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. A cereal
rotation program is assumed and where possible interpretations refer to the
planned crop and cultivar advised with the sample. Both F. culmorum and F.
pseudograminearum are present. It is not yet known whether the effects of the
two fungi are additive.

Comment
(Comments in bold are high priority)
CCN
<1 eggs / g soil
BD
Take-all
320 pg DNA / g soil
High
Despite a two-year break take-all levels remain very
high. Potential yield loss in susceptible cereals is in the range of 15 -
60%. Consider alternatives to wheat. Soil inoculum levels should decline if
summer rainfall events of 25mm and above occur and weeds are controlled.
Therefore, if sowing susceptible cereals delayed planting should reduce risk.
Good nutrition, particularly P, N and Mn, will help in early crop
establishment and take-all resistance. Control of grasses in selected crop or
pasture is a high priority for effective take-all management.
Take-all - (Oats Race)
Present
Oats race presence means oats are not a
suitable rotation crop for take-all management
Rhizoctonia
69 pg DNA / g soil
Medium
Potential yield loss in intolerant
cereals is in the order of 5 - 20%. Important management strategies include
cultivation to break up the fungal network, good weed control (if early break
control weeds when small) and attention to nutrition, particularly Zn, N and
P.
Pratylenchus neglectus
4 nematodes / g soil
Low
There is only a low risk of yield loss.
Focus on other diseases
Pratylenchus thornei
<1 nematodes / g soil
BD
Blackspot
38 DNA / g soil
Low
Black spot levels are low but given that
peas are not intended this should not be an issue. If peas were to be
considered a yield loss of 5-10% could occur.
Crown Rot (F. pseudograminearum)
74 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%.
Crown Rot (F. culmorum)
26 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%.
