General Instructions

Shark® Aquatic Herbicide is a liquid formulation which is emulsifiable in water. It is designed to be mixed with water and applied to aquatic areas for control of floating and emerged weeds. Weed control is more effective on immature, actively growing weeds than on mature, less actively growing weeds. This product is a contact herbicide with little or no residual activity at recommended use rates.

 

This product is rapidly absorbed through the foliage of plants. Within a few hours following application, the foliage of susceptible weeds may show signs of desiccation, and in subsequent weeks, necrosis and death of the plant.

 

Extremes in environmental conditions (e.g. temperature, light and pH), may affect the activity of this product. Under warm conditions, herbicide symptoms may be accelerated.

 

Evidence suggests that dense infestations of Cabomba may lead to lower levels of control. Furthermore, this product is a contact herbicide and usually requires re-treatment as some plants may escape herbicide contact. It is recommended that a repeat application be applied to achieve very high levels of control.

 

However, DO NOT apply subsequent applications to the waterbody within 3 months.

 

Use of dirty or muddy water when preparing spray mixtures to apply this product may result in reduced herbicidal activity.

 

To Calculation the of rate of Shark® Aquatic Herbicide to use

 

To calculate the amount of Shark® Aquatic Herbicide to use, the following calculation can be used:

  • Measure the length and breadth of the Cabomba infested area to be treated in meters.
  • Measure the maximum depth of the Cabomba infested water in meters (take several measurements and use an average).
  • Multiply the length by the breadth by the average maximum depth. This gives a volume in cubic meters.
  • Multiple this figure by 0.004 (0.004 is a conversion factor that takes into account the slope of the sides of the waterbody as well as water volume).
  • Multiply this figure by 830 mL

The result is the amount of Shark® Aquatic Herbicide (in mL) to be applied to the area where Cabomba is growing.

 

Mixing

 

Add half the required volume of water in spray tank and start agitation. Add the measured amount of Shark Aquatic Herbicide next. Add balance of water to tank. Mix in 50 L of water as a minimum. Maintain good agitation at all times until spraying is completed.

 

Resistance Weeds Warning

 

Shark Aquatic Herbicide is a member of the Aryl triazolinone group of herbicides. Its mode of action is through a process of membrane disruption, which is initiated by the inhibition of the enzyme protoporphyrinogen oxidase. This inhibition interferes with the chlorophyll biosynthetic pathway. For weed resistance management Shark is a Group G herbicide.

 

Some naturally occurring weed biotypes resistant to Shark and other herbicides that inhibit the enzyme protoporphyrinogen oxidase may exist through normal genetic variability in any weed population. The resistant individuals can eventually dominate the population if the herbicides are used repeatedly. These resistant weeds will not be controlled by Shark or other herbicides that inhibit the enzyme protoporphyrinogen oxidase. Since the occurrence of resistant weeds is difficult to detect prior to use, FMC Australasia Pty Ltd accepts no liability for any losses that may result from the failure of Shark Aquatic Herbicide or other herbicides that inhibit the enzyme protoporphyrinogen oxidase.

 

Safety Directions

 

Store in the closed, original container in a cool, well-ventilated area. Do not store for prolonged periods in direct sunlight.

 

Triple rinse containers before disposal. Add rinsings to spray tank. If not recycling, break, crush or puncture and deliver empty packaging to an approved waste management facility.

 

DO NOT burn empty containers or product.

 

Refillable containers: Empty contents fully into application equipment. Close all valves and return to point of supply for re-fill or storage.

 

Spillage - In case of spillage, confine spilled product with material such as sand or clay.

 

Dispose of waste as indicated below or according to the Australian Standard 2507 - Storage and Handling of Pesticides. DO NOT allow spilled product to enter sewers, drains, creeks or any other waterways. Keep out animals and unprotected persons.

 

Vacuum, shovel or pump waste into an approved drum. To decontaminate spill area, tools and equipment, wash with a suitable solution (ie organic solvent, detergent, bleach or caustic) and add the solution to the drums of wastes already collected. Label for contents.

 

Dispose of drummed wastes, including decontamination solution, in accordance with the requirements of Local or State Waste Management Authorities
