Product Description

LockStar is a NEW residual, pre-emergent total herbicide for use on amenity and landscape areas. Using a new & innovative active ingredient, iodosulfuron, LockStar is an excellent residual herbicide that offers effective control over many species of weeds, such as dandelion, white clover, ribwort plantain & black nightshade. When applied prior to germination, LockStar can keep treated surfaces weed-free for up to 4 months!

LockStar is an excellent product for resistance management as it contains two active ingredients with different modes of action. A product containing two active ingredients with differing modes of action allows increased longevity compared to products with only one mode of action.


Key Benefits:

- Controls a broad spectrum of weeds.

- Has a residual effect for up to 4 months.

- Contains the innovative active ingredient, iodosulfuron- the first new weed control active ingredient to be released in the UK for several years.


Our Recommendation:

- Always read the product label before use.

- LockStar is best applied before weeds emerge. Apply a single application per season between February and June. 

- Mix with glyphosate or fatty acids for post-emergence control. 

- For an excellent glyphosate herbicide, take a look at Roundup Pro Vantage 480 5L

- Save money and time and mix with Blue Dye to ensure no areas are missed or overdosed. 

- Always wear protective clothing, such as Chemical Resistant Gloves, when handling LockStar.
