ISP ProForce Echelon Duo Advanced Herbicide

Mode of Action

GROUP 14 HERBICIDE

Oxadiazon, one active ingredient in Echelon Duo Advanced is a pre-emergent herbicide, which offers excellent residual performance on key turf weeds in all turf situations. Oxadiazon has a unique mode of action (Group 14) involving shoot absorption rather than root uptake. It interrupts chlorophyll production (a key component of photosynthesis) in the susceptible weed, destroying the new leaves of weed seedlings germinating in the treated soil. As chlorophyll is only in plant leaves, oxadiazon herbicide cannot impact on the root system of the desirable turf species.

GROUP 4A INSECTICIDE

Thiamethoxam, another active ingredient in Echelon Duo Advanced is a systemic insecticide. Thiamethoxam is readily taken up by the foliage and roots and further distributed acropetally (upwards in the plant). Target insects can be controlled by contact action in the soil or via stomach action by ingestion of the active ingredient when feeding on the treated plant material. Thiamethoxam works by blocking nicotinic acetylcholine receptors, preventing acetylcholine from transmitting impulses between nerves, resulting in the target insect’s paralysis and eventual death. Upon ingestion, the target insect stops feeding quickly, limiting further plant attack. 

Maximising performance

• Avoid application when the turf foliage is wet. Apply to a dry leaf to reduce the potential for plant damage.
• Do not use on putting greens, low-cut tees or bowling greens.
• Avoid application to newly seeded turf areas. The preemergent may impact on seed germination.
• Avoid application to fairways/turf surfaces adjacent to natural water bodies.
• Avoid application if heavy rains or storms are forecast within 3 days.
• Apply using a properly calibrated granular applicator which will apply the granules in a uniform pattern. Uniform application is essential for satisfactory weed control. Spreader settings for Scott’s Accupro, Scott’s R8A, Spyker and Vicon are outlined on the label. As each individual spreader varies, therefore use these settings as a guide only.
• Ensure the turf area is free of leaves and other debris, mowing if necessary so that the granules reach the soil surface. Delay reseeding of Ryegrass or Bentgrass into treated areas for 4-5 months (Ryegrass 4 months & Bentgrass 5 months).
• Avoid mowing treated areas until the product has been watered in and turf foliage has dried.
• After application water in with at least 10 mm of sprinkler irrigation. Control of germinating weed seedlings can be expected for up to 10 weeks after application depending on temperature, rainfall, soil type and other factors. If longer control is required a repeat application should be made 7-10 weeks after the initial application.
• Avoid application when daytime temperatures are consistently above 32°C.
• Do not apply on turf containing Carpet Grass (Axonopus spp.), Centipede Grass (Eremochloa ophiuroides) and Dichondra unless some damage is acceptable.
