4. Large
distribution, primarily the
southeastern states
Found in low-lying, wet
areas, disturbed
sites, road ditches, stream
banks
Grows in a variety of
soils, heavy clay to sandy
Grows best when soil
temperatures are
warm, optimal over 800 F
5. Indian Jointvetch
• Aeschynomene indica
• Commonly mistaken for Sesbania
• Grow in similar habitats and conditions
• Shorter plant
• More leaflets
• Leaflets become shorter at the end of
the leaf causing a pointed shape to leaf
• Darker green color
• Less pungent smell
6. Control
• When is the population high enough to need
control?
• Methods of control
– Fertilizer
– Mechanical
– Water management
– Herbicide
7. Fertilizer
• Nitrogen, granular urea 46-0-0
• Why does this work? Competition or direct
impact on the sesbania plant
• When to apply
• Application rates
• Pilot study on Ten Mile Pond CA
8. Pilot study at Ten Mile Pond CA
• University of Missouri Extension
• Four test plots for sampling
• Each plot was treated with different rates of
nitrogen; 0#/acre, 25#/area, 50#/acre,
100#/acre
• Numerical but not statistical difference in the
number of sesbania plants
9. Mowing
• Mow before the plants
produce seed
• Works best where the
plants occurred in a
narrow strip or isolated
spot
10. Disking
• Disk prior to seed
production
• Fits in well with regular
moist soil management
11.
12. Water Management
• Not an option for everyone
• Dewater earlier, promote earlier germinating
plants
• Competition is the best control
13. Deep Soil Disturbance
• This works with a new
population of plants
• Seeds are still viable for
5+ years
• Works great in some
places, disaster in
others
14. Herbicides
• Follow the label
• Costs
• Herbicides affect other plants
• Don’t forget the surfactant or crop oil
16. • Low cost
• Very effective on
Sesbania but equally
effective on all
broadleaf plants
• Drift potential
• Some states have
specific restrictions
• ½ - 1 pint/acre
17. • Good herbicide for moist
soil management where
2,4-D is not an option
• Not as cheap
• It is labeled to control
smartweed but the
smartweed recovers
• Use prior to sesbania
bloom
• Full rate 1 ½ pints/acre
because of plant height
• Work well with crop oil
1-2 pints/acre
• Not effective on
jointvetch
18. • Combination for
spraying adjacent to
water bodies
• Surfactant is important
• Order of mixing is
important
• Sesbania is not listed on
the Garlon 3A
label, however it works
• Rodeo; 1 ½ - 2%
solution
• Garlon; 2-2 ½ pts/acre
