It seems an end is in site for South Africa's other big virus problem. By 2013 - assuming the Mayan calender does not come to pass - some producers including Stellenzicht will be planting leafroll virus resistant vines. However this has not occured through technology (but dont tell Thabo & Manto) but rather through good old fashioned foot slog and natural selection (no beetroot juice involved either).
By observing infected vineyards over two seasons, consulting viticulturalist Eben Archer identified naturally resistant vines in heavily infected blocks and has propagated these for replanting of vineyards. Although these came up clean in local tests - and in the USA and France - Archer will only let time reveal if he has been successful.
