| Popis: | The colonisation of plant roots by biological control agents is dependent on abiotic factors one of the most important being soil pH The rhizosphere and endophytic colonisation of ryegrass and sweet corn roots by the biological control agent Trichoderma atroviride LU132 were assessed in a pot experiment with nonsterile soil at three different pHs (55 65 and 75) T atroviride LU132 colonised the roots of both plants regardless of the soil pH with 113147 x 106 CFU/g of dry rhizosphere soil (DRS) for ryegrass and 136350x105 CFU/g DRS for sweet corn T atroviride LU132 was able to colonise both plants endophytically regardless of soil pH However the isolate was recovered from entire ryegrass roots but only from the upper parts of sweet corn roots These experiments demonstrated that T atroviride LU132 colonised the rhizosphere and roots within a soil pH range common to most NZ soils which is a desirable trait for biological control agents |
