Contra M Herbicide Weed Killer

Contra M Duo Herbicide – Broadleaf Weed Control for Lawns

Fast, broad-spectrum weed control made easy.
Contra M Duo is a selective herbicide that takes out the toughest broadleaf weeds in turf and non-crop areas — including Bindii, Clover, Creeping Oxalis, Capeweed, Plantain, Cudweed, Dandelion, and Thistle species. It combines MCPA (340 g/L) and Dicamba (80 g/L) in a low-odour, amine formulation that’s safe, reliable, and easy to use across most turf types. Contra M is not suitable for Buffalo Lawns (try Bow and Arrow instead)

Formulated as a Group I systemic herbicide, Contra M Duo mimics natural plant hormones to disrupt weed growth from the inside out. You’ll see visible signs of twisting and yellowing within 7–14 days as the weeds die off completely.

How much to apply:
Mix 100 mL per 100 m² in 15 L of water for home lawns, or 6.5 L per hectare for large turf areas. Apply evenly over actively growing weeds on a calm, dry day. Avoid mowing 2 days before or after spraying, and do not irrigate for at least 4 hours.

Contra M Duo provides one of the broadest spectrums of control on the market and is ideal for kikuyu, couch, buffalo, ryegrass, and mixed lawns when used according to label directions.
