Alternative Strategy: Control is based upon the weeds present and the weeds likely to be present, environmental or operational restrictions, soil type and characteristics (fine sand 1st rotation sites tend to blow away with broadcast spraying resulting in top soil erosion and sand blasting of seedlings), topography, site preparation method (spot cultivation, mounding, line marking only), preferred application method (aerial or ground based) and for second year weed control sites the growth already achieved since planting. Under advice from the research section, where practical, expensive and high application rate are used low rate, lower risk and lower cost products can be substituted.

Alternative Strategy: GPS Linked Flow Metering. In conjunction with aerial applicators Timberlands Limited are trialling flow metering linked to GPS. If successful this will allow application rates to vary depending on the known plant pest infestation. Therefore rather than applying a rate to control the worst infested areas across the entire site, lower rates can be applied to areas of lower infestation. This will lead to less active ingredient being applied to the site.

Alternative Strategy: Application Rate Reduction. Timberlands Limited have trialled different rates on the many weed species and infestation levels. This has allowed Timberlands Limited to best select the herbicide and rates for the control required. In most cases this has lead to an active ingredient rate being applied lower than recommended by the pesticide manufacturer and label detail. It should be noted that the rate of Terbuthylazine has reduced from around 20l/ha to between 12 and 15 l/ha over the past 15 years. These trials are continuing in conjunction with the flow metering and Callisto trials.

Alternative Strategy: In New Zealand, significant progress towards a bait-delivered contraceptive vaccine for possums is expected within the near future. The system of delivery still poses some challenges and immigration of fertile animals from non-treated areas may compensate for treatment effects. Population models indicated that fertility control can be effective where population reduction does not have to be as rapid as lethal techniques, or where the objective is to maintain a population at low levels established previously with exclusion or lethal techniques. Fertility control is not likely to be useful for short-term, localized management of browsing damage, e.g. during the establishment phase
