Time Apply when the buttercup is growing well. Site of action (diflufenzopyr) Group 19: inhibits indoleacetic acid transport (dicamba) Group 4: synthetic auxinĬhemical family (diflufenzopyr) Semicarbazone (dicamba) Benzoic acid Do not exceed 10 oz/A of Overdrive per season. Remarks For improved uptake if weeds are under moisture or temperature stress, use a nonionic surfactant or a methylated seed oil.Ĭaution Do not plant any crop within 30 days of application. Site of action (aminocyclopyrachlor) Group 4 synthetic auxin (chlorsulfuron) Group 2: ALS inhibitorĬhemical family (aminocyclopyrachlor) Pyrimidine carboxylic acid (chlorsulfuron) Sulfonylurea Can injure several grass species including bromes, as well as basin wildrye. Can be applied using an invert emulsion rather than water.Ĭaution Even low rates can kill nontarget tree and shrub species, so avoid application within a distance equal to the tree height of the sensitive species. Remarks Adjuvants can be used these include methylated seed oils 0.5 to 1% v/v, nonionic surfactants at 0.25 to 1% v/v, and crop oil concentrates at 1% v/v. Time Apply to actively growing vegetation. Rate 1.2 to 1.8 oz/A aminocyclopyrachlor + 0.5 to 0.7 oz/A chlorsulfuron (3 to 4.5 oz/A of product) 326, 328.Aminocyclopyrachlor + chlorsulfuron (Perspective) Institute of Irish Studies and The Queen's University of Belfast ISBN 0-85389-446-9. ![]() Stewart and Corry's Flora of the North-east of Ireland. ^ Flora of NW Europe: Ranunculus repens.^ Buttercups focus light to heat their flowers and attract insects New Scientist 25 February 2017."Functional optics of glossy buttercup flowers". 1825 Suppl., Sitfast, Creeping Crowfoot, Ranunculus Repens. The plants restharrow and creeping crowfoot. ^ Oxford English Dictionary entry for "Sit-fast":2.Agricultural Research Service (ARS), United States Department of Agriculture (USDA). Germplasm Resources Information Network (GRIN). Repens means 'creeping' or 'stoloniferous'. This name is in reference to the amphibious habitat of many Ranunculus species. Ranunculus is a diminutive of 'rana', meaning 'little frog'. Contact with the sap of the plant can cause skin blistering. Creeping buttercup also is spread through the transportation of hay. The plants then take advantage of the cropped ground around it to spread their stolons. The taste of buttercups is acrid, so cattle avoid eating them. Like most buttercups, Ranunculus repens is poisonous, although when dried with hay these poisons are lost. Cultivation and uses Ĭreeping buttercup was sold in many parts of the world as an ornamental plant, and has now become an invasive species in many parts of the world. In Ireland: very common in damp places, ditches and flooded areas. It is a very common weed of agricultural land and gardens, spreading quickly by its rooting stolons and resisting removal with a deeply anchored filamentous root ball. ![]() It grows in fields and pastures and prefers wet soil. Creeping buttercup has three-lobed dark green, white-spotted leaves that grow out of the node. ![]() The fruit is a cluster of achenes 2.5–4 mm ( 3⁄ 32– 5⁄ 32 in) long. The gloss is caused by the smooth upper surface of the petal that acts like a mirror the gloss aids in attracting pollinating insects and thermoregulation of the flower's reproductive organs. ![]() The flowers are golden yellow, glossy, and 2–3 cm ( 3⁄ 4– 1 + 1⁄ 4 in) diameter, usually with five petals, and the flower stem is finely grooved. Both the stems and the leaves are finely hairy. The leaves higher on the stems are smaller, with narrower leaflets and may be simple and lanceolate. The basal leaves are compound, borne on a 4–20 cm ( 1 + 1⁄ 2–8 in) long petiole and divided into three broad leaflets 1.5–8 cm ( 1⁄ 2– 3 + 1⁄ 4 in) long, shallowly to deeply lobed, each of which is stalked, distinguishing the species from Ranunculus acris in which the terminal leaflet is sessile. It has both prostrate running stems, which produce roots and new plants at the nodes, and more or less erect flowering stems. It is a herbaceous, stoloniferous perennial plant growing to 50 cm (20 in) tall.
