This information is not designed to be specific but to raise

herbicides. Here at London Japanese Knotweed Removal we provide detailed information on how we will tackle your Knotweed problem.
The use of herbicides is often the most effective option for the control of Japanese Knotweed but there are issues that London Japanese Knotweed Remova feel need to be considered first.
There are Health and Safety issues and those administering herbicide need to be properly trained and hold a Certificate of Competence. Herbicides should only be used in accordance with the advice on the label otherwise it is considered an offence. It is also an offence to use products that are not approved. Check that the herbicide formulation is approved for the intended use. Furthermore there is an obligation to avoid the spread of herbicide to non-target areas so spraying needs to be carried out in dry weather (no rain for 6 hours, preferably 24), spraying should also not be carried out in wind speeds above Force 2 on the Beaufort Scale to avoid spray drift.

Japanese Knotweed can become very tall which makes it difficult to apply herbicides. The plants should ideally be sprayed in the spring when they are about 1m tall or after cutting when they have re-grown to this height. There are various methods of application including tractor-mounted spraying for large areas; knapsack spraying for small areas; lance sprayer for tall stands or for stands in inaccessible places (such as steep slopes and river banks); controlled droplet applicaton; injection method for small stands and weed wiper or herbicide gloves for direct application onto leaves of specific plants.
Here at London Japanese Knotweed Control our preffered method of control is the use of Glyphosate. Dense stands of Japanese Knotweed can be treated with a
glyphosate-based herbicide. Glyphosate
is a systemic herbicide which acts by blocking a plant’s enzyme system.
The herbicide is absorbed through growing leaves and stems where it is
translocated throughout the plant and root network. It kills virtually
all annual and perennial weeds including grasses. Glyphosate is quickly
broken down in soil or sediment and is harmless to animal life. Not all
formulations containing Glyphosate are approved for use in or near
watercourses under the Control of Pesticides Regulations 1986. Commercial quality Glyphosate is only available to commercial contractors and is significantly stronger than high street porducts
