1

FIRST STEP

Select a suitable site that is not slopy, waterlogged, stony or very shallow. The presence of biological activities such as worm cast is an indication of good soils.

2

SECOND STEP

If the vegetation is older, fallow or too tall to go over it with a sprayer, slash the vegetation and allow regrowth for about two weeks. Thereafter, apply glyphosate (E.g RoundUp Turbo, TouchDown Forte, Sarosate, ForceUp, Delsate, etc) at label rate to deal with perennial weeds such as Imperata cylindrica (Speargrass) and Panicum maximum (guinea grass), Mimosa invisa, Ipomea mauritiana, Chromoloena odorato, Wait for 14 days to allow total kill by glyphosate.

3

THIRD STEP

If the vegetation is young (less than one year) and of low growth (less than one meter tall), apply glyphosate (E.g RoundUp Turbo, TouchDown Forte, Sarosate, ForceUp, Delsate etc) at label rate to deal with perennial weeds such as Imperata cylindrica (Speargrass) and Panicum maximum (guinea grass), Mimosa invisa, Ipomea mauritiana, Chromoloena odorato, Wait for 14 days to allow total kill by glyphosate.

FOURTH STEP

Plough, harrow, make ridges or mounds.

5

FIFTH STEP

Plant cassava only when the soil is moist at 1m x 0.8m or 1m x 0.7m (12,500 – 14,300* plants/ha) and apply pre-emergence herbicide such as Lagon at 1.25L/ha or Primextra Gold at 4L/ha within 24 hours after planting. Do not apply pre-emergence herbicide on dry soil. Visit your farm regularly. Replace cuttings that fail to sprout after 15-21 days.

SIXTH STEP

When weeds cover 30 percent of your field and they are at 4-6 leaf stage, apply a post-emergence weed control (E.g post-emergence herbicides, mechanical or manual weeding). In grass dominated fields or in portions of a field that is grass dominated, apply Fusilade forte at 3L/ha under cassava canopy. For grass and/ or broad leaf-infested fields, glyphosate may be applied directly to weeds under cassava canopy with a shield when cassava is 8 weeks old and above. If cassava is less than 8 weeks old and the field is infested with grass and broadleaf weeds, use manual weeding method to remove weeds. Avoid glyphosate touching green cassava stems/leaves.
