inoculum

Catalogue: GRDC Factsheets
Yield losses in crops affected by bare patches can be over 50% and crops with uneven growth (Figure 1) may lose up to 20%... Figure 1: Above-ground symptoms of crop unevenness (main picture) are seen when Rhizoctonia damages crown roots, even when seminal roots (inset) escape the infection... Inoculum levels increase in cereal crops at all depths...

Without appropriate management, diseases can severely impact on the yield and quality of wheat crops in the Wimmera region of Victoria... The Information Note first discusses the integrated management strategies that are required to protect crops from losses due to disease, and then discusses the important diseases of wheat in more detail... For some diseases, a single management strategy is effective, while for others a number of approaches need to be utilised together to ensure effective management...

Rhizoctonia root rot is an important disease of cereals in both the southern and western regions of the Australian grain belt... Experiments in western and south eastern Australia have shown that grass-free canola provides an effective break following cereal crops... Experiments in Western Australia and southern Australia have shown that in-furrow fungicides produced greater and more consistent yield responses than seed treatments alone...

Image of legume root mass showing nodule lumps.. (Photo by J. Doughton, DEEDI) Grain legumes do not need additional nitrogen if the seed is effectively inoculated at planting... Inoculation is important to all legumes, especially under planting situations where: soil has not previously grown the specific legume crop there has been a long time interval between the planting of successive legume crops soil erosion has removed or depleted bacterial populations levelling has exposed lower soil profiles that contain low bacterial populations...

Factors affecting the decline in inoculum with time were identified... The quantity of inoculum produced in a wheat crop can be estimated by multiplying the yield by the proportion of mature plants showing stem browning... The expected outcome is increased yields of wheat, durum and barley in the Northern Region (NR) through improved management of CR. Being able to define more precisely when management for CR is required will assist growers to avoid crop losses when risk is high, and to avoid unnecessary management expenses when risk is low...

Rhizoctonia bare patch disease remains an important but unpredictable disease for cereals in the southern Australian agricultural region... Management of natural disease suppressive ability of soils has been suggested as a potential solution to control Rhizoctonia bare patch disease... The project will address (i) the shorter-term solutions such as rotation, tillage and fungicides to reduce disease incidence and increase plant growth and yield and (ii) will develop new knowledge that will assist in a longer-term control of Rhizoctonia through improving our understanding and management of natural soil suppressive activity & improved prediction of disease occurrence...
