Clipper SC Makes Headlines

Posted by | Clipper News | No Comments

Tough. Fast. Gone.

Clipper® SC delivers fast and selective control of tough invasive and nuisance plants such as cabomba, watermeal, Eurasian watermilfoil, water lettuce, duckweed, giant salvinia and more. Plus, Clipper SC dissipates quickly from the water column and does not accumulate in sediment. With 4 lb of flumioxazin per gallon, Clipper SC offers easier handling and mixing.

 

 
CLIPPER DELIVERS UNBEATABLE AQUATIC WEED CONTROL
  • Convenient liquid formulation improving ease of application, transport, and handling – 1 liquid fl oz Clipper SC = 1 dry oz Clipper WDG
  • Fast and selective control of tough invasive and nuisance plants
  • Dissipates quickly from the water column and does not accumulate in sediment, giving it a favorable environmental profile
  • Easy mixing, handling, and measuring
  • Less packaging
  • Improved efficacy with less pH sensitivity
 
USE SUMMARY
Clipper® SC is a contact herbicide that quickly degrades in water. Good coverage and contact time is essential. Make applications with sufficient volume of water according to the label. When making applications to floating or emergent weeds, apply at 6 to 12 fl oz per acre and mix with an adjuvant approved for aquatic sites. For subsurface applications, apply Clipper SC at 200 to 400 ppb in the water column. Please see label for information on the effects of high pH on plant response and efficacy.

 

CLIPPER® SC BLOOMS AND MIXES EASILY AND STAYS IN SUSPENSION
Unlike WDG formulations, liquid Clipper SC blooms quickly and mixes easily. With only slight agitation, Clipper SC mixes evenly and completely. Plus, it stays in suspension longer – even after two hours without agitation Clipper SC shows no signs of settling.

 

PRECAUTIONS AND RESTRICTIONS
No restrictions for swimming, drinking, or fishing.

DO NOT apply to intertidal or estuarine areas.

In areas with dense weed vegetation only treat 1/2 the water body at one time and wait 10-14 days before treating the remaining area. DO NOT re-treat the same section of water within 28 days of application.

Treated water may not be used for irrigation purposes on food crops until at least five days after application.

Treated water may be used for irrigation purposes on turf and landscape ornamentals as outlined in the Irrigation Restrictions Following Application table below.

DO NOT use in water utilized for crawfish farming.

Clipper Now Registered for use in California!

Valent Professional Products and Nufarm announced that Clipper Aquatic Herbicide has been registered by the California Department of Pesticide Regulation for use by golf course superintendents, lawn care operators and aquatic resource managers in California.

A fast-acting contact herbicide, Clipper is the only PPO inhibitor with proven activity on both floating and submersed plants, providing valuable flexibility for applicators. Clipper selectively controls a number of invasive and nuisance aquatic plants, including submersed plants such as hydrilla, Eurasian watermilfoil, curlyleaf pondweed and cabomba, as well as floating plants such as duckweed, watermeal, giant salvinia and water lettuce.Green weeds and algae growing in a pond.

With a new chemistry and a new mode of action for California applicators, Clipper plays an important role in herbicide resistance management programs. Additionally, Clipper offers reduced personal protective equipment (PPE) requirements compared to many other products, a convenient package size and a non-corrosive, dry, flowable formulation for easy mixing, transport and application.

“The aquatics industry in California has lacked options for control of tough plants such as duckweed and watermeal as well as invasive species such as water lettuce,” said Dr. Mike Riffle, manager of development and technical services for Nufarm. “Clipper provides these markets with a new mode of action for control of floating and submerged weeds, an effective new tool for invasive species control and versatile application methods for ease of use.”

Registered for use via foliar and/or surface spray, submersed injection or aerial application, Clipper works swiftly and then dissipates quickly from the water column and does not accumulate in sediment, an important attribute for California applicators.

“California has a lot of the same problems we have in other parts of the country, but, due to a continued lack of rainfall, they are a lot more reliant on their ponds for irrigation,” said Dr. Joe Chamberlin, regional field development manager for Valent Professional Products. “Duckweed, watermeal and filamentous algae clog irrigation systems if left unchecked, making it even more critical to control these plants so that irrigation systems can keep working.”

As part of an agreement announced by Valent U.S.A. Corporation and Nufarm in February, Clipper is now available exclusively through Nufarm.

Clipper vs. Parrotfeather (Clipper wins)

Posted by | Clipper News | No Comments

The aquatic weed Parrotfeather is a rooted weed that generally grown in shallow subsurface areas throughout the United States and many other countries. The plant gets its name from due to its appearance which is usually similar to bunches of leaves that become emergent as the plant matures. The emergent portion of the plant swirls and groups to form a dense mat, thus the name Parrotfeather.Parrotfeather in canal area

The plants are not entirely detrimental to the pond provided growth is not excessive. Letting parrotfeather flourish unattended for years can result in virtually all areas of the pond being completely covered. As the old growth dies down, it begins to decompose which provides nutirents for the aquatic life within the water. Exorbitant amounts of decomposition can lead to oxygen depletion and can have a negative impact on the ponds entire ecosystem.

