Definitions

  • Sugarcane is an important crop because of its many uses including the production of molasses, brown sugar, sugar, ethanol, and alcoholic beverages. Sugarcane can be used for animal feed and sugar waste may be converted to fertilizer and fuel. Sugarcane is grown on approximately 10MM ha in Brazil, with the acreage likely to increase in the future. The 2020/2021 harvest in the South-Center region of Brazil was 603 million tons. A portion of the harvest was used to produce alcohol, with a total alcohol production of 29.7 billion liters. Other countries where large scale sugarcane production occurs include India, China, Mexico, Thailand, Pakistan, Colombia, Australia, Indonesia, and the United States.
  • grass and broadleaf weeds are known to compete with sugarcane, lowering crop yields and causing problems for harvesting equipment.
  • broadleaf and grass weeds such as Ipomoea spp., Merremia spp. , Miicuna spp. , Riccinus Communis, Brachiaria decumbens, and Panicum maximum, are problematic.
  • Pre-emergent herbicides can be used — and are sometimes preferred — to control weeds in sugarcane, and mixtures of active ingredients are frequently employed. In some mixtures, active ingredients having pre-emergence activity are combined with ingredients that possess postemergence activity. Herbicide mixtures used to control weeds in sugarcane may exhibit control for 90 days or longer. Effective long term weed control can eliminate the need for subsequent post-emergence herbicide treatments.
