PROTECTION TUBER QUALITY

摘要

Seed treatments help protect your investment, while laying a solid foundation for the remainder of the growing season. Willie Kirk, plant pathologist at Michigan State University, said growers in Michigan must be vigilant against three main diseases:seedborne late blight, rhizoctonia and fusarium seed-piece decay. "What we recommend are products with mancozeb components," Kirk said. "Maxim 4FS, followed by a mancozeb dust treatment. We don't like dust treatments from a health standpoint, but they enhance suberization and prevent seed-to-seed spread of disease at cutting." The Maxim 4FS treats silver scurf, rhizoctonia and fusarium immediately, followed by some treatment containing mancozeb to prevent the transmission of late blight.