As Parrotfeather left untamed can become a true nuisance weed, growth control is always preferred since the weed is invasive and there are many alternate, less all consuming, options to add to your aquatic foray.Parrotfeather in stream

Clipper herbicide containing flumioxazin is an excellent choice when dealing with excess Parotfeather infestation. Clipper is a fast acting contact control product that will eradicate all target weeds when applied per labeling. It is best to apply Clipper early in the day and quickly after tank mixing the spray solution. Light blocking aquatic dye’s such as Aquashade can help control growth prior to a Clipper application. Follow all directions on container labels to assure maximum blockage.

Mass Approves Clipper 2014

MASS SAY’S “CLIPPER’S A GO” for 2014

MDAR/MassDEP 1 June 2013 -reposted here 2014
CLIPPER® HERBICIDE PRODUCT EVALUATION AND
RECOMMENDATION
(June 2013)

MDAR/MassDEP 2 June 2013
This document is a review of the aquatic herbicide Clipper® (EPA. Reg. No. 59639-161; Valent
Biosciences Corp.). It contains product-specific aspects related to use characterization, inert
formulation ingredients and adjuvants, and toxicity and effects of these ingredients to human
health and non-target organisms. This document complements the MDAR/MassDEP review of
the active ingredient flumioxazin (MDAR/MassDEP 2013).
1. Product Formulation
The product label indicates that the Clipper Herbicide is formulated as water dispersible granules
containing 51% flumioxazin by mass (Valent Corp., 2012). The MSDS document indicates that
the formulation also contains kaolin clay as a carrier at approximately 16% by mass. The identity
of the other ingredients (also referred to as inerts) in Clipper Herbicide is considered proprietary;
therefore, the manufacturer does not identify the other ingredients on the general or supplemental
product labels or material safety data sheets (MSDS).
Proprietary information on the other formulation ingredients was obtained through a request for a
Confidential Statement of Formula. The proprietary ingredients were evaluated as part of this
review, but cannot be disclosed here for reasons of confidentiality.
The product label indicates that treatment of emergent vegetation requires the addition of spray
adjuvants to the tank mix. As directed on the label, only adjuvants labeled for aquatic use should
be utilized. Specific recommendations for adjuvants include those that contain non-ionic
surfactants.
2 Use Characterization
2.1. Use Sites
The product label for the flumioxazin-formulated Clipper Herbicide specifies that this product
may be applied for the control of vegetation in aquatic sites. Clipper Herbicide provides control
of various submerged, emergent, and floating aquatic plants. The product may be applied directly
to the water where there is limited or no outflow, including wetlands, lakes, fresh water ponds
and reservoirs (Valent Corp., 2012).
2.2. Application Methods
Clipper Herbicide is applied as a water-based solution having a pH of 5 to 7. If treating floating
or emerged weeds the addition of an adjuvant to the tank mix is needed. The product may be
broadcast applied to the water surface or injected below the water surface. The label suggests
that early morning applications may enhance weed control. The product may be applied by
backpack or handgun sprayer, airboat, helicopter, airplane or other application equipment that is
MDAR/MassDEP 3 June 2013
capable of thorough coverage of target plant foliage. Subsurface application may be done using
weighted trailing hoses to ensure the release of the herbicide under the surface and throughout
the biomass of aquatic vegetation. In situations where aquatic vegetation is dense, the label
suggests that up to half of the water body be treated at a time to avoid a rapid decrease in
dissolved oxygen caused by vegetation breakdown. It also notes that the remaining area of the
water body can be treated 10 to 14 days later.

Clipper™ Aquatic Herbicide Registered for Immediate Application for Use on Invasive Weeds

Provides Aquatic Managers with Much-Needed New Tool for Selective Plant Management

January 4, 2014 (original posting 1+ years ago)

Clipper™ aquatic herbicide and algaecide has recently been registered by the Environmental Protection Agency (EPA) for use to combat a variety of aquatic plant infestations. Clipper™ equips pond and lake service outfits with rapid, highly effective knockdown product for use on nuisance selective weeds and plants. With a fast, effective and much-needed new tool for selective aquatic plant control and resistance management.

Unlike some systemic products (fluridone) which can take months to remediate infestation, Clipper™  is  and is the only PPO inhibitor with proven activity on both floating and submersed plants. Clipper™ provides valuable flexibility for applicators and selectively controls a range of invasive and nuisance weeds and algae. Clipper™ controls:

  1. hydrilla
  2. Eurasian watermilfoil
  3. curlyleaf pondweed
  4. cabomba
  5. duckweed
  6. watermeal and more!

This exciting new technology affords pond and lake owners the ability to take back their pond without risking random shot-in-the dark type application. Clipper plays an important role in herbicide resistance management programs. And, Clipper works rapidly followed by a fast dissipates in the water column. It does not accumulate in sediment.

Clipper™ offers reduced personal protective equipment (PPE) requirements compared to many other products, a convenient package size and a non-corrosive, dry, flowable formulation for easy mixing, transport and application.

“We have helped tens of thousands of pond owners eradicate nuisance weeds with many of those treatments including fluridone based products. Fluridone is systemic and must remain in the water column for quite a while to be effective, and can take time to show desired results.” said Don Tephart, NTB Aquatics, Inc.,  “With Clipper™, the results are night and day and flow isn’t really a major issue, especially compared to the former. It does the job right and is easy to apply. We like what Valent has done here and we plan on using it as part of our complete arsenal against invasive weeds/algae”
