PERENNIAL WEEDS - BLUEGRASS KENTUCKY, BROMEGRASS SMOOTH, ORCHARDGRASS
DO NOT ALLOW CONTACT WITH EXPOSED NON-WOODY ROOTS, FRUIT, FOLIAGE OR GREEN STEMS OF DESIRABLE TREES AND PLANTS AS SEVERE PLANT INJURY OR DESTRUCTION COULD RESULT.
Use only in accordance with instructions on the label. Read the entire label before use, including the LIMITED WARRANTY, TERMS OF SALE, AND LIMITATIONS OF LIABILITY section. If the terms in this section are not acceptable, immediately return unopened product. Glyphosate T&O IS AN END-USE PRODUCT AND IS NOT REGISTERED FOR REFORMULATION.
DO NOT APPLY Glyphosate T&O BY AIR, EXCEPT UNDER SPECIFIC CONDITIONS LISTED WITHIN THE LABEL.
Glyphosate T&O is a water soluble liquid that readily mixes with water for application as a foliar spray to control or destroy most herbaceous plants. This product can be applied by using most standard industrial or field-type sprayers after it is diluted and thoroughly mixed with water.
Glyphosate T&O works by moving through the plant from where it contacts the foliage to and into the root system. Within 2 to 4 days, visible effects on most annual weeds are apparent; however, effects may not be visible on most perennial weeds for 7 days or more. Effectiveness and visual effects of this product may be slower if very cool or cloudy weather follows treatment. A gradual wilting and yellowing of the plant will be visible, which then advances to total browning of all aboveground growth and deterioration of underground plant parts.
Unless stated otherwise within the label, application should be delayed until vegetation has emerged and has reached the specific stages described for control of vegetation under the WEEDS CONTROLLED sections of the label. Unemerged plants that arise from unattached underground rhizomes or root stocks of perennials are not affected by Glyphosate T&O, and will keep growing. Because of this, treatment should be made at late growth stages (approaching maturity) for best control of the majority of perennial weeds.
Always apply the higher rate of this product per acre within recommended ranges when weed growth is heavy or dense, or, when weeds are growing in a noncultivated, nondisturbed area.
Reduced weed control may result if weeds are treated when drought stress, insect damage, or disease is present. Additionally, if weeds are heavily covered with dust, reduced weed control will result.
Effectiveness may be reduced if applications are made to annual or perennial weeds that have been grazed, mowed or otherwise cut, unless they have been permitted to regrow to their recommended stages for treatment.
If rainfall or irrigation occurs within 6 hours of application, reduced effectiveness may result. Heavy irrigation or rainfall within 2 hours of application may wash off the chemical from foliage. In this case, a repeat treatment may be required.
Glyphosate T&O does not provide residual weed control. Use a label approved herbicide program if subsequent residual weed control is desired. Users must read and carefully observe all cautionary statements and all other information on labels of all herbicides used.
NOTE: Buyer and users are responsible for all losses or damage resulting from the use and/or handling of mixtures of Glyphosate T&O with herbicides or other materials that are not specifically recommended on this product label. Reduced performance may result if users mix Glyphosate T&O with other herbicides or other products not recommended on the label.
Best results are obtained with uniform and complete spray coverage.
However, DO NOT spray weed foliage to the extent of runoff.
DOMESTIC ANIMALS: Glyphosate T&O is considered to be relatively nontoxic to dogs and other domestic animals. Note, however, that ingestion of this product, or of large amounts of vegetation that has been freshly sprayed with this product, may cause temporary gastrointestinal irritation, such as diarrhea, colic, vomiting, etc. If these symptoms are observed, the animal should be given plenty of fluids in order to prevent dehydration. A veterinarian should be contacted in the event symptoms persist for more than 24 hours.
NOTE: Using this product in a manner not consistent with the product label may result in personal injury, injury to animals or crops, or in other unintended consequences.
APPLY THESE SPRAY SOLUTIONS IN PROPERLY MAINTAINED AND CALIBRATED EQUIPMENT WITH THE CAPACITY TO DELIVER THE DESIRED VOLUMES. DO NOT APPLY WHEN WIND OR OTHER CONDITIONS FAVOR DRIFT. DIRECT HAND-GUN APPLICATIONS PROPERLY TO AVOID SPRAYING DESIRABLE PLANTS. NOTE: POOR RESULTS MAY OCCUR IF WATER CONTAINING SOIL IS USED, SUCH AS WATER FROM PONDS AND UNLINED DITCHES.
