Consider rhizoctonia seed treatments to boost cereal yields.. Daniel says the take home messages from the trials are that in-furrow banding of fungicide 2-3cm below the seed can provide protection to crop seminal roots and surface banding behind the press wheel can protect the crown roots... Daniel says there are some promising fungicide banding treatment options for rhizoctonia in the pipeline that performed well in the trials...

" Beneficial Microbes Program - progressing new microbial products for Australian grain production to commercialisation... Australian farmers are keen to reduce on-farm chemical inputs and replace them with biological alternatives... Research has shown that the soil biota can be manipulated for the benefit of crops through management practices, such as tillage, stubble retention/burning, crop/pasture sequencing and liming...

New fungicides to tackle Rhizoctonia.. Paul Bogacki (left) from SARDI and Jack Desbiolles from the University of South Australia, discuss the plot layout for the Rhizoctonia fungicide trial, which has included surface, seed and deep placement of the fungicide... Research results indicate the risk of Rhizoctonia damage will be reduced for: cereals following grass-free canola, pulses and pastures; crops with rapid early root growth down the soil profile - consider sowing early with soil disturbance below the seed, deep band nitrogen and new fungicide seed dressings; and registered fungicide seed dressings used in paddocks with low to moderate levels of Rhizoctonia..

Inoculum levels in the medium rainfall zone of the western region have been increasing in the last few years... The disease is caused by Rhizoctonia solani AG8, a fungus that grows on crop residues and soil organic matter and is adapted to dry conditions and lower fertility soils... The fungus causes crop damage by pruning newly emerged roots (spear-tipped roots) which can occur from emergence to crop maturity...

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...

" GCTV9: Banding Fungicide in Cereals 17 December 2012 Field trials show the placement of fungicide above and below the seed as cereal crops are sown improves the level of protection against Rhizoctonia... 34.2: Alan McKay: Principal Scientist SARDI This particular plot we have barley and the 40.93: three rows of this side have had the fungicide applied deep banded below the seed... The plant has a seed treatment, which is the current 288.96: practice for people trying to use fungicides to protect plants from Rhizoctonia, so the 293.59: seminal root system is not too bad but we 299.599: we 306.199: good protection of the seminal roots and we 310.289: So it looks like we 315.449: help support some banding recommendations for these new fungicides...

The overall objective of this research program is to develop and deliver strategies for management of plant diseases of importance to SA grains industries... The increased frequency of cereals and greater adoption of susceptible cultivars is creating an opportunity for cereal cyst nematode (CCN) to re-emerge as a significant problem in the southern region... Subproject 3 continues existing monitoring and surveillance of new races and pathogen threats; this subproject will link with newly appointed grains biosecurity officer in SA. Subproject 4 focusses on rebuilding a joint capability in the southern region to address key issues in cereal nematology, most critically preventing CCN re-emerging as a significant problem...
