PEST MANAGEMENT DECISION GUIDE: GREEN AND YELLOW LIST
Fusarium Wilt or Panama Disease on Bananas
Fusariumoxysporium
Yellowing of older leaves
(Rose Kamau-MoA Kenya)
Brown red ring like lines (Rose
Kamau-MoA Kenya)
Prevention Monitoring Direct Control Direct Control Restrictions
Use plant tolerant varieties
like; Dwarf Cavendish, Giant
Cavendish, Apple, Lacatan,
Valery and Poyo
Select a clean field with no
disease history.
Always use clean planting
materials and avoid movement
of materials from infected
areas to uninfected sites.
Sterilize working tools by
dipping them for one minute
into bleach, Methylated spirit
and Formalin after working
with infected plants.
Before planting can sterilize
the planting materials by
dipping into a fungicide
solution (see yellow direct
control)
Use only clean suckers from
plants that are healthy or use
tissue cultured materials.
Avoid runoff water from
diseased areas as fungus can
be distributed with the water.
Can use the Kitchen manure
on the plants
Continuously monitor
for light yellow
colouration on the
lower leaves. (Mainly
around the margins.
The yellowish
colouration
progresses from
older to younger
leaves leading to
wilting of the whole
plant.
The stool of the
affected banana
shows purple-brown
patches when cut
across.
The pseudo stem
show a distinctive
symptoms of brown,
red or yellow ring like
lines on the cross-
section
On the infected
plants; leaves
collapse and drop
towards the pseudo
stem.
Apply direct control
when Fusarium wilt
is first detected.
Incorporate
Trichodermaspp at
the rate of 10g per
plant as dried
banana leaf
formulation.
Mix ash with water
and pour onto the
basal part of the
plants.
Uproot the affected
banana stools in
the farm and leave
them on the
surface to dry. Can
also burry them or
put into plastic
bags and burn.
Isolate the infected
stool then inject
with an herbicide
like glyphosate
Add urea to
catalyse
decomposition of
the uprooted
diseased materials
Dip stools before planting:
Mancozeb and
Metalaxyl
Didecyldimethyl
ammonium chloride
Propamocarb
Fludioxinil solution
Mancozeb: WHO U (unlikely to
cause harm)
Metalaxyl: WHO III (slightly
hazardous)
PrepomacarbWHO U
Fludioxyl WHO U
Treat with herbicide
(Glyphosate) to kill
infected stool
WHO III (slightly hazardous)
Treat infected soil with
Metam sodium (soil
fumigation)
WHO II (moderately hazardous)
Should only be applied by a
professional
No plants must be present during
treatment
Very toxic to aquatic organisms
Keep unprotected persons, livestock
and pets out of treated areas for at
least 24 hours
Allow several weeks to dissipate
