Odessa Herbicide – Post-Emergent Weed Control for Tough Weeds

• White Clover

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.
