Potato tuber moth (Gnorimoschema operculella (Zell.)) investigations in southern Queensland

May, A. W. S. (1952) Potato tuber moth (Gnorimoschema operculella (Zell.)) investigations in southern Queensland. Queensland Journal of Agricultural Science, 9 (2). pp. 142-168.



Three (sometimes two) applications of 1 lb DDT per acre at fortnightly intervals prevented infestation of tops during most of the growing period of the spring-planted crop and reduced the likelihood of tuber infestation. DDT was more effective as a spray than a dust; sprays produced increases of up to 17% in number and 43% in weight of table quality tubers. The proper integration of DDT spraying and hilling is essential for Gnorimoschema control, as each fulfils a separate but complementary role in ensuring the maximum production of sound tubers.
