Odessa Herbicide – Post-Emergent Weed Control for Tough Weeds

Odessa Herbicide is designed to tackle some of the toughest broadleaf and grass weeds in home lawns. It offers targeted, post-emergent control over a range of hard-to-kill weeds that many other herbicides struggle with, including:

• Bindii

• Guildford Grass (Onion Grass)

• Onion Weed (False Onion Weed / Fragrant False Garlic)

• White Clover

• Oxalis

• Mouse Ear Chickweed

• Cudweed

• Cat’s Ear

• Medic

• Cotula

• Black Thistle

Odessa is highly effective on lawns like Common Couch, Hybrid Couch, Buffalo, and Kikuyu. (Note: Do not use on Queensland Blue Couch.)

Why Choose Odessa?

• Excellent post-emergent control of persistent weeds like Guildford Grass and Onion Weed

• Selective control of Ryegrass from Couch, Buffalo, and Kikuyu lawns

• Safe for use on warm-season grasses (excluding QLD Blue)

• Low odour and low toxicity (Schedule 5 – Caution)

• Water-dispersible granule (WDG) formulation

• Trusted Group 2 Herbicide (Iodosulfuron-methyl-sodium 100g/kg)

Best Time to Apply

For best results, apply Odessa when weeds are healthy and actively growing — ideally in Autumn or Spring. You’ll get optimal control when daily temps reach 18–21°C or higher.

Avoid using during cold winter periods when daytime temps stay below 15°C, as this can reduce effectiveness.
