Herbicides Mode of Action:

• Growth Regulators:  disrupt hormone balance and protein synthesis.
• Amino Acid Synthesis Inhibitors:  prevents the production of certain essential amino acids by inhibiting a key plant enzyme.
• Lipid Inhibitors:  prevent the formation of fatty acids in plants essential for the production lipids (vital for the cell membrane structure and new plant growth).
• Seedling Growth Inhibitors:  these herbicides interfere with new plant growth, thereby reducing the ability of seedlings to develop normally in the soil.  If a plant has not taken up the herbicide prior to emergence from the soil, it will not likely be affected.
• Photosynthesis Inhibitors:  shut down the food-producing process by inhibiting photosynthesis.
• Cell Membrane Disruptors:  these herbicides are activated by sunlight at which time they form oxygen compounds that destroy plant tissue by rupturing plant cell membranes.
