GENERAL INFORMATION
Product Description: This product is a postemergent, systemic herbicide. It is generally non-selective and gives broad spectrum control of many annual weeds, perennial weeds, woody brush and trees.

Time to Symptoms: This product moves through the plant from the point of foliage contact to and into the root system. Visible effects on most allDual weeds occur within 2 to 4 days, but on most perennial weeds may not occur for 7 days or more. Extremely cool or Cloudy weather following treatment may slow activity of this product and delay development of visual symptoms. Visible effects are a gradual wilting and yellowing of the plant which advances to complete browning of above-ground growth and deterioration of underground plant parts.

Stage or Condition of Weeds: Weeds must be emerged at the time of application to be controlled by this product. Weeds germinating from seed after application will not be·controlled. Unemerged plants arising from unattached underground rhizomes or root stocks of perennials will not be affected by the herbicide and will continue to grow. Weeds under poor growing conditions such as drought stress, disease or insect damage, may absorb less herbicide resulting in reduced weed control. Reduced results may also occur when treating weeds heavily covered with dust.
Reduced control may result when applications are made to annual or perennial weeds that have been mowed, grazed, or cut, and have not been allowed to regrow to the recommended stage for treatment. Refer to the annual, perennial, woody brush and trees rate tables for recommendations for specific weeds.

Rainfastness: Heavy rainfall soon after application may wash this product off of the foliage and a repeat application may be required for adequate control.

Spray Coverage: For best results, spray coverage should be unifonn and complete. However, spraying herbicide solution to the point of runoff is wasteful and should be avoided.

Biological Degradation: Degradation of this product is primarily a biological process carried out by soil microbes.

Tank Mixing: This product does not provide residual weed control. For subsequent residual weed control, follow a label-approved herbicide program. Read and carefully observe the cautionary statements and all other infonnation appearing on the labels of all herbicides used. Use according to the most restrictive label directions for each product in the mixture, including retreatment intervals, and preharvest intervals. Carefully follow the maximum annual treatment rate for 2,4-D when mixing with other 2,4-D containing products. When this label recommends a tank mixture with a generic active ingredient such as atrazine or dicamba, the user must ensure that the mixture product's label allows the specific application site.
Buyer and all users are responsible for all loss or damage in connection with the use or handling of mixtures of this product with herbicides or other materials that are not expressly recommended in this labeling.
Mixing this product with herbicides or other materials not recommended on this label may result in reduced perfonnance.

Annual Maximum Use Rate: Except as otherwise specified in a crop section of this label, the combined total of all treatments must not 8 quarts of this product per acre per year. [Optional Statement: This maximum rate is equivalent to 0.64 pounds of2,4-D acid equivalents per acre per year and 6 pounds of glyphosate acid equivalents per acre per year.]
For noncrop uses, the combined total of all treatments must not exceed 10.6 quarts of this product per acre per year. [Optional Statement: This maximum rate is equivalent to 0.85 pounds of2,4-D acid equivalents per acre per year and 8 pounds of glyphosate acid equivalents per acre per year.]
The maximum use rates stated throughout this product's labeling apply to this product combined with the use of all other herbicides containing 2,4-D, glyphosate or sulfosate as the active ingredient, whether applied as mixtures or separately. Calculate the application rates and ensure that the total use of this and other products do not exceed stated maximum use rates.
