Spyder is a water dispersible granule formulation that offers effective control of a broad spectrum of weeds and undesirable grasses throughout the growing season. Spyder provides preemergent and postemergent activity to control hard-to-kill annual and perennial grasses and broadleaf weeds. The active, a herbicide that is absorbed through the leaves and root system of the weed, subsequently stops growth by inhibiting cell division in the weed's tips, roots and shoots.


  • Dispersible granules for both pre-emergent and post-emergent weed control
  • Absorbed by both the roots and the foliage of the plant, which rapidly inhibits the plant’s growth
  • Controls broadleaf and grassy weeds, also used for conifer and hardwood site preparation
  • Tank-mix compatible with most widely used IVM herbicides
  • Readily mixes with hexazinone (Velpar)
  • Integrated Pest Management uses include chemical weed mowing and suppression of grass seed heads
  • Application only requires a few ounces of product, rather than pounds or gallons like other herbicides


  • 8 x 3 lb


  • Sulfometuron-methyl (75%)
