Fast-acting Control of Tough Aquatic Weeds.



Nufarm Diquat SPC 2L herbicide provides non-selective control of aquatic weeds on contact. It spreads through the water for broad-spectrum control and is completely inactivated on contact with soil.


KEY PERFORMANCE BENEFITS
  • Works quickly — no waiting for aquatic weed control
  • Broad-spectrum activity successfully controls key aquatic weeds
  • Non-systemic, contact activity controls only the weeds it contacts
  • Easy-to-use liquid formulation makes application trouble-free

APPLICATION RECOMMENDATIONS
Use this product for general weed control in commercial greenhouses (ex., beneath benches), for field grown and container stock, and in other similar areas. Make applications of this product preplant or postplant pre-emergence in field grown ornamental nursery plantings, or post-emergence as a directed spray. For ornamental seed crops (NOT registered for use in the State of California), apply this product pre-emergence. Do not allow sprays to contact desirable foliage or injury will occur. Do not use on food or feed crops.

(22 ml) of this product plus the manufacturer’s specified rate of a nonionic surfactant (contains 75% or greater nonionic surfactant) per 1 gallon of water.

Broadcast Application Rates: 1 to 2 pts. of this product in a minimum of 15 gallons of water per acre plus a nonionic surfactant (contains 75% or greater nonionic surfactant) at the manufacturer’s specified rate per 100 gals of spray mixture.

RESTRICTIONS AND PRECAUTIONS
Obtain all necessary approval and/or permits before application if required. Consult the responsible state agencies (i.e., Fish and Game Agencies, State Water Conservation authorities, or Department of Natural Resources).

Apply this product by those applicators certified for aquatic pest control authorized by the State or local government, Federal or State public agencies such as Water Management District personnel and municipal officials, and by Corps of Engineers.

For water bodies containing dense weeds, apply this product to only 1/3 to 1/2 of the water body area at one time. If a repeat application is required, wait for 14 days. Using this product in this manner will prevent loss of oxygen in the water body which occurs when dead weeds begin to decompose which often leads to suffocation of fish.

Do not apply this product in areas where commercial processing of fish which produces fish protein concentrate or fish meal is practiced. Prior to application, coordinate application with and obtain approval from local and/or State authorities.

Use water treated with this product only after the specified number of days have passed after application (refer to the table if product label for these water use restrictions). Alternatively, use the water at a different time after application only if an approved assay (ex. PAM II Spectrometric Method) shows that no more than the designated maximum contaminant level goal (MCLG) of 0.02 mg/L (ppm) of diquat dibromide (calculated as the cation) is present in the water.

If posting is required by your State or Tribe, consult the agency responsible for pesticide regulations for specific details.
