Weed management in pre-sprouted seedlings system of sugarcane
The use of pre-sprouted seedlings (MPB) of sugarcane is a technology that provides sanity, vigor and uniformity of planting with a focus on quality and yield, for the formation of nurseries and replanting of commercial areas, as well as in areas of MEIOSI. However, the presence of weeds can affect the yield by competing for water, light, nutrients and space with sugarcane seedlings. The integration of the cultural, mechanical and chemical methods provides control of the weeds, so that they do not affect the yield and longevity of the sugarcane field. The mechanical control through the break-back operation associated with chemical control is one of the tools used. As well as the chemical control that through the residual herbicides guarantees a greater control of weeds during the establishment of the crop in the field. However, sugarcane seedlings have roots that are in contact with the herbicide in the treated soil layer, affecting the selectivity. Thus, weed management in the MPB planting system provides a field of new studies and discussions.
