First Full Year with Procellacor Herbicide in the Books

In mid summer of 2019, the Washington Department of Ecology added Procellacor herbicide to our state’s permit and to date the results have been stunning.  We have delivered close to 100 percent control in all cases where we have applied it.

Procellacor is a product that was registered by the US EPA as a reduced risk herbicide.  It can be applied to lakes, rivers and reservoirs without any restriction on the use of treated water for Potable Supply, Swimming, Fishing or irrigating turf grass (there are short irrigation restrictions for some ornamental species).  It also has the fastest plant accumulation factor or uptake of any aquatic herbicide we have in the tool box.

In our region the primary invasive aquatic weeds we fight is Eurasian Milfoil or hybrid strains of that species.  Procellacor is becoming our go to technology for combating this plant.  Procellacor is selective for milfoils, it is systemic and will control the entire plant and it provides long term control.

In conjunction with SePRO Corporation Procellacor can come with a three year warranty and payment program as well so you have the opportunity to do more work in year one and stretch payments over three seasons.

Procellacor is available through Pro Certified Applicators such as our team.  For more information on this product and the Pro Certification Process, you may visit https://sepro.com/aquatics/procellacor-applicators

 

McDowell Lake Eurasian Milfoil Control Successful

McDowell Lake is located in the Little Pend Oreille National Wildlife Refuge just east of Coville, Washington.  This lake was revered by fly fishers throughout the northwest as one of our premier fishing waters.  In the mid 2000’s, the invasive weed Eurasian Milfoil was introduced to the systems.  This noxious weed rapidly filled the water column lake wide and choked off access to the fishery.  As this pristine water was walk in walk out, fishers with tubes could not move around the lake through the thick growth.

The US Fish and Wildlife Service turned to Aquatechnex to help solve this problem.  Aquatechnex has a long history of providing programs that can eradicate this invasive species from a water body.  We designed and delivered a program that utilized timed treatments of Sonar Aquatic Herbicide in the new Precision Release Pellet technology in 2006. The key to this success is being able to maintain low doses of Sonar in contact with the target vegetation for an extended period of time.  The Precision Release Pellet is designed to help accomplish that goal.

In the summer of 2007 and 2008, Aquatechnex divers have surveyed the lake and determined that the system remains milfoil free.  This lake is added to the list of lake systems we have successfully eradicated Eurasian Milfoil from using our technology.  In addition, as is generally the case, native aquatic plants are thriving in the nitch that used to be occupied by the noxious invader.

Renovate OTF takes to the field

For years one of the only options we had for selective control of Eurasian Milfoil in high water exchange areas was 2,4-D.  This chemistry served us well.  Milfoil is a member of the broadleaf plant family and most native aquatic plants we look to protect are in the grass family.  Using this systemic herbicide allowed us to selectively target the milfoil and allowed the natives to recover into the space that used to be occupied by the milfoil. 

About four years ago, SePRO Corporation brought a new chemistry with similar charactoristics to the marketplace,  Renovate was registered by EPA about 2002.  We have used this product extensively and found that it provides much longer term control than 2,4-D applications while protecting the native plant communities.  We use this technology to restore native plant communities in infested water bodies.  The liquid formulation of Renovate however could be costly in deeper water applications.

To address this concern, SePRO has developed and released a new form of this product, Renovate OTF (stands for On Target Flake).  This light granular material sinks through the water column and sticks to the target plants.  This allows us to treat from the lake bottom up, not the other way around.  This is a major step in making this product more cost effective and we will be starting to deploy it in the field in the next few weeks.  For more information see:

Eradication of Invasive Aquatic Weeds, Can it Happen?

This is often a topic our clients ask us about when they undertake a control program focusing on Eurasian Milfoil or one of the other invasive plant species that plague their lakes. At last week’s Western Aquatic Plant Management Society Meeting (www.wapms.org) Kathy Hamel of the Washington Department of Ecology presented an interesting paper on this subject. She highlighted a number of successful eradication efforts that have been conducted in Washington State. Our firm was responsible for the implementation of most of those programs. Read more
