    Alternative Strategy: A. areolatum is a basidiomycete that causes a white rot of a broad range of conifers. Its invasiveness arises from a symbiotic association with wood wasps of the genus Sirex. Control strategies therefore need to address both the fungus and they symbiotic wasp.The tylenchid nematode Beddingia (= Deladenus) siricidicola, discovered in New Zealand and later found in Europe lives in and feeds on A. areolatum colonies in trees and also infects Sirex larvae and female wasps. Because it has a separate cycle of growth and reproduction based on fungus feeding, it can cause a greater reduction in wasp numbers. The nematode can be raised in cultures of the fungus and injected into trees for effective control of the wasp (Bedding, 1995). B. siricidicola is currently under evaluation for use in the USA (Williams and Mastro, 2009.

    Alternative Strategy: González Audino et al. (2005) identified the male M. mutatus sex pheromones, which are being tested with various traps to examine their efficacy at attracting females in the field. These would be useful in monitoring population peaks (OEPP/EPPO, 2009).

    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.
