Control of light-brown apple moth

Abstract

Alternatives to lead arsenate for the control of light-brown apple moth, Austrotortrix postvittana (Walk.), were tested in three spray trials in apple orchards in the Stanthorpe district during the 1954-55 season. Programmes incorporating DDD were generally superior to all others, and at the same time avoided the foliage damage and spray residue problems associated with the use of lead arsenate. Two sprays of DDD 0.1 per cent., one applied in late November and the other in late January, are basic for the control of light-brown apple moth.
