Cultural means of controlling potato tuber moth (Phthorimaea operculella Zell) and improvement of potato yield and quality in the Sudan



Cultural means of controlling potato tuber moth (Phthorimaea operculella Zell) and improvement of potato yield and quality in the Sudan



Acta Horticulturae (218): 281-287



Damage by Phthorimaea operculella increased steadily on potatoes sown successively on 15 November (the optimum sowing date) to 5 and 25 December in Sudan; yields of marketable tubers declined correspondingly. Increasing sowing depth from 1 to 3 inches reduced damage and increased yield, but the application of nitrogen and re-ridging during tuber formation were not effective. Delay in harvesting increased infestation and reduced yield.
