AbstractI visited the Tweed Valley area to assess the pest status of rhopaea canegrub, diagnose reasons for grower dissatisfaction with present control options, and, with affected growers and technical staff to develop a research, development and extension program aimed at improving management strategies for minimising the impact of these canegrubs.My main findings wereRhopaea canegrub is an economic pest of sugarcane in the Tweed area, mainly on the peat soils, and causes important losses to some of the otherwise most productive growers.The year 1-year life cycle, poor dispersal by adult females, presence of larvae high in the soil profile, and the acidic, organic and friable soils all influence control options and the efficacy of these options.suSCon Blue is giving inadequate control. The insecticide is being placed too deep to contact grubs and the low grub populations in the first two years followling replanting means that the effect of much of the active ingredient is wasted.Knockdown insecticides have a limited potential because of the grub's one year life cycle and because crops are not irrigated.Cultural controls, such as rolling, plough-out and fallowing, and use of tolerant varieties have considerable potential for use as management tools.Green-cane trash-blanketing or trash incorporation may change the farming system in the medium-term future and their effects on rhopaea canegrubs are unkown.There is a core group of growers who are very aware of the problem and who are very enthusiastic about testing alternative and integrated management options.A RD&E plan, which incorporates all of the above options, was developed in conjunction with growers and extension officers. This program should be developed for funding from SRDC and insectide companies and would provide a good project for a postgraduate student. The key components of this program are
