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.
