    Alternative Strategy: an adjuvant operates by degrading the outer waxy cuticle on the surface of the leaf and therefore allow greater penetration of herbicide such as Glyphosate into the leaf foliage. The adjuvant will be most effective when dessicating some species that are known to be resistant to either Glyphosate or Metsulfuron because of an impenetrable (thick layer of wax) leaf surface. This has effectively replaced the use of Oxyflurfen.

    Alternative Strategy: Cultivation (ploughing): Site cultivation can improve growth conditions by disturbance of existing pest plants, cultivation of the soil and compaction relief. However it does not avoid herbicide use as cultivation also stimulates competing weed vegetation. Used in combination with an appropriate herbicide application, site cultivation can reduce the number of herbicide applications required.

    Alternative Strategy: Boyette et al. (2001,2002) tested Myrothecium verrucaria, as a biological control agent for kudzu. The USDA-ARS biological control team showed that M. verrucaria applied at a high spore rate of 2x108 conidia/ml caused greater than 90% mortality of both young and old kudzu seedlings. They also determined that the disease severity increased with an increase in temperature to 30-40°C, suggesting that this mycoherbicide could be very active in the summer in the southern USA. The virulence of M. verrucaria against kudzu was increased in formulation with an organosilicon surfactant to cause 100% mortality of kudzu in the greenhouse and in the field 2 weeks after spraying at a rate of 2x107. As fungal activity requires the surfactant, the risk of the fungus spreading beyond the sprayed field is minimal.

    Alternative Strategy: On second rotations sites weed control begins prior to final harvesting with the aim of removing woody weeds and reducing weed seed loadings before site preparation commences. Under canopy treatment is standard practice which significantly reduces the potential for off site chemical

    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 returns nutrients in harvest residues back to the site. This will dramatically reduce the fertiliser requirements for 2R plantations which currently require large inputs of chemical fertiliser to remain productive.
