+PRODUCT INFORMATION
+Read all label directions before using.
+
+Rhythm® Herbicide is a herbicide that may be applied preplant, preemergence in Regions 1, 2, 
+3, and 4 and/or postemergence in all regions for control and suppression of broadleaf weeds, 
+grasses, and sedges in soybeans. Soybean plants are tolerant to Rhythm Herbicide when 
+applied according to labeled rates and uses. 
+Rhythm Herbicide is generally most effective and consistent when used postemergence, 
+working through contact action. Therefore, emerged weeds must be thoroughly covered with 
+spray. Some bronzing, crinkling, or spotting of soybean leaves may occur following 
+postemergence applications, but soybeans soon outgrow these effects and develop normally. 
+Optimum broad-spectrum weed control is achieved by postemergence applications of Rhythm 
+Herbicide to young actively growing broadleaf weeds that are not under stress from moisture, 
+temperature, and low soil fertility, mechanical or chemical injury. 
+Certain germinating broadleaf and grass weeds and sedges may be controlled or suppressed by 
+soil residual activity from either preplant, preemergence or postemergence applications if rainfall 
+occurs shortly after application. The extent and consistency of soil activity is dependent upon soil 
+type, ground cover at time of application, amount of rainfall and the rate of Rhythm Herbicide
+used. 
+APPLICATION DIRECTIONS
+TIMING:
+Best broad-spectrum postemergence control of susceptible broadleaf weeds is obtained when 
+Rhythm Herbicide is applied early to actively growing weeds. This usually occurs 14 to 28 days 
+after planting. Refer to the weed tables for specific recommendations on weed growth stages, 
+rates, and regions. 
+SPRAY ADDITIVES:
+Only spray additives cleared for use on growing crops under 40 CFR 180.1001 may be used in 
+spray mixture. 
+For best broad-spectrum postemergence control of susceptible broadleaf weeds in Regions 2, 3, 
+4 and 5 (see Regional Use Maps), Rhythm Herbicide should be used with 1.0-2.5% v/v liquid 
+nitrogen (28% or similar) or a minimum of 8.5 Ibs. ammonium sulfate per 100 gals. of spray 
+volume. 
+For Postemergence Applications Always Add One of the Following: except in tank mix with 
+products prohibiting spray additives - (See Tank Mix Directions for Use). 
+CROP OIL CONCENTRATE (COC):
+Use a nonphytotoxic COC or a once-refined vegetable oil concentrate (VOC, MSO) containing 
+15-20% approved emulsifier at 0.5-1 % (1-2 pts. per 25 gals.) of finished spray volume. COC can 
+improve weed control but may slightly reduce crop tolerance. 
+NONIONIC SURFACTANT (NIS):
+Use NIS containing at least 75% surface active agent at 0.25-0.5% (1/2-1 pt. per 25 gals.) of the 
+finished spray volume (Region 1 and East of Interstates 79 and 77 for Regions 2 and 3). 
+OTHER ADJUVANTS:
+Adjuvants other than COC or NIS may be used providing the product meets the following criteria: 
+1. Contains only EPA exempt ingredients. 
+2. Is nonphytotoxic to the target crop. 
+3. Is compatible in mixture. (May be established through a jar test.) 
+4. Is supported locally for use with Rhythm Herbicide on the target crop through proven field 
+trials and through university and extension recommendations. 
+NOTE: No adjuvants are needed for preplant or preemergence applications unless Rhythm 
+Herbicide is being used in a burndown. 
+Recommended Mixing Order:
+
+1. Half required amount of water, begin agitation. *
+2. Dry pesticide formulations. 
+3. Rhythm Herbicide.
+4. Liquid pesticide formulation. **
+5. Adjuvant (MSO, COC or NIS) and fertilizer. 
+*Compatibility agent, 1 gal./500 gals. of water or 0.2% v/v, may be added as needed. 
+**Tank mixing with glyphosate formulations containing more than 4 pounds glyphosate active 
+ingredient per gallon may result in precipitate forming. If precipitate forms in spray tank, add 
+ammonia (household) to the spray tank at a concentration of 2% of the total tank volume to 
+remove precipitate.
+GROUND APPLICATION:
+Use sufficient spray volume and pressure to ensure complete coverage of the target. A minimum 
+spray volume of 15 gals./A and 30-60 psi at the nozzle tip is recommended. On large weeds 
+and/or dense foliage, use 60 psi and a minimum of 20 gals./A to ensure coverage of weed 
+foliage. 
+Use only hollow cone or flat fan nozzles. The sprayer must be calibrated to provide the proper 
+volume and rate per acre. In addition, the boom and nozzle height must be adjusted to provide 
+complete coverage of the target. 
+DO NOT USE FLOOD TYPE OR OTHER SPRAY NOZZLES, WHICH DELIVER COARSE,
+LARGE-DROPLET SPRAYS. 
