This disease can significantly impact the appearance and aesthetics of boxwood because the foliage typically becomes blighted and drops from the plant. Symptoms of box blight include: dark‐ or light‐brown, circular leaf spots often with darker margins; dark stem cankers or black ‘streaks’ on stems; straw‐ to bronze‐ colored, blighted foliage; and leaf drop. Leaf spots may grow together to eventually cover the entire leaf (see pictures). In container boxwood, sometimes only the lower foliage and stems become infected, leaving the tops green and making the plant appear top‐heavy.On large field‐grown or landscape plants only one section of the plant closest to the ground on the shaded side will be blighted.

Marengo is registered for use on production ornamentals grown in outdoor nurseries, as well as on conifers, Christmas trees, and ornamental production sites and hardscapes. Marengo is labeled for use in shade houses and hoop houses as well.

Marengo offers extended broad-spectrum weed control of up to eight months in nurseries but also in extended use sites such as hardscapes and hoop houses,” notes Dave Barcel, OHP senior technical manager. “It’s extremely active at low use rates.

Marengo use rates range from 7.5 to 18.5 fl.oz. per acre depending on soil type and conditions.  It performs best when applied to bare ground or mixed with a post-emergent herbicide to eliminate existing weeds.

Marengo should be applied as a broadcast spray over ground areas and as a directed spray for field grown ornamentals.  Fall applications have shown excellent weed control through the following spring season.

Marengo will be packaged in one-half gallons, packed 4 to a case.
