The City of Encinitas uses a pesticide on the grass where our children and pets play. The same pesticide other countries have banned as a result of the related negative health impacts to humans and the environment.

What is being sprayed?

2,4-D (2,4-Dichlorophenoxyacetic acid) is the active ingredient in the following pesticides and herbicides used on athletic fields, golf courses, landscaping, rights-of-way, and various crops in Encinitas. The airborne chemical can even travel significant distances, damaging plants downwind, and contaminating homes.



Fusilade II

What is the history of 2,4-D?

In 2015, the International Agency for Research on Cancer declared 2,4-D a possible human carcinogen.

What is Q-4?

Q-4 is a “selective” herbicide that is applied directly to the grass and turf in the parks.

Scientific studies show that 2,4-D applied to lawns drifts and is tracked indoors where it settles in dust, air and surfaces and may remain for up to a year in carpets.

What is DRIVE - XLR8?

DRIVE – XLR8 is a post emergent selective herbicide that contains and kills crabgrass and many broadleaf weeds such as clover, dandelion, foxtail, wild violet and more.

What is Glyphosate?
Glyphosate is the active ingredient in weed killer products such as RoundUp™. Glyphosate products are one of the most widely used weed killers worldwide on farms, schools, parks, athletic fields, golf courses, home gardens and lawns.
Is it true that pesticide manufacturers have reward programs for farmers and landscape maintenance contractors?

Yes! You can see an example here.

2,4-D was first used in the United States in the 1940s under the name Agent Orange, an herbicide used during the Vietnam War, which contained contained both 2,4-D and 2,4,5-T. Dioxin, a by-product of 2,4,5-T, led to the ban of Agent Orange.

The International Agency for Research on Cancer declared 2, 4-D a possible human carcinogen based on evidence that it damages human cells and, in a number of studies, caused cancer in laboratory animals. 2,4-D sticks around in the environment. Depending on the formulation, it can drift through the air from the fields where it is sprayed or be tracked inside homes by pets or children. By the EPA’s own measure, 2,4-D has already been detected in groundwater and surface water, as well as in drinking water. Australian scientists reported in 2012 that it was found in more than 90 percent of samples taken from agricultural catchments bordering the Great Barrier Reef—bad news for many fish, for whom the herbicide can be toxic. It can also poison small mammals, including dogs who can ingest it after eating grass treated with 2,4-D (3).
