Better control of Chenopodium album was achieved by using low rates of herbicides in combination with toxins from Ascochyta caulina Vurro et al. 2001 . Jahromi et al. 2006 studied interactions between herbicides and Plectosporium alismatis to control starfruit in rice. Kropp Darrow 2006 found that herbicides and surfactants did not negatively affect teliospore viability of Puccinia thlaspeos when it was sprayed on to Isatis tinctoria Dyer s woad plants in the field. Abu-Dieyeh Watson 2006 examined the relationship between the fungal pathogen Sclerotinia minor Jagger applied with different turfgrass mowing heights compared to herbicide alone to control dandelion. In the greenhouse S. minor caused greater damage to dandelions than the herbicide at all mowing heights however under field conditions close mowing had an unfavorable effect on Sclerotinia minor for dandelion control. Magani et al. 2009 demonstrated that the fungal mycoherbicide Fusarium oxysporum when applied in granular form followed by a post-emergence herbicide treatment was successful in controlling the parasitic plant Striga in Nigeria. Peng and Byer 2005 tested seven herbicides at reduced rates to determine whether there might be synergistic effects with Pyricularia setariae for control of green foxtail. Responses were variable and depended on weed growth stage herbicide and application rates. However each of the herbicides at a one-quarter rate applied with a sub-lethal dose of the biocontrol organism succeeded in controlling green foxtail in the greenhouse Peng Byer 2005 . Jahromi et al. 2006 studied interactions between the .
