TIMING AND METHOD OF APPLICATION
Early Post-Seeding Applications to Submerged Weeds:
鈥? DSA applications may be applied by helicopter or ground at the early post-seeding timing to water-
seeded rice.
鈥? Apply Shark H2O herbicide at 8 ounces of product per acre (0.2 pounds active ingredient/acre).
鈥? Rice must be at the 2 to 4 leaf stage, well rooted and vigorously growing at the time of application.
Earlier applications may cause unacceptable crop response.
鈥? The flood water must be 3 to 6 inches deep. Keep the flood water static for at least five days after
application of Shark H2O herbicide.
鈥? Apply Shark H2O Herbicide to labeled weeds at the 2-leaf stage or less.
鈥? All applications must be with properly calibrated equipment and all equipment must be approved
by FMC prior to applying Shark H2O Herbicide.
鈥? Applications should be made by helicopter or ground equipment fitted with drop tubes and spray
orifices that produce a solid stream of liquid.
鈥? Total volume of diluted spray solution shall not be less than three gallons per acre.
鈥? Delivery pressure must not exceed 20 pounds per square inch.
鈥? Flying speed shall not exceed 60 miles per hour.
鈥? Recommended release height above paddy surface: helicopter 2 to 4 feet; ground 6 to 12
inches. Do not exceed a release height of 8 feet by helicopter or one foot by ground.
鈥? Apply in passes not exceeding 50 feet to insure even distribution throughout the flood water.
鈥? Applicators must attend FMC Stewardship Training, follow the loading, application and
equipment calibration instructions provided by FMC Corporation.
