A groundbreaking biofungicide, developed by UK firm Eden Research, has gained regulatory approval in New Zealand to help fight botrytis in its Sauvignon Blanc.
Due to New Zealand’s damp conditions and fluctuating temperatures, its vines are prone to botrytis, with its popular Sauvignon Blanc variety particularly susceptible to the rot.
However, a solution may now be in sight thanks to a new sustainable biofungicide called Novellus that its makers hope will stem the costly problem. It is estimated that botrytis can cause a financial loss to New Zealand winery owners of up to NZ$5,000 (£2,500) per hectare.
The biofungicide will be rolled out across kiwi vineyards later this year, having previously been actioned in Australia.
Eden’s partner Sipcam Oxon will exclusively distribute Novellus in New Zealand, beginning with the 2023/24 growing season, during the Southern Hemisphere’s summer and early autumn when fungal treatment typically takes place.
Sean Smith, CEO of Eden, said: “We’re proud to offer a sustainable solution to the destructive botrytis disease in New Zealand, a country with challenging grape growing conditions. Having also gained authorisation in Australia, we’re demonstrating Novellus’ versatility and efficacy across different environments. We anticipate promising sales growth and look forward to working with Sipcam.”
