The protection of stored potatoes against the potato tuber moth, Gnorimoschema operculella Zell. Part 1 - Trials in southern Queensland. Part 2 - Trials in northern Queensland.

Abstract

In a southern Queensland trial conducted in 1943-44 it was established that derris dust (1 per cent. rotenone) gave almost complete protection against tuber moth damage and was satisfactory for use on both the seed and table potatoes. Pyridine (5 per cent. dust) was somewhat less effective, and "Hortosan D.P" (an organic mercurial fungicide) was useless for the purpose. Northern Queensland trials in 1946 and 1947 showed derris dust (1 per cent. rotenone), magnesite and DDT (2 per cent. dust) to be effective in protecting stored potatoes, and ferric oxide to be relatively ineffective.
