Gardeners' Notes:

Neutral Farmerdill On Feb 19, 2008, Farmerdill from Augusta, GA (Zone 8a) wrote:

From Syngenta/Rogers, which provides this information: "Garrison (formerly GSS3186) features a comprehensive disease package for the Southeast US shipper market. This sweet corn offers strong husk protection, a uniform shipping ear, and excellent tip fill for the Fresh market. Growers looking for a high yielding variety with a strong plant, straight rowing, and a wide area of adaptation should choose Garrison. Its strong disease package includes high resistance to most strains of rust, northern corn leaf blight, and maize dwarf mosaic virus as well as intermediate resistance to Stewart's wilt and Southern corn leaf blight.
