DIRECTIONS FOR USE It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application. For any requirements specific to your State or Tribe, consult the State or Tribal agency responsible for pesticide regulation. AGRICULTURAL USE REQUIREMENTS Use this product only in accordance with its labeling and with the Worker Protection Standard, 40 CFR part 170. This standard contains requirements for the protection of workers on farms, forests, nurseries, and greenhouses, and handlers of agricultural pesticides. It contains requirements for training, decontamination, notification, and emergency assistance. It also contains specific instructions and exceptions pertaining to the statements on this label about personal protective equipment and restricted-entry intervals. The requirements in this box only apply to uses of this product that are covered by the Worker Protection Standard. Do not enter or allow worker entry into treated areas during the restricted-entry interval (REI) of 4 hours unless wearing appropriate PPE. EXCEPTION: If the product is soil-incorporated, the Worker Protection Standard, under certain circumstances, allows workers to enter the treated area if there will be no contact with anything that has been treated. PPE required for early entry to treated areas that is permitted under the Worker Protection Standard and that involves contact with anything that has been treated such as plants, soil, or water, is: x coveralls over long-sleeved shirt and long pants, x chemical-resistant gloves, and x shoes plus socks. CHEMIGATION INFORMATION Apply this product only through furrow irrigation systems. Do not apply this product through any other type of irrigation system. Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from non-uniform distribution of treated water. If you have questions about calibration, you shoul d contact State Extension Service specialists, equipment manufacturers or other experts. Do not connect an irrigation system (including greenhouse systems) used for pesticide application to a public water system unless the pesticide label prescribed safety devices for public water systems are in place. A person knowledgeable of the chemigation system and responsible for its operation, or under supervision of the responsible person, shall shut the system down and make necessary adjustments should the need arise. Maintain agitation in the supply tank while adding the required amount of ASCEND WSG, and throughout the application. ASCEND WSG should be added to the supply tank at the end of water application (prior to last complete cycle in moving systems). The correct amount of ASCEND WSG to add is calculated as the rate in ounces per acre x the number of acres covered by the contents of the supply tank. 2

(For example, if the supply tank covers ten acres and the rate on the label for that crop is 0.2 ounces per acre, add 10 x 0.2 = 2.0 ounces to the supply tank at the beginning of the last full cycle). CHEMIGATION SYSTEMS CONNECTED TO PUBLIC WATER SYSTEMS Public water system means a system for the provision to the public of piped water for human consumption if such system has at least 15 service connections or regularly serves an average of at least 25 individuals daily at least 60 days out of the year. Chemigation systems connected to public water systems must contain a functional, reduced- pressure zone, backflow preventer (RPZ) or the functional equivalent in the water supply line upstream from the point of pesticide introduction. As an option to the RPZ, the water from the public water system should be discharged into a reservoir tank prior to pesticide introduction. There shall be a complete physical break (air gap) between the outlet end of the fill pipe and the top or overflow rim of the reservoir tank of at least twice the inside diameter of the fill pipe. The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the flow of fluid back toward the injection pump. The pesticide injection pipeline must contain a functional, normally closed, solenoid-operated valve located on the intake side of the injection pump and connected to the system interlock to prevent fluid from being withdrawn from the supply tank when the irrigation system is either automatically or manually shut down. The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when the pump motor stops, or in cases where there is no water pump, when the water pressure decreases to the point where pesticide distribution is adversely affected. Systems must use a metering pump, such as a positive displacement injection pump (e.g. diaphragm pump) effectively designed and constructed of materials that are compatible with the pesticides and capable of being fitted with a system interlock. Do not apply when wind speed favors drift beyond the area intended for treatment. The pesticide supply tank should be agitated throughout the application of ASCEND WSG. ASCEND WSG should be applied at the end of the water application. ASCEND WSG should be applied at the end of the irrigation period in a sufficient amount of water to allow proper coverage of plant or crop but not to exceed 18 fluid ounces of ASCEND WSG per acre per application. IN-FURROW CHEMIGATION

