How to control cyperus grass in a maize crop

  • Motha (Cyprus rotdans) is a perennial plant growing up to 75 cm tall. The stem is erect, triangular and without branches, above the ground. There are 6 to 7 tubers in the root below, they become padded white and later fibrous brown and finally become hard like wood as they get older. The leaves are elongated, often covering each other on the stem.

  • Motha grass is a big problem for the farmers who have been farming for years. Motha emerges as a major factor in reducing the productivity of crops in farmers’ fields. It is a perennial grass and affects almost all the crops but it mainly affects the maize crop.

  • It is very important to control annual weeds like Motha (Cyperus rotundus, Cyperus species). For its control, at 20-25 days after sowing, spray Halosulfuron Methyl 75% WG @ 36 gm/acre.

  • For good and long results, it is very important to have moisture in the field for a long time, so if the moisture is decreasing then light irrigation must be done.
