryf leer by akkerbou? Dr Johann Strauss deel sy insigte oor bewaringslandbou en die voordele wat volhoubare praktyke vir landbou inhou.
Breeders and researchers can now access published grapevine genetics and omics information through a single integrated platform. By Anna Mouton Omics is a catchword for the different branches of biology that trace how gene expression culminates in protein synthesis and…
False codling moths damage table grapes and many other crops. Chemical crop protectants are important to false codling moth control but environmentally friendly alternatives must be identified.
Advances in breeding technologies may soon expand our ability to improve cultivar performance.
Na agt jaar se droogte het die Klein Karoo uiteindelik weer goeie reëns gehad. Maar die streek kort meer as een nat winter om te herstel. Deur Anna Mouton Die Klein Karoo loop van wes na oos tussen die Swartberge…

A SATI-funded research project tested disinfectants and fungicides in combination with hot-water treatment to control Petri disease in plant material.
“The pre-harvest component is a critical phase for pathogen establishment,” says Dr Johan Fourie, postharvest pathologist at ExperiCo Agri-Research Solutions. “The source of inoculum is in the vineyard – that’s where the pathogen establishes.”
Fungi are responsible for most postharvest decay. Plant-pathogenic fungi can thrive on all sorts of organic material in the vineyard, producing spores that land on bunches. Growers mitigate the risk of postharvest decay by integrated management practices that include removing organic material, maintaining open canopies, and applying fungicides.
Things move fast during harvest season. Table-grape growers must have reliable information on bunch characteristics for each block to ensure the fruit is prepared and handled optimally. This requires ongoing assessment in each vineyard – a time-consuming and labour-intensive activity.