1. Systems using a gravity flow pesticide dispensing system must meter the pesticide into the water at the head of the field and downstream of a hydraulic discontinuity such as a drop structure or weir box to decrease potential for water source contamination from backflow if water flow stops.
2. Systems utilizing a pressurized water and pesticide injection system must meet the following requirements: a. The system must contain a functional check valve, vacuum relief valve, and low pressure drain appropriately located on the irrigation pipeline to prevent water source contamination from backflow. b. The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the flow of fluid back toward the injection pump. 3

c. The pesticide injection pipeline must also c ontain a functional, normally closed, solenoid- operated valve located on the intake side of the injection pump and connected to the system interlock to prevent fluid from being withdrawn from the supply tank when the irrigation system is either automatically or manually shut down. d. The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when the water pump motor stops. e. The irrigation line or water pump must include a functional pressure switch which will stop the water pump motor when the water pressure decreases to the point where pesticide distribution is adversely affected. f. Systems must use a metering pump, such as a positive displacement injection pump (e.g., diaphragm pump) effectively designed and constructed of materials that are compatible with pesticides and capable of being fitted with a system interlock. Maintain agitation in the supply tank while adding the required amount of ASCEND WSG, and throughout the application. ASCEND WSG should be added to the supply tank at the end of water application (prior to last complete cycle in moving systems). The correct amount of ASCEND WSG to add is calculated as the rate in ounces per acre x the number of acres covered by the contents of the supply tank. (For example, if the supply tank covers ten acres and the rate on the label for that crop is 0.2 ounces per acre, add 10 x 0.2 = 2.0 ounces to the supply tank at the beginning of the last full cycle). APPLICATION INFORMATION IMPORTANT: Read the entire "Directions for Use" and the "Notice" before using this product. If terms are not acceptable, return the unopened product container at once. ASCEND WSG must be solubilized in water prior to use. DO NOT mix or attempt to solubilize directly into fertilizer. Apply ASCEND WSG by ground or air. If applied by air, use 3 to 5 gallons of water per acre. If applied by ground on vegetable or field crops, use 5 to 25 gallons of water per acre. For tree crops, apply 50 to 200 gallons of water per acre. For turfgrass, apply ASCEND WSG by ground using 0.5 to 2.5 gallons of water per 1,000 square feet. Test results have shown that this product can stimulate higher yields through a larger root mass, earlier fruiting and increased fruit retention. ASCEND WSG is a tool to increase plant efficiency.

NOTE: If seed has been treated with ASCEND WSG, do not apply ASCEND WSG as an in-furrow, band, side dress or mark out application. FOLIAR SPRAY PROGRAM FOR RICE Apply ASCEND WSG at 0.4 ounces per acre as a foliar spray to the plant during either one of the following stages of development. Primary Recommendations - 3 to 7 Leaf Stage: This application must be made after the rice seedling has 3 fully emerged leaves and the 4th leaf is beginning to emerge, but before the seedling has completed development of 7 leaves or 3 tillers. This period for application generally begins about 3-6 weeks after seeding and ends 5-9 weeks after seeding. The duration of this period 9

