label booklet, applications must be made at least 30 days prior to planting. Applications must be made prior 
to the emergence of the crop to avoid crop injury. 
Shielded Sprayers 
USE INSTRUCTIONS: Apply 1.2 to 3.6 pounds of this product in 10 to 20 gallons of water per acre to 
control weeds between grass seed rows. Uniform planting in straight rows aid in shielded sprayer 
applications. Best results are obtained when the grass seed crop is small enougb to easily pass by the 
protective shields. For additional instructions, see "Shielded Applicators" in the "APPLICATION 
EQUIPMENT AND TECHNIQUES" section of this product's label booklet. 
PRECAUTIONS, RESTRICTIONS: Contact of this product in any manner to any vegetation to \\'I11ch 
treatment is not intended may cause damage. Such damage shall be the sole responsibility of the applicator. 
Wiper Applications Over-the-Top 
USE INSTRUCTIONS: Applicators should be adjusted so tbat the wiper contact point is at least 2 mehes 
above the desirable vegetation. Weeds should be a minimum of6 inches above the desirable vegetation. 
Bener results may be obtained when more of the weed is exposed to the herbicide solution. "VI,T eeds not 
contacted by the herbicide solution will not be affected. This may occur in dense clwnps, severe 
infestations, or when height of weeds varies so that not all weeds are contacted. In these instances, repeat 
treatments may be necessary. For additional instructions, see "Wiper Applicators" in the" APPLICATION 
EQUIPMENT AND TECHNIQUES" section of this product's label booklet. 
PRECAUTIONS, RESTRICTIONS: Contact of the herbicide solution with desirable vegetation may result 
in damage or destruction. 
Spot treatments 
USE INSTRUCTIONS: Use a 1.0- to 2.0 -percent solution. 
PRECAUTIONS, RESTRICTIONS: Apply this product prior to heading of grasses grown for seed. The 
crop receiving the spray in the treated area will be killed. Take care to avoid drift or spray outside the target 
area for the same reason. Hand-held equipment may be used to control sod remnants or other unwanted 
vegetation after sod is harvested. 
Creating Rows in Annual Ryegrass 
USE INSTRUCTIONS: Use 0.6 to 1.2 pounds of this product per acre. Use tbe higher rate when the 
ryegrass is greater than 6 inches tall. Best resuhs are obtained when applications are made before the 
ryegrass reaches 6 inches in height. 
PRECAUTIONS, RESTRICTIONS: Set nozzle heigbts to allow the establishment of the desired row 
spacing while preventing spray droplets, spray fines, or drift to contact the ryegrass plants not treated. Use

planting. 
PRECAUTIONS, RESTRlCTIONS: If application rates total 3.6 pounds per acre or less, no waltmg pcnod 
between treatment and feeding or livestock grazing is required. If the rate is greater than 3.6 pound'- per 
acre, remove domestic livestock before application and wait 8 weeks after application before grazing or 
harvesting. Crops listed for treatment in the label booklet may be planted into the treated area at any tlllle: 
for other crops, wait 30 days between application and planting. 
Spot Treatment, Wiper Applications Over-the- Top 
USE INSTRUCTIONS: This product may be applied as a spot treatment or with wiper applIcators m 
pastures. Applications may be made in the same area at 30-day intervals. 
PRECAUTIONS, RESTRlCTIONS: For spot tre~tments or wiper applIcation methods USIng rates of .'.1, 
pounds per acre or less, the entire field or any portion of it may be treated. When spot treatments or wiper 
application are made using rates above 3.6 pounds per acre, no more than 10 percent of the total pasture 
may be treated at anyone time. To achieve maximum perfonnance, remove domestic livestock before 
application and wait 7 days after application before grazing livestock or harvesting. 
Post emergent Weed Control (Broadcast Treatments) 
USE INSTRUCTIONS: This product may be used to suppress competitive growth and seed production of 
annual weeds and undesirable vegetation in pastures. For selective applications with broadcast spray 
equipment, apply 7 to 1 () ounces of this product per acre in early spring before desirable perennial grasses 
break dormancy and initiate green growth. Late fall applications can be made after desirable perennial 
grasses have reached donnancy. 
PRECAUTIONS, RESTRlCTIONS: Some stunting of perennial grasses will occur if broadcast applications 
are made when plants are not dormant. No waiting period is required between application and grazing or 
harvesting for feed. Use of higher application rates will cause stand reductions. Do not apply more than 
3.6 pounds per acre per year onto pasture grasses except for renovation uses (see instructions above). If 
replanting is needed due to severe stand reduction, applications must be made at least 30 days prior to 
planting any crop not listed for treatment in this product's label booklet,

Preventing viable seed production is key to the successful control and invasion of annual grassy weeds in 
rangelands. Follow-up applications in sequential years should eliminate most of the viable seeds. 
Grazing of treated areas should be delayed to encourage growth of desirable perennials. Allowing desirable 
perennials to flower and reseed in the treated area will encourage successful transition. 
USE INSTRUCTIONS: Apply 7 to 10 ounces of this product per acre to control or suppress many weeds, 
including downy brome, cheatgrass, cereal rye and jointed goatgrass in rangelands. Apply when most 
brome plants aTe in early flower and before the plants, including seedbeads, tnrn color. Allowing for 
secondary weed flushes to occur in the spring following rain events further depletes the seed reserve and 
encourages perennial grass conversion on weedy sites. Fall applications are possible, and recommended, 
where spring moisture is usually limited and fall germination allows for good weed growth. 
For medusahead, apply 10 ounces of this product per acre at the 3-leaf stage. Delaying applications beyond 
this stage will result in reduced or unacceptable control. Controlled burning may be useful in eliminating the 
thatch layer produced by slow decaying culms prior to application. Allow new growth to occur before 
spraying after a burn. Repeat applications in subsequent years may be necessary to eliminate the seedbaok 
before reestablishing desirable perennial grasses in medusahead-dominated rangelands. 
PRECAUTIONS, RESTRICTIONS: Slight discoloration of the desirable grasses may occur, but they will 
regreen and regrow under moist soil conditions as effects of this product wear off. Do not use ammonium 
sulfate when spraying rangeland grasses with this product. No waiting period between treatment and 
feeding oflivestock grazing is required. Do not apply more than 3.6 pounds per acre per year. 
Read the "Limit of Warranty and Liability" in the label booklet for Roundup UltraDry Herbicide 
before using. These terms apply to this supplemental labeling and if these terms are not acceptable, 
return the product unopened at once.
