Viticulture. As a part of its Initiative Cowara, Grand Chelem has adopted viticultural practices whereby the use of glyphosate and paraquat is dispensed with in favour of organic alternatives. Canopy management is aimed at reducing the need for the spraying of fungicides to a bare minimum. In a first for the Margaret River region, the house is exploring the eradication by organic means of the vine snout weevil (phlyctinus callosus) introduced to Australia from South Africa.
