Syngenta Acelepryn
Acelepryn uses chlorantraniliprole to control grubs and other pests, like Japanese beetle and gypsy moth caterpillars. Syngenta notes that early applications of Acelepryn provides season-long control against white grubs and caterpillars, and excellent protection against billbugs and weevils. The product has low water solubility, so later applications should be watered in to help with uptake.

Acelepryn is approved for use on lawns and landscapes, golf courses and sod production, as well as sports turf. It mixes well with Barricade herbicide (see below), according to Syngenta, and can be applied to leaves, soil, bark and in broadcast sprays. Testing has found little adverse effect on beneficial insects like honeybees and earthworms.

Drive XLR8 is a new formulation of Drive 75 DF to help control crabgrass and other weeds. It uses a proprietary water-based formulation that provides quicker uptake by plants and is rain-fast in under an hour.

BASF notes that Drive is even effective on mature crabgrass, including grass with four tillers or more. A single application can provide residual control for up to 45 days. It can be tank-mixed with other pre- and post-emergent grass herbicides, and with post-emergent broadleaf herbicides. BASF recommends not mowing for the two days before and after application.

Freehand 1.75G
Freehand is a pre-emergent herbicide that protects against a wide range of weeds in landscape ornamentals. Freehand uses two active ingredients—dimethenamid-P and pendimethalin—to control barnyardgrass, crabgrass, foxtail and goosegrass, among other weeds. It’s labeled for use in maintained and noncrop areas, including container, liner and field commercial nurseries, as well as forest nurseries.

Some ornamental plants are especially sensitive to Freehand, including blue fescue, columbine and phlox.

Syngenta Barricade 65WG and 4FL
Barricade 65WG and 4FL are pre-emergent prodiamine-based herbicides that provide season-long protection against over 30 weeds, including barnyardgrass, crabgrass and goosegrass, according to Syngenta. Barricade can be applied in the fall to help prevent weed growth in the spring.

Barricade 4FL is a liquid herbicide, and can be used on established turf and plantings, sod nurseries, ornamentals and Christmas tree farms. Barricade 65WG is available in a water-dispersible granule. It can be mixed with fertilizer, and is labeled for a wider range of sites, including conifer and hardwood seedling nurseries. Syngenta notes that both 65WG and 4FL should not be used on putting greens.

Both 65WG and 4FL can be mixed with post-emergent herbicides to help treat established weeds. Treated areas should be irrigated within 14 days of application.

Additionally, Syngenta offers a guarantee on Barricade’s effectiveness against crabgrass. For more on that program, visit greentrust365.com.
