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.)
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)
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.
