Propagate Success with Clean Suckers
The propagation of disease-cleaned suckers involves two main techniques: field-based and detached corm methods. Field-based techniques include complete and false decapitation, stimulating lateral production of sucker buds by destroying the meristematic corm. Partial decapitation involves making a hole in the pseudostem to destroy the meristem. Detached corm techniques use excised buds or plants resulting from stem fragments, producing a higher number of seedlings with greater growth uniformity. It's crucial that starting material for macro-propagation is free of pests and diseases. Clean knives and hardened sprouts are essential for all methods to prevent disease transmission. Additionally, a propagation chamber of specific dimensions is used, filled with a substrate mixture sterilized by steam to ensure optimal conditions for growth.
This technology is TAAT1 validated.

The United Nations Sustainable Development Goals that are applicable to this technology.
False Decapitation:
a. Select a 6-month-old banana or plantain plant.
b. Incise the pseudostem at 20 cm from the ground level, creating a square hole.
c. Angle the bottom side of the hole slightly downwards to collect water and sap.
d. Leave the decapitated plant for at least one month to allow for sprouting.
e. After sprouting, detach suckers with three to four leaves and transplant them to the field.
Complete Decapitation:
a. Choose a 6-month-old plant.
b. Cut down the plant to ground level.
c. Excise the middle 5 cm of the softer meristem, leaving the harder corm intact.
d. Cover the cut stem with soil to promote sprouting.
e. Within three weeks, four to seven suckers will emerge.
f. Detach suckers with three to four leaves and transplant them to the field.
Detached Corm Technique:
a. Collect healthy suckers between flowering and harvest.
b. Cut roots from the suckers and wash them.
c. Peel the leaf sheaths from the suckers.
d. Submerge the whole corm in boiling water for 30-40 minutes or use fungicide for 20 minutes to sanitize.
e. Scarify the corm by making a shallow incision at the top.
f. Let the corm air dry for 24 hours.
g. Plant the whole corm in the weaning chamber at a 30 cm distance or split it into 2 or 3 fragments/buds and plant at a 10 cm distance.
h. Cover with 2 cm of sawdust.
Weaning Chamber Preparation:
a. Create a propagation chamber with dimensions 1.5 m wide, 5 m long, and 1 m high.
b. Cover it with transparent polyethylene, ensuring at least 50% shading.
c. Fit plastic covers to maintain high humidity and temperature.
d. Fill the chamber with a substrate mixture of soil, composted manure, and sawdust or other materials at a ratio of 6:3:1.
e. Steam-sterilize the substrate by placing it on top of a metal drum containing boiling water.
Knife Sterilization:
a. Clean knives with boiled water before use to avoid disease transmission.
b. For the detached corm technique, ensure that knives are specifically cleaned when using hardened sprouts.
Propagation Unit Setup:
a. Determine locations for macro-propagation units and nurseries.
b. Develop a timeline for unit setup.
c. Mobilize materials and resources for unit setup.
d. Specify activities involved in setting up and maintaining the units.
e. Establish a plan for sharing/distributing planting material.
f. Ensure financial and environmental sustainability of the unit.
