General Information


Touchdown Total is a nonselective foliar systemic herbicide for control of a broad spectrum of emerged annual and perennial grass and broadleaf weeds and unwanted woody brush and trees.

Touchdown Total is formulated as a liquid concentrate that contains 4.17 lb glyphosate acid equivalent per gallon, in the potassium salt form.


- Do not apply this product through any type of irrigation system.

- Do not apply this product by direct application (ground or air) to any body of water.

- DO NOT spray if conditions of thermal inversion exist or if wind direction and speed may cause spray to drift onto adjacent nontarget areas. Drift minimization is the responsibility of the applicator. Consult with local and State agricultural authorities for information regarding avoiding or minimizing spray drift.

- The MAXIMUM USE RATES indicated for Touchdown Total have been determined based upon the concentration of glyphosate acid (expressed as acid equivalents) contained in this product. The actual maximum application rates stated apply to the total amount of glyphosate acid equivalents applied to a given site in any year either from the application of this product alone or in combination with other glyphosate-containing products, applied either as mixtures with other products or separately. Application rates must be calculated to ensure that the use of this and other glyphosate-containing products do not exceed the maximum use rate as specified below unless otherwise specified in the specific use directions.

- In agricultural use sites and crop areas, do not exceed a total of 5.8 qt Touchdown Total/A, equivalent to 6 lb glyphosate acid equivalents per acre per year.

- In nonagricultural use areas, do not exceed a total of 7.6 qt Touchdown Total/A equivalent to 8 lb glyphosate acid equivalents per acre per year.

- Do not exceed 0.7 qt/A per application for applications made with aerial application equipment.

- For broadcast postemergence treatments, do not harvest or feed treated vegetation for 8 weeks following application, unless otherwise specified.

- Do not allow the herbicide solution to mist, drip, drift, or splash onto desirable vegetation since minute quantities of this product can cause severe damage or destruction to the crop, plants, or other areas on which treatment was not intended. When spraying, avoid combinations of pressure and nozzle type that will result in splatter or fine particles (mist) which are likely to drift. Avoid applying at excessive speed or pressure.

- Thoroughly clean the spray system with water and a commercial tank cleaner after each use.

- There are no rotational crop restrictions following application of this product.


- Touchdown Total requires actively growing green plant tissue to function. Application to drought-stressed weeds or weeds with little green foliage (e.g., mowed, cut, or hailed on weeds); weeds covered with dust; weeds damaged by insects or diseases may result in reduced weed control.

- Touchdown Total does not provide soil residual control of weeds. Weeds emerging after application will require retreatment.

- Heavy rainfall or irrigation shortly after application may require retreatment.

- Tillage or mowing within 3 days following application may reduce weed control.

- Touchdown Total is not volatile and cannot move as a vapor after application onto nontarget vegetation.

- Spray solutions of Touchdown Total should be mixed, stored, and applied using only plastic, plastic-lined steel, stainless steel, or fiberglass containers. Concentrate should not be stored in galvanized steel, carbon steel, aluminum, or unlined steel containers.

- Severe damage or destruction may be caused by contact of Touchdown Total to any vegetation (including leaves, green stems, exposed non–woody roots, or fruit) of crops, trees, and other desirable plants to which treatment is not intended, except as specified for glyphosate–tolerant crops.


Touchdown Total contains glyphosate which inhibits 5 enolpyruvylshikimate-3-phosphate synthase (EPSPS, Site of Action Group 9). Some naturally occurring weed populations have been identified as resistant to Group 9 herbicides.

Selection of resistant biotypes, through repeated use of these herbicides or lower than labeled use rates in the same field, may result in weed control failures. A resistant biotype may be present where poor performance cannot be attributed to adverse environmental conditions or improper application methods. If resistance is suspected, contact your local Syngenta representative and/or agricultural advisor for assistance.

General principles of herbicide resistant weed management:

- Employ integrated weed management practices. Use multiple herbicide sites-of-action with overlapping weed spectrums in rotation, sequences, or mixtures.

- Use the full labeled herbicide rate and proper application timing for the hardest to control weed species present in the field.

- Scout fields after herbicide application to ensure control has been achieved. Avoid allowing weeds to reproduce by seed or to proliferate vegetatively.

- Monitor site and clean equipment between sites.

- Start with a clean field and control weeds early by using a burndown treatment or tillage in combination with a preemergence residual herbicide as appropriate.

- Use cultural practices such as cultivation and crop rotation, where appropriate.

- Use good agronomic principles that enhance crop competitiveness.



Touchdown Total should be applied to actively growing emerged weeds. Annual weeds of 6 inches or less in height are typically the easiest to control. Generally, more effective control of perennial weeds is achieved at the flowering or seedhead stage. Refer to the WEEDS CONTROLLED, WOODY BRUSH AND TREES CONTROLLED sections, for specific application timing.

When annual weeds have been mowed or grazed, wait for 3-4 inches of new growth to appear prior to application.

When perennial weeds have been mowed or grazed, allow new growth to reach recommended stage prior to application.

Visible effects on annual weeds occur within 2-4 days after application; effects on perennial weeds may take 7 days or longer. Extremely cool or cloudy weather following treatment may slow activity.


Follow specified rates for Touchdown Total listed in the WEEDS CONTROLLED, WOODY BRUSH AND TREES CONTROLLED sections. Use the higher label rates when weeds are dense or large. Also, use higher application volumes and pressures when weed vegetation is dense.