For mixing, additives, and application instructions for Industrial, Turf, and Ornamental uses, see the section titled NON-CROP USES.
APPLICATION EQUIPMENT AND TECHNIQUES
DO NOT apply this product through any type of irrigation system.
The following application equipment may be used when applying this product.
By Air: Helicopter and Fixed Wing.
By Broadcast Spray:
Controlled Droplet Applicator (CDA)—Boom mounted or hand held applicators that produce spray with a narrow range of droplet sizes.
Hand-Held and High-Volume Spray Equipment—Pump up pressure sprayers, handguns, mistblowers*, handwands, knapsack and backpack sprayers, lances and other hand held and motorized spray equipment used to direct the spray directly onto the weed foliage.
Ground Broadcast Spray—Boom or boomless systems, pull-type sprayer, pick-up sprayers, floaters, spray coupes and other ground broadcast equipment.
Injection Systems—Aerial or ground injection sprayers.
* This product is not registered in Arizona or California for application with mistblowers.
Selective Equipment—Wiper applicators, shielded sprayers, and recirculating sprayers.
Review the Selective Equipment section of the discussion below for rates of application and specific instructions.
For control of those perennial or annual weeds listed on the label, using broadcast equipment. Unless otherwise specified on the label, use the recommended rates of Glyphosate T&O in 3 to 40 gallons of water per acre. Review the WEEDS CONTROLLED sections of the label for specific rate information. As weed density increases, spray volume should increase (within the recommended range) to ensure adequate coverage. Avoid spraying a fine mist by carefully selecting the proper nozzle. Use flat fan nozzles for best results when using ground application equipment. Apply with an even distribution of spray droplets.
This product 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 this product with the undiluted concentrate of other products when using injection systems unless specifically recommended.
CONTROLLED DROPLET APPLICATION (CDA)
When applying Glyphosate T&O by vehicle mounted CDA equipment, the rate of this product per acre must not be less than the amount recommended on the label when applied by conventional broadcast equipment.
For vehicle mounted CDA equipment, use 3 to 15 gallons of water per acre.
To control labeled annual weeds with hand held CDA equipment, apply a 20 percent solution of Glyphosate T&O at a flow rate of 2 fluid ounces per minute and a walking speed of 2.2 feet/second (equivalent to 1 quart per acre). To control labeled perennial weeds, apply a 20 to 40 percent solution of Glyphosate T&O at a flow rate of 2 fluid ounces per minute with a walking speed of 1.1 feet/second (equivalent to 2 to 4 quarts per acre).
The spray pattern of CDA equipment is not easily visible. Exercise extreme care to avoid spray or drift contacting any foliage or green tissue of desirable vegetation. Severe damage or destruction may result.
HAND-HELD and HIGH-VOLUME EQUIPMENT
Use coarse sprays only.
Clean water should be used when mixing this product; then apply to the foliage of vegetation to be controlled. For those applications that are to be made on a spray-to-wet basis, ensure uniform and complete spray coverage. DO NOT spray product to the point of runoff.
To control annual weeds that are listed on the label, spray a 0.5 percent solution of Glyphosate T&O plus nonionic surfactant to weeds that are smaller than 6 inches in height or runner length. This product should be applied before seedhead formation in grass, or before bud formation in broadleaf weeds. DO NOT till or mow for at least three days after application, unless otherwise specified.
Unless otherwise specified, for annual weeds over 6 inches tall, or if additional surfactant is not to be used, use a 1 percent solution. On harder to control perennials (such as dock, field bindweed, hemp dogbane, bermudagrass, milkweed and Canada thistle), best results are obtained by using a 2 percent solution.
If using application methods that result in less than total coverage, a 5 percent solution should be used for perennial and annual weeds, and use a 5 to 10 percent solution for trees and woody brush.
To prepare the desired volume of spray solution, mix the proper amount of Glyphosate T&O in water in accordance with the table below.
When using knapsack sprayers, mix the recommended amount of Glyphosate T&O with water in a larger container. Then fill sprayer with the mixed solution.
Glyphosate T&O may be applied through a recirculating spray system, a hooded sprayer, a sponge bar, a wiper applicator, or a shielded applicator after dilution and thorough mixing with water. It may be applied to the weeds listed on the label that are growing in any non-crop site specified on the label, but only when specifically recommended in cropping systems.
