Fargro managing director Paul Sopp said Serenade ASO was launched last year with an open day, backed up with a website and newsletter to inform growers, agronomists, technical managers and multiples to technical benefits and outcomes.
The Bacillus subtilis-based contact bio-fungicide has approval for bulb, stem and leafy vegetables, herbs, legumes and fruit. It fights Botrytis.
Sopp said two main plus points were no chemical residues and little potential for resistance. Such a wide-ranging off-label approval "has created a lot of opportunity for the product, but a bit of a problem in terms of providing advice and how to use the product," he added.
