Burn down broadleaf weeds at record speeds
Sharpen® is a fast-acting broadleaf herbicide for pre-emergence use in maize and sweet corn crops, pre-plant burndown when tank mixed with glyphosate in seedbed preparation and conservation tillage and general weed control in apple and pear orchards and non-crop situations.
Sharpen provides excellent control of major broadleaf weeds including triazine-resistant chickweed, willow weed, nightshade and fathen. Tank-mixing with pre-emergence herbicides in maize also broadens the spectrum of activity.
Sharpen® is a Group E PPO (protoporphyrinogen-IX-oxidase) mode of action herbicide. It is rapidly absorbed through the roots and foliage of plants. Within a few hours following application, the foliage of susceptible weeds shows signs of desiccation, and in subsequent days necrosis and death. Extremes in environmental conditions (temperature and moisture), soil conditions and cultural practices may affect the activity of Sharpen. Under warm, moist conditions herbicide symptoms may be accelerated. Under very dry conditions the expression of herbicidal symptoms is delayed, and weeds hardened off by drought are less susceptible to Sharpen.