A recirculating spray system works by directing the spray solution onto those weeds growing above desirable vegetation. Any spray solution not intercepted by the weeds is then collected and returned to the sprayer for reuse.
A shielded applicator works by directing the herbicide solution onto weeds, while at the same time shielding desirable vegetation from the herbicide.
A wiper applicator works by rubbing weeds with an absorbent material that contains the herbicide solution.
IMPORTANT: DO NOT LET THIS PRODUCT OR SPRAY MIXTURE COME INTO CONTACT WITH DESIRABLE VEGETATION.
If this product comes into contact with desirable vegetation, severe damage or destruction may result. Adjust applicators that are used above desired vegetation to ensure the lowest spray stream or wiper contact point is a minimum of 2 inches above desirable vegetation.
Discoloration, stunting or plant destruction may result if mist, foam, droplets, or splatter of the herbicide solution settles on desirable vegetation.
Applications made above the crops should be made when the weeds are a minimum of 6 inches above the desirable vegetation. Better results may be obtained when more of the weed is exposed to the herbicide solution. Weeds not contacted by the herbicide solution will not be affected. This may occur in dense clumps, severe infestations or when the height of the weeds varies so that not all weeds are contacted. In these instances, repeat treatment may be necessary.
When this product is applied in accordance with label instructions for shielded applicators, Glyphosate T&O will control weeds listed in the WEEDS CONTROLLED sections of the label.
Nozzles that provide uniform coverage within the area treated should be utilized. To protect desirable vegetation, make sure shields on shielded sprayers are adjusted properly. EXERCISE EXTREME CAUTION TO AVOID HERBICIDE CONTACT WITH DESIRABLE VEGETATION. See the WEEDS CONTROLLED sections of the label for specific rates of application and instructions for control of perennial and annual weeds.
WIPER APPLICATORS AND SPONGE BARS
Wiper applicators are meant to physically wipe an appropriate amount of Glyphosate T&O onto weeds.
Wiper applicator equipment must be designed, operated, and maintained to ensure the herbicide solution does not contact desirable vegetation. This equipment should be operated at ground speeds of 5 mph or less. Improved performance may be attained by reducing speed in areas having heavy weed infestations; this ensures adequate wiper saturation. Better results are possible if 2 applications are made in opposite directions.
Avoid dripping or leaking herbicide onto desirable vegetation. To ensure adequate contact with weed surfaces, adjust the height of the applicator.
Wiping surfaces should be kept clean. If applying on sloping ground, this product may migrate, thereby causing dripping on the lower end and wick drying on the upper end of the wiper applicator.
If weeds are wet, DO NOT use wiper equipment.
When mixing the herbicide solution, mix only enough solution to be used during a 1 day period; reduced effectiveness may result from using leftover solution amounts. Wiper parts should be cleaned immediately by thoroughly flushing with water when application is completed.
DO NOT add surfactant to the herbicide solution.
For Rope or Sponge Wick Applicators – Mix 1 gallon of this product in 2 gallons of water to prepare a 33 percent solution. Apply this solution to weeds listed in this WIPER APPLICATORS AND SPONGE BARS section.
For Industrial, Turf, and Ornamental uses, solutions ranging from 33 to 75 percent of Glyphosate T&O in water may be used.
For Porous-Plastic Applicators: Solutions varying from 33 to 100 percent of Glyphosate T&O in water may be used.
For Panel Applicators and Pressure-feed Systems: Solutions ranging from 33 to 100 percent of this product in water may be used.
Glyphosate T&O CONTROLS the weeds listed when applied using WIPER APPLICATORS AND SPONGE BARS as recommended under this section.

AERIAL APPLICATIONS IN ARKANSAS ONLY
AVOID CONTACT OF HERBICIDE WITH FOLIAGE, GREEN STEMS, EXPOSED NON-WOODY ROOTS OR FRUIT OF CROPS, DESIRABLE PLANTS AND TREES, BECAUSE SEVERE INJURY OR DESTRUCTION MAY RESULT.
See the GENERAL INFORMATION and MIXING sections of the label booklet for essential product performance information.
