Lots of Sudden Death Syndrome SDS
Liberty Link soybeans
especially the 4.9 maturities and in
other beans
SDS and SCN go hand in hand
SDS
85,000 SCN eggs per
100 cc of soil
Importance of nematodes
SCN accounts for 17% of all disease losses
Root knot nematode becoming big issue
All nematodes account for 35% of all yield
losses- SCN, RKN and other nematodes
Soybeans for severe nematode pressure
• MPV 5214nRR
• Asgrow 5634RR2Y
• Pioneer 95Y60
• Hartwig type Resistance to SCN and RKN
Management of MPV 5214nRR
Best situation for MPV 5214nRR (tall early V)
a) Planted early (in April) or late (after wheat)
b) On sand - nematode pressure (SCN, RKN)
c) After potatoes – RKN and SCN pressure
d) Avoid soils where growth is excessive
e) MPV 5214nRR is sensitive to Metribuzin
Do not use Sencor on MPV5214nRR
New RR1 lines with nematode resistance
2015 release
Putting these on the fast track for release
• S09-20356RR1 (4.9 with SCN & RKN)
• S09-20124RR1 (5.2 with SCN & RKN)
Key Features - S11-20356 RR1 (4.9)
- S11-20124RR1 (5.2)

Soy-oil with >70% Oleic Acid will
• Increase heat stability, taste & shelf-life
• Be healthier with more food applications
• Reduce hydrogenation & trans-fats
• Improve soy-diesel, lubricants
• Be used more in pharmaceuticals &
cosmetics
GMO sources of HI oleic• Pioneer-DuPont- “Plenish”
• Monsanto- “Vistive gold”
First Products- Groups II and early III
• US farmers serious about getting high

How does the MU high oleic trait affect
seed yield, protein and oil
Evaluate MU non- GMO high (75-80%) and
normal (20-25%) oleic acid soybean lines from
five crosses grown over six environments
1) seed yield
2) oil and protein content
3) oil fatty acid profile

Conclusions- U of MO high vs normal oleic
• Equal in yield- No yield penalty
• High oleic varieties show added benefits
–Generate more oil with better quality
–Higher protein for premium meal (50%)
• Greater food value
• Greater feed value
