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 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 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.
