There is no quick solution for the eradication of Japanese knotweed. As long as you are willing to invest the effort and follow a few key timing guidelines, it can be successfully controlled. Aquatic Invasive Species Contacts. In comparison to native streamside vegetation, Japanese knotweed provides poor erosion control, and its presence gradually degrades aquatic habitat and water quality. Large colonies frequently exist as monocultures, reducing the diversity of plant species and significantly altering natural habitat. Its close relative, giant knotweed (Fallopia sachalinensis), is very similar in appearance and ecology, and the two species form the hybrid bohemian knotweed (Fallopia × bohemica). Improper timing will result in treatments that provide “topkill" (shoot injury) but little net effect. It is found near water sources, such as along river banks, low-lying and disturbed areas. Reproduction from rhizomes (horizontal underground stems), even small fragments, enables the plant to b… The dense, low canopy formed by a thicket of tangled stems and large leaves creates a monoculture, excluding nearly all other vegetation. (15.2 cm) … Japanese Knotweed (Mexican bamboo) Fallopia japonica.

Bugwood.org. The herbicide imazapyr (e.g., Polaris, Habitat) is also effective against knotweed, but it has considerable soil activity and can injure nearby trees through root uptake. Typically, knotweed regrows to 2 to 5 feet tall during the eight-week window after cutting, but this waiting period is critical—if you apply herbicide too soon after cutting, the herbicide will not be effectively translocated to the rhizomes. This plant thrives on most sites that are at least seasonally wet. In Australia, it is illegal to have any of this species growing on your property. Fallopia japonica, commonly known as Japanese knotweed, is a large, herbaceous perennial plant of the family Polygonaceae, native to East Asia in Japan, China and Korea.In North America and Europe the species is very successful and has been classified as an invasive species in several countries. Photo by Dave Jackson, Stem showing nodes. These weeds displace native plants, destroy critical fish and wildlife habitat, and reduce recreational opportunities. The stems have a fine white coating that rubs off easily. Japanese knotweed was probably introduced into the United States in the late 1800s. Rhizomes are creeping underground stems that give rise to new shoots and roots. Product names reflect the current Pennsylvania state herbicide contract; additional brands with the same active ingredients are available. Japanese knotweed commonly invades disturbed areas with high light, such as roadsides and stream banks. It was introduced to North America in … Fallopia japonica (=Polygonum cuspidatum) (Japanese knotweed) is a perennial forb/herb (family Polygonaceae). The semi-woody stem is hollow with enlarged nodes. 2019 Status in Maine: Widespread. There are two phases of knotweed management: initial control and maintenance. Cutting in June results in shortened regrowth (2 to 5 feet) and elimination of persistent stems from the previous season. Cutting is also useful when knotweed is growing near water because it is easier to treat the shorter regrowth without inadvertently spraying herbicides into the water during follow-up treatments. Applications of Aquaneat will require an additional surfactant (e.g., CWC 90). Photo by Dave Jackson. Growing up to 11 feet tall, knotweed can spread horizontally via an extensive network of underground rhizomes, along which many shoots will sprout. Fallopia japonica. Evidence for massive clonal growth in the invasive weed Fallopia japonica ML Hollingsworth, JP BAILEY – Botanical Journal of the Linnean …, 2000 – academic.oup.com Clonal growth in introduced populations of Japanese Knotweed (Fallopia japonica) in Britain was assessed using RAPDs (Randomly Amplified Polymorphic DNA). • It is listed under schedule 9 of the Wildlife and Countryside Act 1981 and it is an offence to plant or cause this species to This article will assist with identification and provides recommendations for control, including a management calendar and treatment and timing table. Local Concern: Japanese knotweed grows very aggressively in disturbed areas. As long as you are able to effectively spray all the foliage, cutting is not critical. Full sun conditions are preferable, although this plant can tolerate some shade and a wide range of soil and moisture conditions. 2019 Status in Maine: Widespread.Severely Invasive. Combinations with triclopyr or imazapyr provide a broader species spectrum and do not reduce activity against knotweed. Japanese Knotweed Invasive Species Alert - Printable PDF. Japanese knotweed is a Class B Noxious Weed in Washington, first listed in 1995. Invasive Species - (Fallopia japonica) Prohibited in Michigan Japanese knotweed is a perennial shrub that can grow from 3 - 10 feet high.

Japanese knotweed (Fallopia japonica) was brought from eastern Asia as a garden plant. Invasive Knotweeds: Japanese, Giant, Bohemian & Himalayan (Fallopia japonica, Fallopia sachalinensis, Fallopia x bohemica & Polygonum polystachum) Knotweed Species are found throughout communities on Vancouver Island, the Gulf Islands and the Sunshine Coast. These widespread and highly negative effects should be considered alongside any argument for its overall value. Prescriptions for controlling knotweed stress proper timing of operations to maximize injury to rhizomes. Use this treatment for both initial control and follow-up maintenance applications. It reduces plant diversity and can increase shoreline erosion. Cut in June and wait at least eight weeks after cutting to treat the resprouting plants with herbicide; knotweed regrowth will be much shorter than if it had not been cut, and the rhizomes will be forced to redirect their energy reserves toward resprouting instead of expanding their underground network. F. japonica is an extremely invasive weed despite its lack of extensive sexual reproduction in most of its introduced range. In its native Asia, knotweed has many applications in traditional herbal medicine. If you work at the early end of the operational window, you can make a touch-up application later in the season before a killing frost. Removing Japanese knotweed. Japanese knotweed ( Fallopia japonica ) is a weed that spreads rapidly. Fragments can be dispersed along waterways during flooding events or by the movement of soil containing root fragments.

Characteristics, Effects, and Controls . In winter the plant dies back to ground level but by early summer the bamboo-like stems emerge from rhizomes deep underground to shoot to over 2.1m (7ft), suppressing all other plant growth. Another nonnative but not aggressively invasive species, broad-leaved dock (Rumex obtusifolius), could also be confused with young knotweed shoots, but broad-leaved dock consists of a rosette of many basal leaves emerging from a central taproot, differentiating it from Japanese knotweed's many single, rapidly elongating stems.
