Chemical group & mode of action - Avadex Triflurx

Chemical group & mode of action



The active ingredient in Avadex is triallate, an inhibitor of fat synthesis and member of the thiocarbamate chemical family (Group J).

Triallate is effective in inhibiting cell division and elongation in the seedling shoots before emergence from the ground, and causes abnormal emergence of leaves from the coleoptile. The growth of susceptible weeds is inhibited and plants exhibit cupped or crinkled leaves. Uptake is through the seed, shoots and roots where the shoots are more affected than the roots. Under the Australian Herbicide Resistance Management System, these herbicides currently carry a moderate resistance risk.

The active ingredient in TriflurX is trifluralin, an inhibitor of microtubule assembly and member of the dinitroaniline family of chemistry (Group D).

Trifluralin is effective in inhibiting cell division by disrupting the formation of tubules in cells that are dividing. It does not stop a seed germinating. It is absorbed by the roots and shoots of susceptible weeds, symptoms are largely unseen as they occur below the ground. Under the Australian Herbicide Resistance Management System, these herbicides currently carry a moderate resistance risk.
