Neudorff’s WeedFree Plus is a complete herbicide for both weeds and grasses. It works against a wide variety of annual and perennial weeds and is also effective against stubborn weeds, e.g. Stinging nettle, Dandelion, Thistle, Chickweed, Bluegrass, Field horsetail, Plantain and Ground Elder / Goutweed. The unique combination of two active ingredients, pelargonic acid and maleic acid hydrazide, create a weedkiller that is both fast-acting and long-lasting against weed regrowth. Pelargonic acid is also found naturally in pelargoniums and is a highly effective fatty acid widely used in the treatment of unwanted plants. Maleic acid hydrazide is an extremely old and well researched active ingredient. First produced in 1895, it has been used as a growth regulator in crop management since 1952. Its main applications have been in the production of food, particularly being used on potatoes and onions as an anti-sprouting agent.
Available as a ready to use spray or a concentrate.
