Envu Solutions – Wild chervil
Wild chervil (Anthriscus sylvestris), also referred to as wild parsley or cow parsley, is a troublesome weed that has successfully invaded roadsides, ditches, pastures, forest edges and dykes in various areas throughout North America. It prefers disturbed sites with rich, moist soils and can persist under partial shade.
Native to Europe, wild chervil was introduced to North America in wildflower seed mixes. In Canada, wild chervil can be found on the west coast of British Columbia, Ontario and the east coast of Nova Scotia, Newfoundland, New Brunswick and Quebec.
Apply herbicides early, shortly before blooming or a month after pre-bloom cutting.
Applying Navius® FLEX to small chervil plants – preferably when they are 10–15 cm tall – can improve control. If chervil plants are taller than 15 cm, or for heavy infestations, effective control requires complete spray coverage of the foliage. Use application equipment that gives the best coverage of all chervil plants while minimizing spray drift. Remember, taller plants, railroad ties, guardrails, and other obstacles can shield or shadow smaller plants and limit contact with shorter chervil plants that are targeted for control.
Late summer or fall control of wild chervil rosettes is effective as long as the plants are still green. In late summer and fall, photosynthates are moving to the root, which is an advantage for root control with many foliar herbicides. Using herbicides with residual control is essential to prevent the germination of seedlings after treatment and will also prevent seed production the following year. After control, the establishment of competitive cover is important to prevent new infestations.
Cleaning equipment after herbicide application to a site, mowing, ditching, or any other work on infested sites will help to prevent linear spread down rights-of-way.
