 Land must beploughedand refineup
to20cm deep.
 Furrowingand ridges should be
established.

7. PLANTING &
SPACING
 Dig holes 1m alongand betweenrows
 Place seeds (Ifnot planting by seedlings) at1cm
in dept and coverlightlywith soils.
 Timeofplanting:
Traditional Red: May -August
Manchester Black: April-June
Bashment: Allyear round

8. GERMINATION
 SEEDS GERMINATEWITHIN3-7DAYS
 N.B.THESEEDS OFTHEBASHMENT CULTIVAR EXPERIENCE
HARDSEEDINESS
Solutions: -Soak seed in hot waterfor 5min
-Expose seeds toheat (60-70oC) for1-2hrs
-Impactof seeds against ahard surface.

9. FERTILIZATION
 Initiallya Soil analysis isrecommended
 A general recommendation is 8 bags fertilizer
(11:22:22) per hectare, applied at planting or by
2wks aftergermination.

11. IPM (INTEGRATED PEST MANAGEMENT)
Whatis lPM?
IPM a is safe approach to pest control in
Bangladesh. It uses a mixture of ways (Integrated) to
prevent crop damage and protect man, helpful
creatures and the environment (soil, water, air, other
creatures) (Management).

12. TYPES OFPRACTICES

13. CUL
TURALPRACTICES
Normal field work is used tomake field conditions best for the crop and worst for
pests.
Site selection
Preparing land early and properly.
Using pest-free plantingmaterial.
Spacing toreduce overcrowding and diseasebuild-up.
Checking fields weekly forproblems (scouting).
Feeding plants forearly,healthygrowth.
Early removal of sick plants from fields.
Crop rotation.
Reaping on time toescape pestdamage.
Reaping withcare toreduce bruises androts. 13

14. BIOLOGICALCONTROL
In nature, many creatures kill pests.
The three types of beneficials (Natural
enemies) are:
-Parasites
-Predators
-pathogens.

15. OTHER BIOLOGICALCONTROL
ResistantVariety
Biorationals eg. pheromones

16. CHEMICAL CONTROL
Pesticides are made tokill pests. Most
pesticides willalso kill or harm otherliving
things.
Some are verypoisonous; others less
dangerous toman, beneflcials andthe
environment.
Botanical insecticides are made fromplants.
Some are safer andstill quite effectiveagainst pests

17. MAJOR PEST OF REDSORREL
 Weeds
 Thrips
 Root KnotNematodes
17

18. THRIPS
 Verysmall
 Infestfruits
 Major problem tothe exportmarket
Control
-IPM
-Appropriate insecticide
(eg.Aecis orDiazinon).
18

19. ROOT KNOT NEMATODE
 Small worms living inside theroots
Can reduce the yieldof the plants
Control
IPM (croprotation)
Use of nematicide.

20. MAJOR DISEASES OF RED SORREL
 Powdery Mildew
 Leaf Spot
20

21. POWDERY MILDEW
 Fungal Disease affecting the leaves of the
plant.
Sign: leaves appear whitein color
Control:
=IPM (cultural practices)
=Use appropriate fungicide. (eg. Champion)

23. LEAFSPOT
Fungaldisease
Appears in a circularpatternand can result inleaf
drop.
Control:
=IPM
=use of appropriate
fungicide (eg.Carbendazin)
23

24. HARVESTING
Major challenge in sorrel production
Clip fruits individually from the plant.
Theuse of an umbrella’s main vein is use toeasily separate
the seed from the calyx.
Store Calyx properly and move tomarket as quickly as
possible.
