Jan Peeters was presented with the annual Fruit Culture Award by the Worshipful Company of Fruiterers at the National Fruit Show.
Peeters' business, Fruit Consult, advises more than 600 grower clients in 14 countries on orchard establishment and management.
"Peeters has been particularly involved with the OrchardWorld supplier and Sainsbury's concept demonstration orchards and the associated grower focus group," said Worshipful Company of Fruiterers master Sandys Dawes.
The supermarket's orchard was launched in 2007 to explore organic growing techniques.
"Hundreds of hectares of intensive orchards have been planted under his influence, with most achieving a 100 per cent increase in yield and improved grade of supermarket-quality fruit," Dawes said.
