The effects of the dormancy releasing chemicals, Rindite and bromoethane, on subsequent tuber response to dry rot were evaluated. Seed tubers of the cultivars Sebago and Acadia Russet were treated with Rindite or bromoethane, and subsequently inoculated with sterile distilled water or spore suspensions ofFusarium sambucinum Fuckel f. 6 Wollenw. After storage for 1 or 11/2 months, tubers were rated for dry rot and dormancy release. Development of seed tuber breakdown byFusarium was not significantly affected by pretreatment with Rindite or bromoethane regardless of any effect on tuber dormancy.
