Nutsedge in leeks

Yellow nutsedge is no ordinary weed for a number of reasons:

  • It belongs to the sedge family, which is why graminicides (=grass-weed herbicides) are not effective against it.
  • There are no effective herbicides for many crops.
  • Basically, it propagates vegetatively (via tubers).
  • The tubers are dispersed everywhere via machinery, vehicles, footwear, etc.
  • The number of tubers in the soil of an infested field increases rapidly.
