Key benefits
- Controls 16 broadleaf weeds up to 8 leaves and 4 grass weeds up to 3 tillers
- Mix with atrazine, clopyralid, dicamba or nicosulfuron to extend the weed spectrum
- Proven reliability provided spray coverage is adequate
How it works
Arietta® contains topramezone, a herbicide from the HPPD (4-hydroxyphenylpyruvate dioxygenase) mode of action group – classified as Group F2.
Arietta is taken up by both leaves and roots, and transported within the plant, where it interferes with the synthesis of carotenoids. This leads to bleaching (chlorosis) of leaves and weeds typically die within 14 days of treatment.
Although Arietta is systemic, thorough coverage of the target weed is necessary for optimum results. Application to small, actively growing weeds when conditions are conducive to maximum photosynthesis (moist, warm, bright sunshine) is ideal.

Questions and Answers from the Field
-
Why use Arietta?
- Flexibility in application timing
- Weed spectrum
- Reliability
- Broadleaf weeds (up to 8 weeds)
- Grass weeds (up to 3 tillers)
-
Which oil or adjuvant is best to use with Arietta?
Hasten™ oil must be used with Arietta (esterfied canola oil). Hasten provides Arietta with the most effective penetrant system.
-
What is the application rate?
Arietta 200 mL/ha + atrazine 1L/ha + Hasten 500 mL/100 L of water
-
What are the tank mixing options for Maize to extend weed spectrum?
- Atrazine - Enhances Arietta performance on labelled weeds
- Nicosulfuron (WG formulations only) - Ryegrass and couch (twitch)
- Clopyralid - Californian thistle, yarrow and volunteer potatoes
- Dicamba - Californian thistle, field bindweed (Convolvulus arvensis) and cornbind (Polygonum convolvulus)
NOTE: Do not use dicamba, clopyralid or nicosulfuron mixtures on sweetcorn