- Preventing drift is the responsibility of the applicator. Applications should not be made in low level inversion conditions, when winds are gusty or under any other conditions which favor drift. Inversions are characterized by stable air and increasing temperatures with height above the ground. The applicator may detect the presence of an inversion by producing smoke and observing a smoke layer. Drift may cause damage to any vegetation contacted to which treatment is not intended.

- Compatibility with drift control additives may vary. Use the jar test to determine the compatibility of the combination.

Read and follow manufacturer’s directions for use. A reduction in weed control may occur when drift control agents are used.

- All equipment must be properly maintained and washed to remove product residues after use.



Make ground applications in 3 to 40 gallons of water per acre.

When foliage is dense, spray volume should be increased to ensure coverage of the target weeds. Flat-fan nozzles will result in the most effective application of Touchdown Total. Spray boom and nozzle heights must be adjusted to provide coverage of target weeds. Flood nozzles may result in reduced weed control due to inadequate coverage.

Do not make direct applications to any body of water.


Make aerial applications in 3 to 15 gallons of water per acre.

Spray should be released at the lowest height consistent with effective weed control and flight safety. Apply at a height no more than 10 ft above the canopy.

Use the largest droplet size consistent with good weed control. Formation of very small droplets may be minimized by appropriate nozzle selection, by orienting nozzles away from the air stream as much as possible, and by using the appropriate spray boom pressure. Solid stream or low shear nozzles may be utilized to reduce small droplet formation. These nozzles direct the fluid parallel to the existing airflow to reduce shear effects. Other techniques may include reducing the fan angle of flat fan nozzles if used, or reducing the deflector plate angle if deflector type nozzles are used. Ensure the spray is released at an appropriate distance below the airfoil.

For best results, each specific aerial application vehicle used should be quantifiably pattern tested for aerial application of Touchdown Total initially and every year thereafter. To minimize drift, it is suggested aerial application equipment produce the following minimum spray deposition characteristics:

Volume Median Diameter (VMD) › 400 microns

Volume Diameter (VD) {0.9} › 200 microns

Prolonged exposure of Touchdown Total to uncoated steel surfaces may result in corrosion and possible failure of the part. The maintenance of an organic coating (paint) which meets aerospace specification MIL-C-38413 may prevent corrosion. To prevent corrosion of exposed parts, thoroughly wash aircraft after each day of spraying to remove residues of Touchdown Total accumulated during spraying or from spills. Landing gears are most susceptible. For aerial application in California, refer to the Federal Supplemental Label for aerial application for specific instructions, restrictions, and requirements. For aerial application, consult with State or local authorities regarding any additional requirements for aerial treatments. Banvel tank mixtures may not be applied by air in California. Do not make direct applications to any body of water.


Use shielded/hooded sprayers to control weeds between rows while protecting the crop from the herbicide. Keep shields/hoods as close to the ground as possible and avoid ground speed in excess of 5 mph. Use appropriate nozzles, spacing, and pressure to achieve coverage without allowing spray to touch or drift onto the crop. Maintain equipment in good operating condition to prevent leakage or dripping onto the crop. Refer to state extension service recommendations and equipment manufacturers’ guidelines for more information on proper operation of shielded/hooded sprayers.


For annual weeds less than 6 inches, use a 0.4 to 0.7% v/v solution. For annual weeds over 6 inches, use a 0.7 to 1.1% v/v solution. Use a 0.7 to 1.5% v/v solution for most perennials (see Table 3 for specific rates and timing). When using motorized spot spray equipment (rider bar), use a 2.2% v/v solution. See Spot Spray Dilution Table below for rates of Touchdown Total/volume of finished spray solution. Spray the solution on actively growing weeds until uniformly wet but not to the point of runoff. Retreat 14-21 days later if regrowth occurs.


Touchdown Total may be applied using a wiper or “wick” applicator (e.g., rope, sponge, or porous plastic applicators) for selective control or suppression of annual and perennial weeds which become taller than the crop or desirable vegetation. Mix 3 qt of Touchdown Total in 2 gallons of water unless directed otherwise in the label (see Use Restrictions and Precautions for Berries, Fruits, Nuts, and Vines). Precautions should be taken to prevent contact with crops or desirable vegetation. Equipment should be operated at speeds of 5 mph or less. Use slower speeds where weeds are dense. For improved control, make two applications in opposite directions.

Injection Systems

Touchdown Total may be used in aerial or ground injection spray systems. It may be used as a liquid concentrate or diluted prior to injecting into the spray stream. Do not mix Touchdown Total with the undiluted concentrate of other products when using injection systems unless specifically directed.


For control of annual weeds with hand held equipment, apply a 20% solution of Touchdown Total at a flow rate of 2 fl oz per minute and a walking speed of 1.5 mph (1 qt/A). For perennial weeds, use a 20 to 30% solution of Touchdown Total at a flow rate of 2 fl oz per minute and a walking speed of 0.75 mph (2 to 3 qt/A). For vehicle mounted equipment, apply in 3 to 15 gallons of water per acre. Refer to the WEEDS CONTROLLED, WOODY BRUSH AND TREES CONTROLLED sections, for application rates and timing.

Precautions should be taken to prevent contact with crops or desirable vegetation.

Refer in the label for tank mix information.