+DO NOT APPLY THIS PRODUCT THROUGH ANY TYPE OF IRRIGATION SYSTEM. 
+BAND APPLICATIONS:
+Thorough weed coverage is important for postemergence control. Best coverage is obtained with 
+a minimum of two nozzles, one directed to each side of the planted row. Application with a single 
+nozzle directed over the top of the row is not recommended for postemergence applications but 
+is suitable for preemergence applications. Cultivation of untreated areas may be needed 
+following band applications. When making postemergence band applications and cultivating in 
+the same operation, position nozzles in advance of the cultivation device. This will reduce dust in 
+the spray area. Dust can intercept spray, reducing weed coverage and resulting in less than 
+adequate weed control. Calculate the amount of herbicide and water volume needed for 
+postemergence band treatment by the following formulas: 
+Band width in inches X broadcast rate = Band herbicide rate
+Row width in inches per acre per acre
+Band width in inches X broadcast volume = Band water rate
+Row width in inches per acre per acre
+AERIAL APPLICATION:
+Use sufficient spray volume and pressure to ensure complete coverage of the target. A minimum 
+of 5 gals./A of spray mixture should be applied with a maximum of 40 PSI pressure. When 
+broadleaf weed foliage is dense, use a minimum of 10 gals./A to ensure coverage of weed 
+foliage. 
+CULTIVATION:
+Cultivation prior to application is not recommended. Cultivation may put weeds under stress, 
+reducing weed control. Timely cultivation 1-3 weeks after applying Rhythm Herbicide may assist 
+weed control. 
+PRECAUTIONS
+x Thoroughly clean the spray system with water and a commercial tank cleaner before and 
+after each use.
+
+x Tank mixes of Rhythm Herbicide with other pesticides, fertilizers or any other additives 
+except as specified on this label or other approved Cheminova supplemental labels may 
+result in tank mix incompatibility, unsatisfactory performance, and/or unsatisfactory crop 
+injury. 
+x Rhythm Herbicide requires a 1·hour rain·free period for best results when applied 
+postemergence. 
+x Apply postemergence to actively growing weeds. Avoid applying Rhythm Herbicide to 
+weeds or soybeans that are under stress from moisture, temperature, low soil fertility, or 
+mechanical or chemical injury, as reduced weed control and/or increased crop injury may 
+result. 
+x Avoid overlapping spray swaths, as injury may occur to rotational crops. 
+x To provide adequate coverage, it is recommended that ground speed not exceed 10 
+MPH during application. 
+RESTRICTIONS
+x A maximum of 1.6 pts. of Rhythm Herbicide (or a maximum of 0.375 Ibs. a.i./A of

+Suppression of Perennial Weeds: 
+Use of Rhythm Herbicide at postemergence rates of 0.75 pts./A will aid in suppressing the 
+above-ground portions of the weeds listed below until crop canopy can assist in suppression. 
+Perennial weeds continue to regrow from underground rootstocks even if above-ground foliage is 
+temporarily controlled or retarded. Even though Rhythm Herbicide and crop competition can 
+suppress perennial weeds for a growing season, the rootstocks will continue to live and 
+reestablishment will occur in subsequent years.

+RESTRICTIONS:
+x Refer to the Directions for Use for the maximum use rate for each Region specified 
+in the Regional Use Maps.
+x Application of Rhythm Herbicide in Regions 2, 3, 4 and 5 is limited to alternate years 
+only.
+TANK MIX AND SEQUENTIAL APPLICATIONS FOR SOYBEANS 
+Rhythm Herbicide can be used sequentially or in tank mix with one or more of the following 
+products: Assure II®, Basagran®, Butyrac®, Classic®, FirstRate®, Fusilade® OX, Fusion®, 
+Glyphosate (such as Glyfos“X-TRA, Roundup®, Touchdown®), Gramoxone® MAX, Harass®, 
+Harmony® GT, Harmony® GT XP, Ignite®, Poast®, Poast Plus®, Pursuit®, Raptor®, 
+Resource®, Scepter®, Select®, and Synchrony® STS®. 
+Under certain conditions, the mixture of Rhythm Herbicide with one or more of the above 
+mentioned broadleaf herbicides may cause a reduction in activity of any postemergence grass 
+herbicide in the mixture. 
+For sequential applications allow 2-3 days after the application of the grass herbicide before 
+applying Rhythm Herbicide or Rhythm Herbicide mixtures. Where Rhythm Herbicide or the 
+Rhythm Herbicide mixture is applied first, apply the grass herbicide when the grass weeds 
+begin to develop new leaves (generally around 7 days).
