Cortex Duo Industrial Herbicide

Active Ingredients: Nonanoic Acid @ 525g/L & Oxyfluorfen @ 15g/L

Cortex Duo Industrial Herbicide is for the non-selective residual control of seedling and young broadleaf and grass weeds, suppressing established weeds and perennial species, and controlling moss and algae. Cortex Duo is an industrial herbicide recommended for use in commercial, industrial, orchard, vineyard and forestry situations.

Why choose Cortex Duo Industrial Herbicide;

Perfect for knockdown and residual weed control where Glyphosate is not wanted (e.g. Playgrounds, Local government locations where they have a non-glyphosate policy).
It is ideal for knockdown and residual weed control around tree bases & under drip lines.
Excellent for spot treatment of weeds (plus residual control) in garden beds (great safety around established ornamental plants).
It is ideal for knockdown and residual weed control around Fencelines and Furniture (avoids the need for brush cutting). Cortex Duo doesn’t creep like glyphosate, so it is ideal for applications where creep is not desired.
Outstanding for knockdown and residual weed control in nursery production.
Excellent for control of weeds, algae, lichen, liverwort and moss on hard surfaces, gardens & rockeries.

Where can Cortex Duo Industrial Herbicide be used;

Cortex Duo is registered for use in and around paths, driveways, roadsides, sheds, gardens, amenity horticulture areas, protected cropping situations, nearby nursery stock, orchards and vineyards, fallow soils and forestry. It is also registered for the control of Moss and Algae in various situations, including gardens, paths, rockeries, tiled roofs, walls, driveways and around buildings.

Cortex Duo Industrial Herbicide controls seedling and young annual and perennial weeds and grasses, including;

Amsinckia	Common Storksbill	Lichen	Sowthistle
Barnyard Grass	Couch Grass	Liverseed Grass	Stinging Nettle
Bellvine	Crowsfoot	Liverwort	Stink Grass
Camel Melon	Deadnettle	Moss	Stinking Roger
Capeweed	Fat Hen	Peppercress	Urochloa
Carrot weed	Giant Brome Grass	Perennial Ryegrass	Whorled Pigeon Grass.
Chickweed	Groundsel	Pigweed	Wild Radish
Clover	Indian Hedge Mustard	Potato Weed
Common Cotula	Lambs Tongue	Redshank

Cortex Duo Industrial Herbicide contains a non-selective contact herbicide, Nonanoic Acid and a contact residual herbicide, Oxyfluorfen.

Nonanoic acid occurs in plants, including geraniums. It acts on the foliage, causing it to quickly dehydrate and collapse. It works by stripping the waxy cuticle of the weeds, causing cell disruption, cell leakage, and death by desiccation. Results are seen as browning and wilting, usually within hours of application. To be effective, Cortex Duo Industrial Herbicide must come into contact with the green parts of the plant.
Oxyfluorfen provides soil residual control of weeds for up to 3-6 months. Oxyfluorfen targets a specific enzyme, protoporphyrinogen oxidase (PPO), in the chlorophyll pathway. Inhibiting PPO in plants leads to an accumulation of phototoxic chlorophyll precursors, which rapidly disrupt cell membrane integrity in the presence of light. Oxyfluorfen possesses both pre and post-emergent weed control properties.

Q Is Cortex Duo Industrial Herbicide suitable for use on Buffalo lawns? Will it control Bittercress...... Read more
Asked by Jon Ball on August 18, 2024 10:22 am

Answered by the admin
Cortex Duo Industrial Herbicide is a non-selective residual control herbicide. It will wipe out a buffalo lawn and its weeds. It is not suitable for use in domestic situations or the home garden. Although Bittercress and Toothwort are not listed on the product label as weed-controlled, they will likely provide good control if the weeds are seedlings or at an early growth stage.
