NY99046 - Interactive Effects of Mycorrhiza and Trichoderma on Plant Performance in the Nursery and Field Phase

Beneficial soil bugs are destined to play an important role in nursery management systems that minimize the application of synthetic chemicals. Such microorganisms are currently not used routinely in the Australian nursery industry despite evidence of their value in combating disease and in promoting field growth. Many aspect6s of plant growth were measured including shoots and root weights, plant heights and width, stem diameter and the level of colonization of the root with mycorrhizal fungi. Each experiment included a total of 16 treatments that were replicated and randomly laid out in a way that allowed rigorous statistical examination of the data. The evident that emerged in this project supports ongoing evaluation of mycorrhizal and trichodermal technologies in the nursery industry rather than promotion for their widespread adoption.