+

+AERIAL SPRAY DRIFT MANAGEMENT ADVISORY
+
+SPRAY DRIFT MANAGEMENT 
+AVOIDING SPRAY DRIFT AT THE APPLICATION SITE IS THE RESPONSIBILITY OF THE 
+APPLICATOR. The interaction of many equipment-and-weather-related factors determine the 
+potential for spray drift. The applicator is responsible for considering all these factors when 
+making decisions. 
+The following drift management requirements must be followed to avoid off-target movement 
+from aerial applications to agricultural field crops. These requirements do not apply to forestry 
+applications, public health uses, or to applications using dry formulations. 
+1. The distance of the outer-most nozzles on the boom must not exceed 3/4 the length of the 
+wingspan or rotor. 
+2. Nozzles must always point backward parallel with the air stream and never be pointed 
+downwards more than 45 degrees. 
+Where states have more stringent regulations, they should be observed. 
+The applicator should be familiar with and take into account the information covered in the 
+AERIAL DRIFT REDUCTION ADVISORY.
+AERIAL DRIFT REDUCTION ADVISORY 
+[This section is advisory in nature and does not supersede the mandatory label requirements.] 
+INFORMATION ON DROPLET SIZE 
+The most effective way to reduce drift potential is to apply large droplets. The best drift 
+management strategy is to apply the largest droplets that provide sufficient coverage and control. 
+Applying larger droplets reduces drift potential, but will not prevent drift if applications are made 
+improperly or under unfavorable environmental conditions (See Wind, Temperature, and
+Humidity, and Temperature Inversions). 
+CONTROLLING DROPLET SIZE 
+x Volume: Use high flow rate nozzles to apply the highest practical spray volume. Nozzles 
+with higher rated flows produce larger droplets. 
+x Pressure: Do not exceed the nozzle manufacturer's recommended pressures. For many 
+nozzle types lower pressure produces larger droplets. When higher flow rates are needed, 
+use higher flow rate nozzles instead of increasing pressure. 
+x Number of Nozzles: Use the minimum number of nozzles that provide uniform coverage. 
+x Nozzle Orientation: Orienting nozzles so that the spray is released parallel to the airstream 
+produces larger droplets than other orientations and is the recommended practice. 
+Significant deflection from horizontal will reduce droplet size and increase drift potential. 
+x Nozzle Type: Use a nozzle type that is designed for the intended application. With most 
+nozzle types, narrower spray angles produce larger droplets. Consider using low-drift 
+nozzles. Solid-stream nozzles oriented straight back produce the largest droplets and the 
+lower drift. 
+BOOM LENGTH 
+For some use patterns, reducing the effective boom length to less than 3/4 of the wingspan or 
+rotor length may further reduce drift without reducing swath width. 
+APPLICATION HEIGHT 
+Applications should not be made at a height greater than 10 ft. above the top of the target plants 
+unless a greater height is required for aircraft safety. Making applications at the lowest height 
+that is safe reduces exposure of droplets to evaporation and wind. 
+SWATH ADJUSTMENT 
+When applications are made with a crosswind, the swath will be displaced downwind. Therefore, 
+on the up and downwind edges of the field, the applicator should compensate for this 
+displacement by adjusting the path of the aircraft upwind. Swath adjustment distance should 
+increase with increasing drift potential (higher wind, smaller drops, etc.).
+
+WIND 
+Drift potential is lowest between wind speeds of 2-10 mph. However, many factors, including 
+droplet size and equipment type, determine drift potential at any given speed. Application should 
+be avoided below 2 mph due to variable wind direction and high inversion potential. NOTE: Local 
+terrain can influence wind patterns. Every applicator should be familiar with local wind patterns 
+and how they affect spray drift. 
+TEMPERATURE AND HUMIDITY 
+When making applications in low relative humidity, set up equipment to produce larger droplets
+to compensate for evaporation. Droplet evaporation is most severe when conditions are both hot 
+and dry. 
+TEMPERATURE INVERSIONS 
+Applications should not occur during a temperature inversion because drift potential is high. 
+Temperature inversions restrict vertical air mixing, which causes small suspended droplets to 
+remain in a concentrated cloud. This cloud can move in unpredictable directions due to the light 
+variable winds common during inversions. Temperature inversions are characterized by 
+increasing temperatures with altitude and are common on nights with limited cloud cover and 
+light to no wind. They begin to form as the sun sets and often continue into the morning. Their 
+presence can be indicated by ground fog; however, if fog is not present, inversions can also be 
+identified by the movement of smoke from a ground source or an aircraft smoke generator. 
+Smoke that layers and moves laterally in a concentrated cloud (under low wind conditions) 
+indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good 
+vertical air mixing. 
+SENSITIVE AREAS 
+The pesticide should be applied only when the potential for drift to adjacent sensitive areas (e.g. 
+residential areas, bodies of water, known habitat for threatened or endangered species, 
+nontarget crops) is minimal (e.g. when wind is blowing away from the sensitive areas).
