In Stockton, California managers have been trying to keep the water hyacinth that washes in from the Delta under control with herbicide treatments. Unfortunately even after 15 applications, the hyacinth has extended beyond the level of control. Port officials say a state spraying program failed to control the hyacinth, so they contracted with a Bay
Clay Township Michigan residents vote against a broad-spectrum weed killer as part of a scheduled herbicide treatment. The spray of concern was glyphosate, which is a systemic herbicide used to kill weeds that absorbs into an unwanted plant, right down to its roots.

Hydrilla’s roots run deep in Florida. After a Gulf Coast aquarium dealer had the plant shipped from Sri Lanka in the early 1950s, the stringy nuisance has cost government agencies countless millions.

About 120-150 acres of the 910-acre lake is still covered by 25,000 tonnes of grass. Executives of Harvins Constructions Private Limited, the company tasked with de-weeding
Work to restore Lake Horowhenua’s environmental health, which has been progressing well since the establishment of the Lake Horowhenua Accord in 2013, will increase in momentum later this year following a High Court decision.

Plastic is killing 40 % of young sea turtles, shocking new research has shown. Baby turtles are almost four times more likely to be killed by ingesting plastic waste compared to adults.

Leave the weed cutting on lakes to the professionals, was one common theme at Thursday morning’s Cayuga County Water Quality Management Agency meeting in New York. Invasive species have proved to be particularly difficult to manage this year, and in areas such as Cayuga Lake and Skaneateles Lake, agencies have found property owners with good
The ongoing battle against aquatic weeds on Kenosha County’s inland lakes is getting tougher as one of the most invasive species is developing an herbicide-resistant strain, and ongoing drought changes the landscape of the lakes. Without artificial control methods, the lake weeds would make Camp Lake and Paddock Lake, among others difficult to navigate as
The winter phase of the milfoil control program on Osoyoos Lake in British Columbia, Canada, got underway last week as water temperatures continued to cool. Unlike during the summer, when a machine cuts and harvests the tops of the invasive weed, between October and April a rototiller is used to pull the plant up by
Since milfoil was first discovered in Lake George in 1985, roughly 200 locations where it is growing in the lake have been found. Officials have been able to manage the invasive Eurasian watermilfoil, which competes with and can displace native aquatic plants. Now, officials are hopeful that a three-year push to remove milfoil from Lake
