General Comment
Interpretations are based only on the data provided with the sample and the results of the DNA analysis. Clients should not rely on these interpretations as the sole source of advice as seasonal conditions, paddock history and other agronomic factors may affect crop performance. Primary focus should be on CCN management. Implement control strategies such as two-year break from susceptible cereals and host weeds, reduced soil disturbance and regular use of resistant cereal varieties.

Comment
(Comments in bold are high priority)
CCN
23 eggs / g soil
High
Potential yield loss in susceptible cereals is in the range of 40 - 90%. Sow canola, pulses, pasture legumes or fallow. DO NOT plant cereals. Note that oats are the most sensitive of all cereals to CCN. Some varieties of oats have a degree of resistance and tolerance to CCN but at this level probably inadequate for effective management.
Take-all
32 pg DNA / g soil
Low
Potential yield loss in susceptible cereals is in the range of 0 -10% and the presence of oats race of take-all means that the proposed oats crop is not a suitable break. In addition the high level of CCN should be noted as this largely rules out all cereal options. Alternatives should be considered but choice of pulses will be limited due to high blackspot levels.
Take-all - (Oats Race)
Present
Oats race presence means oats are not a suitable rotation crop for take-all management
Rhizoctonia
<19.5 pg DNA / g soil
BD
Pratylenchus neglectus
2 nematodes / g soil
Low
There is only a low risk of yield loss.
Focus on other diseases
Pratylenchus thornei
17 nematodes / g soil
Low
As with P. neglectus above, the low level of this nematode also indicates minimal risk of yield loss in cereals. Focus should be on other pathogens, in particular CCN.
Blackspot
170 DNA / g soil
High
Although peas are not intended the high level of black spot should be noted. Peas should not be considered as an alternative crop and volunteer peas should be controlled to reduce inoculum.
Crown Rot (F. pseudograminearum)
44 pg DNA / g soil
Low
Yield losses in durum may be up to 20%. Durum is not recommended. Yield losses in bread wheats may be up to 5%. Durum is more susceptible than bread wheats but levels are still in the low range with yield losses in durum probably under 5%.
Crown Rot (F. culmorum)
6 pg DNA / g soil
Low
Levels detected are at the low end of low risk range for bread wheats. Yield losses likely to be minimal. Monitor next season.
