Dimension Two Herbicide Half Gallon

Dimension 2EW Herbicide - 0.5View On Amazon
Gotcha, this Dimension Two spray will knock your socks off with its magical powers of pre- and post-emergence crabgrass control.

With the active ingredient dithiopyr, this half-gallon jug stops crabgrass and other annual grasses before they spread through your lawn’s root system. The blue dye lets you see exactly where you’ve sprayed for an even application across your entire yard.

Unlike some pre-emergents, Dimension Two allows you to overseed in the spring, then apply for summer weed prevention. Mix it with water in a backpack sprayer for full coverage without bare spots. Be aware that it takes significant rainfall to water in the chemical after application.

While effective on broadleaf weeds, other options like 2,4-D may work better for dandelions and clover. Monitor your lawn’s health and apply a second treatment if new weeds sprout up mid-summer.

  • Pre- and post-emergence crabgrass control
  • Visible application with blue dye
  • Allows spring overseeding
  • Also targets broadleaf weeds
  • Expensive compared to other pre-emergents
  • Requires heavy rainfall after application
  • Less effective on broadleaf weeds than selective herbicides

The Andersons Barricade Insecticide

Now that we’ve covered Dimension Two Herbicide from Bayer, our review turns to The Andersons Barricade Insecticide. This pre-emergent herbicide is also designed to prevent weeds before they sprout, with the active ingredient prodiamine making up 0.

The granular product comes in an 18-lb bag designed to cover up to 5,800 square feet of lawn.

Barricade excels at preventing tough weeds like crabgrass and goosegrass. The granules are convenient for homeowners to spread without any spraying or mixing. The DG Pro technology enhances the product’s weed prevention capabilities compared to previous versions.

Users do report the best success when applying to an already-weeded lawn, since this herbicide does not kill existing weeds. Some experience minor lawn damage if applied improperly. Success largely depends on following the label’s instructions closely.

  • Prevents many common grass and broadleaf weeds
  • Convenient granular application
  • Provides season-long control
  • Does not kill existing weeds
  • Potential for lawn damage if misapplied
  • Less effective on some weeds like dandelions

You’ll appreciate how the natural corn gluten in Espoma Organic Weed Preventer nourishes your lawn while preventing dandelions and crabgrass. This 25-pound bag of granules, made from a corn byproduct, provides an organic and eco-friendly way to inhibit the root development of emerging weed seeds.

Simply apply the granules twice yearly in early spring and fall at the recommended rate of 25 lbs per 1,250 sq ft. The nitrogen in the formula feeds your grass for a thicker, greener lawn. And the weed prevention is safe for children and pets after application, unlike synthetic herbicides.

Users mention noticeable improvements in lawn color and reduced dandelions without the work of hand weeding. While effective for common lawn weeds, it does not prevent weeds in flower beds.

  • Organic and safe formula
  • Improves lawn thickness and color
  • Prevents common lawn weeds
  • Easy granular application

The flip-top applicator allows you to easily target problem areas in your flowerbeds, around trees, and shrubs. When used properly, a single application keeps weeds like dandelions and crabgrass from sprouting and robbing your plants of vital nutrients.

While it may be a bit pricier than some competitor brands, the 6-month protection makes it well worth it for most gardeners and landscapers, saving hours of labor pulling stubborn weeds.