AVOID DRIFT. DO NOT APPLY INTO STILL AIR WHERE THERE IS A TEMPERTURE INVERSION LAYER LOW ENOUGH FOR FINE SPRAY PARTICLES TO BECOME SUSPENDED AND MOVE OUTSIDE THE TARGET AREA WHEN THE INVERSION LAYER MOVES. DO NOT APPLY WHEN WINDS ARE GUSTY OR UNDER ANY OTHER CONDITION THAT FAVORS DRIFT. DRIFT IS LIKELY TO CAUSE DAMAGE TO ANY VEGETATION CONTACTED. TO PREVENT INJURY TO ADJACENT DESIRABLE VEGETATION, APPROPRIATE BUFFER ZONES MUST BE MAINTAINED.
Use the recommended rate of this product in 3 to 15 gallons of water per acre.
Use sufficient carrier volume and appropriate equipment set-up to form droplets large enough to avoid drift potential. Coarse droplets in the 300 to 500 (VMD) micron range are recommended.
Applications should typically be made with the nozzle release point at 8 to 15 feet above the top of the target plants unless a greater height is required for aircraft safety.
The distance of the outermost nozzles on the boom must not exceed 75% of the length of the wingspan or rotor. In many cases, reducing this distance to 65% of the length of the wingspan or rotor will improve drift control without affecting the swath width.
Nozzles must always discharge backward parallel with the air stream and never discharge downwards more than 45 degrees on fixed wing aircraft or forward of the prevailing air flow on rotary winged aircraft.
Avoid the use of nozzles with wide angle discharge.
DO NOT apply this product when winds are in excess of 10 miles per hour.
DO NOT apply when there is a low-level inversion where fine spray particles could be suspended in still air and move outside the target area when the inversion layer moves. These conditions may occur when wind speeds are less than 2 mph.
Use the following guidelines when applications are made near crops or other desirable vegetation:
1. DO NOT apply within 100 feet of any desirable vegetation or crops.
2. If wind up to 5 miles per hour is blowing toward desirable vegetation or crops, DO NOT apply within 500 feet upwind of the desirable vegetation or crops.
3. Winds blowing from 5 to 10 miles per hour toward desirable vegetation or crops will likely require buffer zones in excess of 500 feet.
Refer in the label for tank mix information.
For controlling or destroying most perennial weeds, apply Glyphosate T&O as follows.
For application instructions and perennial weeds controlled for Industrial, Turf, and Ornamental uses, see the section titled NON-CROP USES. NOTE: In the event weeds have been tilled or mowed, DO NOT treat plants until they have resumed active growth AND have reached the recommended stages.
It may be necessary to repeat treatments on those weeds that regenerate from underground parts or from seed. These repeat treatments must be applied before crops emerge.
Improved performance on perennial weeds may be attained with the addition of 1 to 2 percent dry ammonium sulfate by weight, or 8.5 to 17 pounds per 100 gallons of water. The increased effectiveness may be most apparent if environmental stress is present. Review the sections of the label titled MIXING ADDITIVES and APPLICATION INSTRUCTIONS.
Glyphosate T&O will CONTROL the PERENNIAL WEEDS listed if applied as directed under the conditions described.
For specific application instructions and labeled uses, review the DIRECTIONS FOR USE and MIXING, ADDITIVES, and APPLICATION INSTRUCTIONS sections of the label.
Bluegrass, Kentucky; Bromegrass, smooth; Orchardgrass: Use 2 quarts of Glyphosate T&O in 10 to 40 gallons of water per acre. Apply when grasses are actively growing and when most plants have developed to the boot-to-early seedhead stage. For partial control in pasture or hay crop renovation, use 1 to 1.5 quarts of Glyphosate T&O plus 0.5 to 1 percent nonionic surfactant by total spray volume in 3 to 10 gallons of water per acre. Apply to actively growing weeds when most are 4 to 12 inches high. Wait a minimum of 7 days after treatment before tillage.
Orchardgrass (sods going to no-till corn): Use 1 to 1.5 quarts of Glyphosate T&O per acre plus 0.5 to 1 percent nonionic surfactant by total spray volume in 3 to 10 gallons of water per acre. Orchardgrass should be at least 12 inches high for spring treatment, and 6 inches high for fall treatment. Wait a minimum of 3 days before planting. For best results, a sequential application of atrazine is necessary. When using tank mixes, review the tank-mix herbicides’ individual product labels for specific crops, application rates, geographical restrictions, and precautionary statements.
