    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: A combination of glyphosate and imazypyr. Imazypyr has long residual action and is being trialled on firebreaks to see if it reduces the number of times firebreaks must be sprayed.

    Alternative Strategy: Elders Forestry has piloted a system of taking harvest residues deposited at harvest landings after in field chip operations and mulching and re-distributing them across the site to provide a mulched layer which suppresses weed growth

    Alternative Strategy: There seems to be a relationship between phosphate levels in soils and insect pests whereby phosphate deficient soils often have problems with insect attack on trees whereas phospoate rich soils seem to hardly ever need treating. By factoring this into site selection or soil fertilisation stragies it seems possible to forgoe chemcial intervention for insect attack. Although the correlation noticed is 100% this has not been properly verrified with trial work.

    Alternative Strategy: Experimenting with polymer coated fertilisers that can be placed in the planting hole in direct contact with the root ball. Early indications are that this may lead to rapid initial growth and hence reduce the need for post plant weed control and browsing animal control.

    Alternative Strategy: Together with the Site Management Research Co-op, certificate holders optimised area and duration of spot treatment of weeds in radiata pine.

    Alternative Strategy: Mycoherbicides are microbial pathogens which (ideally) control certain introduced plants selectively. Many rusts are highly host-specific, affecting only few or a single plant species. Besides the fungus Fusarium tumidum which attacks gorse, mycoherbicides include the rust Puccinia chondrillina that successfully controls skeleton weed (Davenhill 1997), the rust Phragmidium violaceum used against blackberry (Rubus) species (Julien & Griffiths 1998), and the fungus Chondrostereum purpureum which for control of stump sprouting of broad-leaved trees (Becker 2005).

    Alternative Strategy: Fallowing Might be an option on upland sites where competing vegetation is not a major issue. As weevils only emerge from stumps for the first 4-5 years after felling, one obvious option would be to delay replanting until the number of emerging weevils falls below economically damaging levels.
