Herbicide Resistance Discussion

Manage Herbicide Resistance

The easiest and most effective way to manage herbicide resistance is to rotate herbicides with different modes of action. New Velocity m3 is like nothing else you’ve ever seen. It is a combination of two new innovative active ingredients, thiencarbazone-methyl (Group 2) and pyrasulfotole (Group 27); and bromoxynil (Group 6). Together, these three actives provide a “One Solution” product to manage herbicide resistance for farmers growing spring and durum wheat.

Pyrasulfotole works in three different yet simultaneous ways to control broadleaf weeds.

Action One

Stops Growth & Initiates Demise

Pyrasulfotole (Group 27) is the first new mode of action to be developed in North America for broadleaf weed control in cereals in more than 20 years. It is absorbed through foliage and is translocated throughout the plant, resulting in marked systemic effects which quickly stops the plant’s growth and initiates the weed’s demise. This provides spring and durum wheat the opportunity to fully utilize available water and nutrientsto achieve full yield potential.

Action Two

Inhibits Enzymes & Starves Proteins

The ALS/AHAS inhibitor chemistry of thiencarbazone-methyl (Group 2) blocks normal function of an enzyme called acetolactate synthase (ALS) or actohydroxy acid synthase (AHAS) which is essential to amino acid (protein) synthesis. Without proteins, metabolic activity within the plant ceases and the plant starves to death.

Action Three

Cuts off the Protective Process

Bromoxynil (Group 6) works on contact, interfering with photosynthesis,disrupting plant growth which ultimately leads to the plant’s death.
