What is the best killer for Japanese knotweed?
The most effective and widely used herbicide for controlling Japanese knotweed is glyphosate.
Glyphosate-based herbicides are systemic, meaning they are absorbed by the plant and translocated throughout it, including its extensive root system (rhizomes). This characteristic makes glyphosate highly effective in targeting and killing Japanese knotweed.
When using glyphosate herbicides to control Japanese knotweed, it’s essential to follow these guidelines:
- Professional Application: Glyphosate herbicides should be used by licensed professionals who are experienced in dealing with invasive plants like Japanese knotweed. They will know the right timing and application techniques to maximise effectiveness.
- Timing: The best time to apply glyphosate to Japanese knotweed is during the plant’s active growth phase, typically in late summer or early autumn, when it moves nutrients to its underground rhizomes.
- Multiple Applications: Controlling Japanese knotweed usually requires multiple herbicide applications over several years. The rhizomes can be persistent, so follow-up treatments are necessary to ensure successful eradication.
- Site-Specific Considerations: Glyphosate herbicides should be applied carefully to avoid damaging non-target plants nearby. Specialists will consider site-specific factors to minimise environmental impact. What is the best killer for Japanese knotweed?
Glyphosate herbicides work by inhibiting a crucial enzyme involved in synthesising certain amino acids (the building blocks of proteins) in plants. The enzyme targeted by glyphosate is called EPSP synthase (5-enolpyruvylshikimate-3-phosphate synthase).
Injecting Japanese knotweed Stems
Here’s how glyphosate kills the plant:
Absorption and Translocation:
When glyphosate is applied to the plant’s leaves, it is absorbed and translocated throughout the plant’s vascular system. The herbicide then moves down to the roots, where the critical metabolic processes take place.
Inhibition of EPSP Synthase:
Glyphosate interferes with the action of EPSP synthase, an enzyme essential for producing three specific amino acids: phenylalanine, tyrosine, and tryptophan. These amino acids are crucial for synthesising plant growth and development proteins.
Starvation of the Plant:
As EPSP synthase is inhibited, the plant cannot produce the three essential amino acids. Without these amino acids, protein synthesis is disrupted, and the plant’s ability to grow and maintain crucial cellular functions is severely compromised.
Cell Death and Plant Desiccation:
The lack of protein synthesis disrupts cell division and cell growth, ultimately resulting in the death of plant tissues. The plant gradually becomes desiccated, losing water and withering as it dies.
Systemic Action:
One of the key features of glyphosate is its systemic action, which means it is translocated throughout the entire plant. This allows the herbicide to reach even the underground rhizomes of plants like Japanese knotweed, ensuring effective control.
Due to its systemic nature, glyphosate is highly effective at targeting and killing many plants, including many weeds. However, its effectiveness is not limited to invasive plants like Japanese knotweed, making it a valuable tool in weed control when used responsibly and according to the manufacturer’s instructions.
Spraying knotweed?
It’s important to note that while glyphosate is effective, it should only be used by licensed professionals trained in safely handling and applying herbicides. Unregulated or inappropriate use of herbicides can adversely affect the environment and human health.
Suppose you are dealing with Japanese knotweed on your property or in your area. In that case, it is best to seek advice and assistance from experts in invasive plant management to develop a comprehensive control plan that may include glyphosate-based herbicides and other appropriate methods.
