When weeds grow faster than cane – the whole crop is at risk!

"Ten days after planting, all I could see was… weeds. No cane in sight, just thick green weeds!"

This is common in most sugarcane-growing areas in Vietnam, especially when:

  • Cane is planted at the start of the rainy season
  • Pre-emergence weed control is not applied right after planting
  • The soil holds many weed seeds and is not cleaned before the season

Consequences:

  • The cane lacks light → weak growth
  • Competition for nutrients → slow growth, yellow leaves
  • More pests and diseases such as thrips, stem borers and red spider mites
  • Repeated weeding with short-lived results

Weeds – taking away sugarcane's "chance to grow"

HarmEffect in the field
Take up nutrients faster than caneCane lacks nutrients, grows poorly
Block light and cast shadeCane cannot photosynthesise well
Shelter pests and diseasesFast spread while cane is young
Grow too earlySmother cane shoots – the crop loses its head start

In practice: cane needs 7–10 days to root – weeds need only 2–4 days to take over the soil

Weeds:

  • Grow from seeds and underground stems; their roots survive for years
  • Are always "waiting" for moisture + warm temperatures → grow faster than cane

Without measures to stop weeds from the start, you will need 3–5 weeding rounds per year → higher costs – lower yields

✅ Solution: Control weeds right after planting – with a pre-emergence herbicide

Spray herbicide 1–2 days after planting, while the soil is still moist

Use a product that does not affect cane buds, targeting broadleaf weeds, grasses and sedges

Add a sticker–penetrant adjuvant for better results

Xinron 800WG is one such solution – designed for sugarcane land, with strong activity for clean weed control in the critical stage.
