Weed Treatment
Crystal Lake is treated for invasive species, including Eurasian Milfoil annually. It usually takes at least 2 weeks to see results of this application. The treatment attacks specific spots where the plant has returned and is not an entire lake application
The 2,4-D is a growth hormone mimic, meaning that it causes susceptible plants to grow faster than usual and otherwise disrupts normal growth processes such as membrane protein synthesis, RNA production, and overall stability and integrity of plasma membranes. Typically you see a flush of growth first, often times curled/twisting (epinasty) on the new growth where the hormones work, and then a browning and withering from 2-3 weeks after treatment because the increased cell proliferation increases and the plant's vascular system becomes blocked due to excessive cell division and the resulting growth crushes the vascular transport system. Basically the plants grow so fast that the support structures and transport systems cannot be made fast enough to keep the plant together.
Restrictions are no swimming in treated or adjacent areas for 24 hours from application. No water to be used for drinking or irrigation for 21 days. No restrictions on fishing.
5-Year Management Plan
The upcoming application to control Eurasian Milfoil weeds and other costs are expensive. By becoming a CLAA member you will help support your community. Please consider becoming a Crystal Club member, the additional donation will go a long way this year to conquer invasive species and remain within our budget.
Eurasian Watermilfoil Information
A Eurasian Watermilfoil manual removal instructional video is now available for public viewing on YouTube. Specialists talks about the proper techniques used to remove above-water and underwater milfoil by hand.
