A weed can be defined simply as a plant growing where it’s not wanted. An agronomic view would add that weeds compete for water, light and space with desirable plants, and can harbor diseases and insects. But to a homeowner, and your customer, weeds diminish the aesthetic value of their lawn and landscape plantings.

Importance of pre-emergent control
Weed control for lawn and landscapes should include a pre-emergent like Barricade^® brand herbicide to prevent the development of weed seedlings. This is particularly important for grass weed control as there are few options for post-emergent grass control. Depending on turf type, Tenacity^® and Manuscript^® herbicides also have pre- and/or post-emergent activity on certain grass weeds in landscape beds, woody and herbaceous plants that can be sensitive to post- emergent herbicide applications. Barricade 4FL and Tenacity are available in convenient 4-oz. and 8-oz. bottles.

Reward^® herbicide in landscape beds (and edging) offers fast burn down of grass and dicot weeds, prevent contact with desirable plants, without staining concrete, volatility, or movement from the application site. It disrupts photosynthesis and can be applied as a broadcast spray or for spot treatments.

Reward is a contact, non-selective herbicide that disrupts photosynthesis, causing degradation of cell walls within hours, burning all the foliage it contacts. It can be applied as a broadcast spray or in a backpack sprayer for spot treatment applications at 0.75 oz./gal. All applications will need a non-ionic surfactant to enhance plant surface coverage. Additional uses include:

• Weed control in joints and edges of hard surfaces around the landscape
• Winter weed control such as Poa annua in dormant turf
• Burn down of existing bermudagrass turf prior to overseeding with ryegrass for winter color

​​​​​​​Fusilade^® II Turf and Ornamental herbicide will stop growing within a week after application, although control may take two to three weeks. Fusilade II is a grass herbicide and is safe to use around ornamental plants and on fine fescue turf. The spot treatment rate for Fusilade II in landscape beds, fence lines and non-turf areas is 0.75 oz. per gal. Poa annua and fine fescue are naturally tolerant to Fusilade II.

Fusilade II and Reward can be tank mixed together (at 0.75 oz./gal. of each herbicide plus a non-ionic surfactant) to enhance control of perennial grass weeds (such as bermudagrass, bentgrass, quackgrass, etc.) in landscape beds and other non-turf areas.
