Blaaspootjies veroorsaak ekonomiese skade in alle Suid-Afrikaanse tafeldruifproduksie-areas.
Volg hierdie vier stappe om tafeldruiwe te beskerm.
Are viruses to blame for the colouring problem in the Crimson Seedless table grape cultivar?
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…
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.
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.
There’s a growing global focus on slowing the rate of climate change. By Lisa Matthews and Chantelle Smit (Confronting Climate Change Initiative) We know what is needed. It’s cuts in greenhouse gas emissions to the point where emissions are no…

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.
INTRODUCTION Margarodes are subterranean scale insect pests that attack plant roots. Of the 10 species known in SA, five attack grapevines while the rest mainly occur on grasses. Margarodes prieskaensis is widespread within the Orange River irrigation area in the…
