What are the different groups of herbicides?

Some Common Herbicide Groups:

  • Group 1 – ACCase inhibitors – (Fops and Dims) – These products are typically grass.
  • Group 2 – ALS/AHAS inhibitors – These products block the normal function of this.
  • Group 3 – Microtubule assembly inhibitors – These chemicals inhibit cell division in.

    • What is a Group 4 herbicide?

    Group 4: Plant growth regulators. Also known as synthetic auxins, this group includes hormone-based herbicides and is used to keep broadleaf weeds out during the cultivation of corn, wheat, and sorghum.

    What are Group A herbicides?

    Group A herbicides are a key tool for post-emergent control of volunteer cereals and grass weeds in canola. Group A herbicides work by inhibiting cell production of acetyl co-enzyme A carboxylase (ACCase) in susceptible weeds.

    What does Group 2 herbicide mean?

    Group 2 includes. four herbicide families, the imidazolinones, sulfonylureas, sulfonamides and. triazolopyrimadines. Some of these herbicides control grassy weeds, others broadleaves. and some both.

    What is the most commonly used herbicide?

    Glyphosate
    Glyphosate—known by many trade names, including Roundup—has been the most widely used herbicide in the United States since 2001. Crop producers can spray entire fields planted with genetically engineered, glyphosate-tolerant (GT) seed varieties, killing the weeds but not the crops.

    How do Group A herbicides work?

    Group A herbicides inhibit the acetyl-CoA carboxylase (ACCase) enzyme. One of the factors resulting from inhibition of this enzyme is reduction in the production of fatty acids required for construction of cell membranes needed for new cell production.

    What is Group B herbicide?

    Group B herbicides are presently the only in-crop herbicides that provide effective control of these grass weeds and this poses a severe risk of Group B resistance for growers with cereal dominant rotations. Avoid applying more than two Group B herbicide treatments in any four year period on the same paddock.
