Audit 1:1 is a Group 2 herbicide containing Thifensulfuron-methyl (25.0%) and Tribenuron-methyl (25.0%) as active ingredients. It is a water dispersible granule designed for use on wheat, barley, oats, triticale, and fallow. This product is used to control various broadleaf weeds. It can be applied as a pre-plant or pre-emergence burndown treatment, a post-emergence application during crop growth, or a post-harvest treatment to control stubble. Application rates vary depending on the target crop and timing, ranging from 0.4 to 1.0 ounce per acre. When used in tank mixes, specific instructions must be followed to avoid crop injury. Handling requires wearing long-sleeved shirts, long pants, chemical-resistant gloves, and shoe covers. Avoid contact with eyes, skin, or clothing. If contact occurs, rinse eyes with water for 15-20 minutes and wash skin with soap and water. Always follow sprayer calibration and wind speed precautions to prevent off-target drift.
