Arsenal® Super
Advanced control of unwanted vegetation for up to six months
Mode of action: Group 2 herbicide
Active ingredient(s): 240 g/L Imazapyr present as the isopropylamine
Formulation: Soluble concentrate (SC)
Arsenal® Super is the latest, optimised formulation of a proven herbicide solution for non-crop situations where long-term vegetation management is required. Arsenal Super will keep a very wide range of grass and broadleaf weeds controlled for up to six months along fence lines, firebreaks, irrigation channels, rights of way, roadside verges and railways. It can also be used around commercial, industrial and agricultural buildings. Most effective as a standalone solution when used on bare earth or newly emerged weeds, Arsenal Super can be tank-mixed with glyphosate and other knockdown herbicides to control larger plants.
Key benefits
- 6 months + residual control
- Strengthen existing IWM strategies
- Pre and post emergent control
How it works
Arsenal® Super is an aqueous solution that will kill a range of standing weeds and emerging seedlings. It stops growth rapidly, although symptoms may take over 30 days to develop. Affected plants are discoloured and often growth is distorted. The active material in Arsenal is rapidly absorbed through foliage and roots, and translocated throughout plants. Foliage treatments will provide pre-emergent control as the active material is released to the soil following plant decay. Residual control of weeds, for which the lower rate of Arsenal is recommended, will increase when the higher rate is used.

Situational Use Pattern – Nursery & Surrounds
Arsenal Super offers a diverse use pattern around fixed nursery structures, fence lines, and under seeding/planting tables, where long-term weed control is imperative. Applications can be made pre- or post- emergence via handgun or knapsack. Arsenal Super stops growth rapidly although symptoms may take over 30 days to develop. Affected plants are discoloured and growth is distorted. Arsenal Super is rapidly absorbed through foliage and roots and translocated throughout the plants.
Do not use where water will be collected for irrigation, or in areas where potted plants roots will be in contact with treated surfaces.
