Unfortunately, due to oryzalin molecule shortages world-wide, Embargo is unavailable indefinitely. Hopefully, it will be back on the market at some stage, but it will not be this calendar year (2021).

Turf Culture was aware of the pending Embargo molecule shortages in early 2017 and started the development of Spartan Herbicide.

Spartan Herbicide is the perfect alternative to Embargo Herbicide.

Spartan’s active constituent is PRODIAMINE.

PRODIAMINE is a member of the same chemical family as Embargo (ORYZALIN), the Dinitroaniline family. Hence Embargo & Spartan share the same Mode of Action, which is the way they work and provide pre-emergent weed control.

Spartan will give you the same reliable pre-emergent control as Embargo, with longer weed control options. Expect 6+ months pre-emergent control when applying Spartan at 3 litres per hectare (or 30mL per 100m2).

Spartan Herbicide is available now.

For pre-emergent control of certain annual grasses and broadleaf weeds in Turf.

Embargo Herbicide is a pre-emergent herbicide that can be used as an effective tool to help Turf Managers control annual weeds (Summer & Winter).

Embargo Herbicide selectivity is primarily through soil profile placement. Small-seeded plants take up greater amounts of the herbicide as they germinate in the soil profile zone of herbicide placement. Warm Season grasses can be less prone to root inhibition due to the fact they have a multiple fibrous root system, hence good even coverage and incorporation is required to ensure the weeds cannot recover by establishing roots outside the zone of herbicide activity.

Application should be prior to germination of the weeds; Winter Annuals - usually from late summer to mid-autumn, February to May. Summer Annuals - usually from early spring to summer, September to December.

Poison Schedule - Non Scheduled (Unscheduled)
