Controlling Pests and weeds on your plantation

Banana fruits develop in a large hanging cluster, made up of tiers (called ‘hands’), with up to 20 fruit to a tier. The hanging cluster is known as a bunch, and can comprise three to 20 tiers.

Once your banana plants are growing, cover the bunches with bags for protection against insects and wind.

At the same time, remove lower-hanging yellow leaves. This will result in better quality bananas. Remove the lower leaves from the plant as they get old because they can spread diseases and scratch the bunches.

Use a knife to cut off the leaves, do not pull them. Place the leaves on the ground as mulch to increase the nutrient content of the soil. Banana plants usually need support when heavy with fruit; provide this by propping the bunches with a rope and sticks.

To control weeds, Use only recommended chemicals applied strictly according to the instructions on the label. Do not spray the banana plants or spray when it’s windy.

When using chemical control, such as glyphosate or paraquat, protect all parts of the banana plant from spray drift.
Use a hoe or your hands to kill weeds in the area near the plant to avoid chemical spray contact with the plants.

Pest and disease control
Thrips: Use chlorpyrifos pesticide once a month to kill thrips if they are present.

Nematodes: If these are present, kill them with Nemacur using 45kg/ ha (20g/plant). Compost, kraal manure and chicken manure applied in ample quantities will also suppress nematodes. Tissue culture plants are free of nematodes, which is one of the reasons that this is the preferred method of cultivation.

Black sigatoka: Plants with leaves damaged by the disease may have up to 50% lower fruit yield. Spray with Dithane and mineral oil. The latter enhances the penetration of the fungicide in the leaves and reduces leaching from rain. Ask your extension officer or chemical rep for advice. Finally, dip the banana hands into Benlate solution (5g/10l water) to prevent post-harvest decay.
