Plant Pathology Team Objectives
Allen Wrather
Objectives:
The purpose of the MU-Delta Center Plant Pathology Team is always to
help the citizens of Missouri, and we have 2 overall objectives to
accomplish that: 1) to discover new and better ways to protect
soybean, cotton, and rice from diseases, and 2) to deliver
information about the most effective methods for control of diseases
of these same crops to members of the agriculture community.
Current Research Projects:
- Compile estimates of soybean yield suppression due to diseases
in the USA from 1996 to 2005.
- Determine the correlation between drought tolerance of soybean
and tolerance to charcoal root rot.
- Search for soybean lines resistant to charcoal root rot, frogeye
leaf spot, stem canker, and root-knot nematodes to include in the
soybean breeding program.
- Site-specific detection and management of root knot nematodes in
cotton.
- Determine effect of seed applied and infurrow applied fungicides
for control of cotton seedling diseases.
- Site-specific detection of rice stress due to nitrogen
deficiency and diseases using remote sensing.
- Evaluate foliar fungicides for control of rice sheath blight.
Major Accomplishments Since 2002:
- We determined that soybean cyst nematode (SCN) caused more
damage to soybean in the USA than any other disease during 1999 to
2002.
- We determined that SCN was present in 63% of Missouri soybean
acres, that SCN races 1, 2, and 3 accounted for 86% of those in
Missouri, and that the value of SCN damage to Missouri soybean in
1999 was $58 million.
- We determined that Phomopsis seed decay of soybean can be best
controlled with resistant soybean lines SS 93-6012 and 93-6181, and
that foliar fungicides are not very effective for control of this
disease.
- In 2004, we published the book titled "The Biology and
Management of Soybean Cyst Nematode, Second Edition."
- We determined that planting rice in no-till or stale seedbed
(disk fall only) fields yielded similar to rice planted in
conventional till (disk fall and spring) fields.
