LockStar Residual Weed Killer 500g

LockStar is a 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. To control weeds that are already present, LockStar can be tank mixed with glyphosate or fatty acid.

LockStar helps to keep areas such as public places and landscapes weed-free and pleasing to the eye through safe and long-lasting results.

LockStar is an excellent product for resistance management as it contains two innovative 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. LockStar is a granule that is dispersible in water.