depends on the variety and the growing conditions. This application may be made in conjunction with corresponding herbicide applications. Alternate Recommendation - Two Millimeter (mm) Panicle Growth Stage: If the primary application is missed, ASCEND WSG can be applied to stimulate cell differentiation in the developing panicle. This application must be made when no more than 10% of the main culms are at the 2 mm panicle growth stage. The 2 mm panicle growth stage occurs immediately after internode elongation or joint movement has begun. ASCEND WSG must be applied as soon as internode elongation is detected so the 2 mm panicle growth stage is not missed. It is better to apply slightly early than to apply late. IMPORTANT: Timing of the application at 2 mm growth stage is critical. Check the entire field for stage of plant development. Large fields may require split applications on upper and lower ends of the field to ensure proper timing throughout the field. TURFGRASS On all turfgrass, regardless of use, use no more than 0.04 ounces per 1,000 square feet per month. WARM SEASON TURF (Bermuda, Bermuda hybrids, Zoysia, Centipede, St. Augustine, etc.): For lower traffic areas and where ASCEND WSG is used as a maintenance program, begin applications early in the growing season. Apply at the rate of 0.01 to 0.02 ounces per 1,000 square ft. Maintenance application should be made on a two to three week schedule throughout the growing season. Applications can be made with foliarly-applied urea for added benefits. COOL SEASON TURF (Tall Fescue, Rye, Bentgrass, Bluegrass, etc.): Apply 0.02 ounces per 1,000 square feet in fall, or when stand is established. Repeat application in late winter when grasses begin to grow actively. APPLICATION WITH FOLIARLY-APPLIED UREA: Maximum benefit and color can be achieved when ASCEND WSG applications are made with foliarly-applied urea solutions. To prepare urea solution, dissolve 46% urea into spray solution at the rate of 1.0 lb. per 5,000 square feet to be sprayed and apply with specified rate of ASCEND WSG. SPECIFIC RATES OF APPLICATION TEES AND GREENS: Apply 0.01 to 0.02 ounces per 1,000 square feet on a 2 week schedule throughout the growing season. Begin in early spring after grasses have begun to grow. Sunbelt and transition zones should continue spray program throughout playing season. Courses north of the transition zone should continue applications through September. FAIRWAYS: Begin applications in early spring as soon as grasses have begun to actively grow. Apply 0.01 ounce per 1,000 square feet and repeat on a monthly schedule as long as grass is growing. PRE-TOURNAMENT QUICK GREEN-UP: Apply at the rate of 0.01 to 0.02 ounces per 1,000 square feet in conjunction with urea solution 4 to 5 days prior to playing time. Make application with a minimum spray volume of 0.5 gallon of water per 1,000 square feet. POST-STRESS RECOVERY: Apply 0.01 ounces ASCEND WSG per 1,000 square feet immediately after stressful event. Repeat application 7 to 14 days after initial application to increase root growth and overcome stress. SPRING DORMANCY BREAK: Apply 0.01 ounce per 1,000 square feet in spring as soon as new growth (opening) is visible. Raking of thatch prior to making this application is most desirable. Application at this time generates rapid growth and often reduces incidence of “spring die back” on certain species of grass. 10

FALL APPLICATION FOR WINTER HARDINESS: Make 2 applications 7-10 days apart in late summer or early fall just prior to the cessation of normal active growth. Apply 0.01 to 0.02 ounces per 1,000 square feet. Make application with a spray volume of 0.5 gallon of water per 1,000 square feet. Applications at this time will greatly increase root mass and depth of roots. Winter kill problems are often greatly reduced. COMMERCIAL TURF, CEMETERIES, ATHLETIC FIELDS, GOLF COURSES, AND OTHER FINE TURF AREAS: Applications of 0.01 to 0.02 ounces per 1,000 square feet made at any point during the growing season will produce desirable results. Make applications during the very early growth stages and continue on a regular monthly schedule throughout the growing season. Healthier and more beautiful turf can be realized in high traffic areas such as golf greens and tees by making regular applications every two weeks. SOD FARMS Apply 0.6 to 1.1 ounces per acre on a monthly basis during the growing season. Two weeks prior to cutting sod, make an application of 0.6 to 1.1 ounces per acre. SPECIFIC RATES OF APPLICATION After sod is cut, a reestablishment program is necessary. Start this program as soon as there is any greening over 30% of the area. Spray with 0.6 to 1.1 ounces per acre of ASCEND WSG. Repeat in 2 weeks and thereafter once per month throughout the growing season. Make a final application of 0.6 to 1.1 ounces per acre 2 weeks before dormancy. Start the monthly program again as soon as some green-up has started in the spring. When species started from seed have reached 1 inch in height, the monthly treatment may be started and followed in the same way as non-seeded varieties. SPECIAL NOTE FOR ALL DIRECT SEEDED GRASSES Acting through its unique combination of plant growth regulators, ASCEND WSG may be used as a seed dressing that aids in enhancing germination and early season root and top growth. For every 100 pounds of seed prepare slurry of 0.3 to 0.6 ounces ASCEND WSG with one fluid ounce of water. Thoroughly mix slurry with the seed to insure uniform coverage. Improper coverage will minimize product performance. NOTE: When applying to more than 100 pounds of seed up to 2 ounces of ASCEND WSG can be slurried with one fluid ounce of water. SEED TREATMENT SPECIAL NOTE FOR ALL DIRECT SEEDED CROPS Acting through its unique combination of plant growth regulators, ASCEND WSG may be used as a seed dressing that aids in enhancing germination and early season root and top growth.
