Shark H2O

Quick Facts

  • No required draining or lowering the water level in basins
  • Controls key broadleaf weeds and sedges, including those tolerant to ALS herbicides such as ricefield bulrush, smallflower umbrellaplant, redstem (purple ammannia or redstem ammannia) and California arrowhead
  • Applied by air with a DDA or DSA deliver so there’s no hassle using ground application equipment
  • Can be applied sooner than most competitive products
  • Less weed competition early means your rice crop gets off to a healthier start
  • Can be applied in a sequential program with grass herbicides such as Ordram®, Bolero®, Abolish® or Cerano®
  • The active ingredient is absorbed into the foliage of weeds to inhibit photosynthesis, which ultimately provides weed control
  • Registered for use in California only
