Product Information

SFM Extra-Dry Flowable Herbicide (4 lbs)

SFM Extra is labeled for non-crop sites and conifer plantations to control many perennial and annual types of grass and broadleaf weeds. It may be applied for general weed control on terrestrial non-crop sites, and some vines and wood plants (See label for complete list)

  • For pre-emergent and post-emergent control of herbaceous weeds. Best results are obtained when the application is made before the root system is established.
  • Provides selective weed control in conifer site preparations and the release of certain conifers and hardwoods.
  • Can be tank-mixed with other herbicides registered for use in conifer plantations and non-crop sites.
  • Do not apply more than 10 2/3 ounces of SFM Extra per year per acre.

Conifer Plantations

conifer plantation

Use SFM Extra to control broadleaf weeds, vines, undesirable woody plants, and grasses in conifer plantation sites. You may apply it using ground equipment or a helicopter. As a post-emergent herbicide spray, the best results occur when the application is between full leaf expansion in the spring and normal defoliation in the fall. It may be tank-mixed with other herbicides (see labels)

  • Use rates prior to transplanting conifers (1 1/3 oz- 5 1/3 oz)per acre. These rates depend upon the type of conifer.

Non-Agricutural Uses


Apply SFM Extra as a pre-emergent or post-emergent spray before or during the rainy season when weeds are actively growing or germinating. See the label for a complete list of weeds controlled.

It is labeled for uncultivated lands such as:

  • Uncultivated non-agricultural areas including airports, highway, railroad and utility rights of-way, sewage disposal areas;
  • Uncultivated agricultural areas including farmyards, fuel storage areas, fence rows, soil bank land, barrier strips; and,
  • Industrial sites outdoor including lumberyards, pipeline and tank farms.
  • Use rates: Use between 1 2/3 to 3 oz per acre. For improved weed control, add a surfactant at the rate of 0.25% by volume or at the rate specified on the manufacturer’s label.
