Turf Culture Spartan Pre-Emergent Herbicide Prodiamine

Group 3 Herbicide

Spartan Herbicide’s selectivity is primarily through soil profile placement. Achieving this soil profile placement of the herbicide correctly is vital to obtain high efficacy. Applicators should ensure an even matrix flow through the soil profile to achieve a consistent and even zone of herbicide activity (see graphic below).

After application, plants which have the majority of their root system in the herbicide profile zone cannot effectively absorb the water and nutrients required for root and plant development. Therefore good even coverage and incorporation is required to ensure the weeds cannot recover by establishing roots outside the zone of herbicide activity.

Small seeded plants (i.e. annual grass weeds) are affected more by the herbicide than established grasses and plants as they germinate in the soil profile zone of herbicide placement (i.e. 100% of their germinating root system is affected by the herbicide).

Warm season grasses and established Garden & Potted Plants can be less prone to root inhibition due to the fact that they have multiple fibrous root systems with established roots beyond the depth of the zone of herbicide activity and are therefore are still able to obtain moisture and nutrients. 

Key Benefits:

• Effective against all major annual grass weeds in turf, garden beds & potted plants during summer and winter
• Season-long control of annual weeds
• Reduces future weed set and germination
• Reduces the reliance on costly selective post-emergent herbicides
• Unscheduled (exempt from poison scheduling) Selectivity 
• Minimises nutrient and sunlight competition from annual grasses
• Application compatibility with wetting agents
• Low odour formulation 
• Economical solution for your main annual weed problems including African Lovegrass, Parramatta Grass, Summer Grass, Crab Grass, Crowsfoot Grass and Winter Grass
• Flexibility to delay wash-in in turf for a few days if necessary 
• Pack sizes available: 250mL & 500mL (Home Garden), and 10L (Commercial)

Maximising Performance:

• Soil Preparation: Areas to be treated should be free of established weeds.
• Apply prior to germination of weeds.
• Apply at a water volume not lower than 500 L/ha per hectare (5 L per 100 m2).
• An addition of a soil penetrant is recommended to ensure an even matrix flow through the soil profile.
• The addition of crop oil concentrate may result in crop injury and reduced compatibility in the spray tank.
• Applications to Turf should be incorporated by 6 mm of spray irrigation or rainfall as soon as possible, at least within 7 days after application.
• Applications to Garden Beds & Potted Plants should be incorporated by 3 mm of spray irrigation or rainfall immediately after application.
