A note on the effect of vinekilling on specific gravity of Kennebec and Sebago tubers

Summary

Spraying Kennebec and Sebago potatoes with a chemical vinekiller so that the vines were killed in approximately 10 days did not result in the tubers having a higher specific gravity than those from plants killed instantly (by digging). In the case of late-maturing potatoes, vinekilling in time to allow the skins of the tubers to “set” by harvest is the most important consideration.
