Hazelnut growers target pathogens, pests
Mateusz Perkowski writes: Heavily shaded hazelnut orchards may discourage salmonella from lingering on the ground, but the conclusions for growers remain uncertain, according to an orchard researcher.
Ground temperatures in heavily shaded hazelnut orchards appear to fall below the temperature range in which salmonella thrives, compared to orchards with less shade cover, said Bruce Lampinen, a tree nut specialist with the University of California Cooperative Extension.
The results in Oregon hazelnut orchards were greatly different than in California almond and walnut orchards, where heavy shade cover seems to improve conditions for salmonella, he said.
