Abstract
Dipping the tops of plants, prior to planting, in a 5 per cent oil-based emulsion formulation of DDT has given good control of Hylobius but does not control Hylastes and may involve damage due to phytotoxicity in some circumstances. Experimentation with newly introduced water-based formulations of DDT and BHC confirmed earlier findings that there are few significant differences between possible materials. The need to dip whole plants in order to control Hylastes , with minimum risk of phytotoxicity, has led to the use of 1.6 per cent water-based BHC on a field trial scale with promising results.Keywords
