Elodea eradication in interior Alaska

The second season of herbicide treatment in Chena Slough will begin the week of June 25th. The aquatic herbicide fluridone is being used to eradicate the invasive aquatic plant elodea from the waters of Chena Slough. For more details click on the "Elodea in interior Alaska" tab. 

Herbicide treatment of the invasive elodea infestation in Totchaket Slough will begin this summer! Totchaket Slough is a remote clearwater slough off the Tanana River about 12 miles downstream on Nenana. A dense 230-acre elodea infestation was discovered there in 2015. Stay tuned for more details of our progress on eradicating elodea in the area...

Indoor Gardening Curriculum!

Alaska Agriculture in the Classroom has developed a set of indoor gardening lessons, the Alaska Indoor Gardening Curriculum. In the spring of 2017, AK AITC was awarded a grant from the National Agriculture in the Classroom organization to develop this resource. This work is supported in part by the Agriculture in the Classroom Grant no. 2017-38858 from the USDA National Institute of Food and Agriculture. It was also supported by a grant from the Alaska Farm Bureau. 

This curriculum is a compilation of lessons developed by the Alaska Agriculture in the Classroom program, the National Agriculture in the Classroom (NAITC) organization, and educators throughout Alaska who have developed, reviewed, and piloted many these activities.  Please be patient with us. This is a work in progress, some links are currently in development and will be available soon.

FSWCD has put together a short resource to help producers assess where they stand under the Produce Safety Rule, a portion of the Food Safety Modernization Act (FSMA). This resource shows how to identify a producer’s current exemption status, and then gives an overview of the compliance requirements associated with each exemption status (fully exempt, qualified exempt, and non-exempt).

If you are curious about how a producer’s exemption status is determined and what could cause it to change, or if you would like an idea of the farm safety practices the Produce Safety rule advocates for, then please check out this resource here 

Thanks!

    ELODEA - ALASKA'S FIRST NON-NATIVE INVASIVE AQUATIC PLANT 

Elodea is the first non-native invasive aquatic plant to become established in Alaskan water bodies. It has been found in waterbodies in Anchorage, Cordova, the Kenai Peninsula, the Matanuska-Susitna area, and the Fairbanks area.  It was first detected in the Chena River system in 2009. Surveys conducted in 2011 and 2012 revealed that the lower 10 miles of Chena Slough which runs through North Pole is heavily infested with Elodea. In addition, Chena Lake, at Chena Lakes Recreation Area was found to be infested with Elodea, and a few isolated patches of Elodea were found in the Chena River. In 2015, Totchaket Slough, a slackwater slough located about 60 miles downriver of Fairbanks, was found to be heavily infested as well. 

In Alaska, Elodea infestations in water bodies can be expected to increase sedimentation, displace native vegetation, reduce biodiversity, degrade sensitive fish habitat, and interfere with safe river travel and floatplane operation. Elodea can be spread readily via boats and floatplanes, and because it reproduces vegetatively, a single fragment is all that is needed to start a new infestation. The Fairbanks Elodea Steering Committee propose to use diver-assisted suction dredging in the Chena River, and aquatic herbicide treatments in Chena Slough, Chena Lake, and Totchaket Slough.

Chena Slough Elodea Treatment 

The Elodea infestation in Chena Slough (between Plack Rd crossing and the mouth of Chena Slough) is being treated with the aquatic herbicide fluridone (Sonar^TM). Two years of treatment (2017-2018) have been successfully completed, and it is working! The dense, tangled mats of elodea are all gone. We are monitoring a few small, isolated patches of elodea that were detected in Fall 2018. This year we will conduct the third year of herbicide treatment. Liquid fluridone will be delivered via an herbicide injection system at a concentration of 5-8 parts per billion (ppb) over a 12-16 week period starting on June 24^th, 2019. Pelleted fluridone will be applied by boat in late June and mid-August, 2019. For answers to Frequently Asked Questions about the Chena Slough Elodea Eradication Project click here.  

At the target application rates, there are no restrictions on drinking, swimming, fishing, or livestock/ pet consumption of slough water.

If you use water directly from the slough for irrigation, there are some restrictions that may apply during the treatment period. For plants within the Solanaceae Family such as tomatoes, peppers, tobacco, and potatoes, do not use slough water if the measured fluridone concentration is greater than 5ppb. We recommend that you switch to an alternate irrigation source (e.g. well water) for these crops. 

Water sampling to test the concentration of fluridone in slough water will be carried out weekly over the course of the 2019 season. Please check HERE for updates on slough water fluridone concentration and irrigation restrictions.
