New Tools for Homeowners Associations in North Idaho Combating Eurasian Milfoil

May 11, 2012

With the advent of a permit program to treat invasive aquatic weeds in Idaho, Aquatechnex is positioned to provide a number of technologies to help homeowners groups maintain their waterfronts.  Our company has worked on North Idaho Lakes since 2000, we were the successful respondent to Bonner County’s $1.8 million control program in 2006 and 2009 through this past year.  The programs we designed and implemented in 2006 on Lake Pend Oreille have resulted in areas that are still milfoil free today, six years later.  As the ISDA program has limited funding and many not be able to help in all cases, we can provide programs to those interested in moving forward where no state funding is available.

Sonar Aquatic Herbicide has played an very important role in Lake Pend Oreille and elsewhere in the Pacific Northwest.  This product can be used without placing any restrictions on the use of treated water and provides long term control.  Many areas treated in 2006 on Lake Pend Oreille remain milfoil free as of last summer.  Other areas there experienced 3-4 years of control before milfoil moved back in from other parts of the lake.  This technology is low cost per acre and delivers excellent control where it is applicable.

In 2010 we performed a number of water exchange studies on the Pend Oreille River comparing liquid triclopyr herbicide efficacy to that of controlled release granular products such as Renovate OTF.  In all cases, the OTF formulations resulted in better exposure and control of the plants, the herbicide is released over time and the plants get a higher dose.  Under the new permit, EPA requires that the control be delivered with the lowest possible amount of herbicide.  Renovate OTF and Renovate LZR granular triclopyr formulations have demonstrated that they can deliver better control using less herbicide than liquid triclopyr applications in high water exchange environments.  This technology can work in areas with higher water exchange.

Our team has been working with Home Owners Associations since 1984 in the Pacific Northwest.  If you’d like a representative to meet with you and your group please contact us at 208-338-8490 or tmcnabb@aquatechnex.com

Phoslock NSF Certification

November 23, 2011

Aquatechnex has been working with Phoslock, a phosphorus locking technology for lakes, for the past two years.  We have found this product to be highly effective in reducing the amount of phosphorus present in lake systems.  As this nutrient drives algae blooms, this technology limits the carrying capacity of a lake system to produce algae blooms.

This past week, Phoslock received is NSF/ANSI Standard 60 certification.  This clears the product for direct application to potable water reservoir systems.  For more information go to www.aquatechnex.wordpress.com

 


Eurasian Milfoil in Hope Marinas Treated

September 11, 2011

Aquatechnex assisted Idaho State Department of Agriculture in treating Eurasian Milfoil infestations in three marinas in the Hope/Elisport Bay area on Thursday September 8th as was noted in this blog prior.  There are no swimming restrictions on the water in the area, an irrigation and potable water use restriction within these treatment areas remains current until ISDA water sampling indicates that levels have dropped below label limitations on those activities.  This generally happens within a few days.  ISDA will be informing us on this and we will be posting the all clear on this site as soon as we have that news.


Eurasian Milfoil Treatments Set for Week After Labor Day

August 30, 2011

Aquatechnex biologists will be treating approximately 33 acres of Lake Pend Oreille in the Elisport area this coming week.  This work will be at the direction of the Idaho Department of Agriculture’s Eurasian Milfoil program.  ISDA staff have been surveying the lake and have noted that milfoil densities in this area are such that treatment is warrented.

The herbicide to be used will be triclopyr, a selective systemic product that is target specific for this aquatic weed.  There are water use restrictions that will be in place within the treatment areas for irrigation and potable use until levels drop below labeled restrictions.  This generally takes from a few days to a week.  ISDA will be performing water sampling to monitor these levels and will alert us when we can post an all clear on this web site.

It is anticipated that this treatment will occur on Thursday September 8 with a planned start time of near 11 am.  This may be modified based on weather conditions and interested parties should check this web site again Wednesday evening.  Any questions can be forwarded to tmcnabb@aquatechnex.com


Article on 2006 Sonar Herbicide Treatments Posted at Aquatechnex

We have posted an article on the results of the 2006 Sonar Aquatic Herbicide Treatments on Lake Pend Oreille at www.aquatechnex.wordpress.com for those that are interested.


Aquatechnex will be delivering public notices for early September Eurasian Milfoil Treatments

August 19, 2011

This coming week, Aquatechnex biologists will be delivering public notification two weeks prior to scheduled treatments to target this noxious aquatic weed in portions of Lake Pend Oreille.  Aquatechnex was selected by the Idaho Department of Agriculture last fall to support their Eurasian Milfoil control efforts in north Idaho and the Lake Pend Oreille System.  We will be providing additional updates here as the dates get closer.
