    Proper Applications of Pesticides, Herbicides, and Fertilizers

    Here's how.

    How do pesticides, herbicides, and fertilizers affect the environment?

    Improper application of pesticides, herbicides, and fertilizers may have an impact on storm water infiltration into groundwater. When these contaminants dissolve in storm water they find their way into the groundwater and then into surface waters, such as ponds, streams, rivers, and lakes.

    Excessive use of fertilizers can lead to eutrophication; eutrophication is excessive richness of nutrients in a lake or other body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen.

    What are the impacts of eutrophication on the environment?

    The impact of eutrophication on the environment and the economy is concerning. When algal blooms form, less sunlight can penetrate the water surface, which results in decreased productivity of underwater plants and depleted oxygen reserves. The lack of oxygen has devastating effects on aquatic life, including fish such as trout and salmon. In addition, some algae produce toxins in the water, further damaging the aquatic ecosystem.

    Economically, operating expenses of public water works increase because of taste and odor issues caused by algal bloom. Fish death and navigational impediments can impact severely the economies of regions dependent on fishing as a source of revenue. Similarly, recreational areas lose business because of slime and weed infestation around lakes and streams.

    What Is a Pesticide?

    A pesticide is a substance (either a chemical or biological agent) that is intended to control pests, or used to protect plants and crops, pesticides can include the following:

    • Herbicide
    • Insecticide
    • Nematicide
    • Molluscicide
    • Piscicide
    • Avicide
    • Rodenticide
    • Bactericide
    • Insect repellent
    • Animal repellent
    • Antimicrobial
    • Fungicide
    • Bioswales
    • Native Plantings
    • Permeable pavement
    • Raingardens

    Sometimes, the aim of the pesticide is to kill or incapacitate the pest. In other cases, it serves as a repellent. In either case, the goal is to prevent or reduce damage to plants and crops and protect the gardener or farmer's income

    What should you do when using pesticides, herbicides, and fertilizers?

    How does pesticides, herbicides, and fertilizers affect human health?

    Increased and incorrect fertilizer use can also result in public health risks. Fertilizers contain heavy metals such as arsenic, lead, mercury and cadmium that can cause serious health problems. Arsenic and lead are believed to cause cancer, and mercury can result in developmental problems. Mercury, lead, and cadmium are slow to break down in soil and thus result in prolonged exposure, making even low levels of these elements hazardous and increasing risk of birth defects, cancer, and reproductive problems.

    Some Guidelines to follow when using pesticides and herbicides include:

    • Always wear appropriate protective clothing.
    • Never wash contaminated clothing with other clothing.
    • Take precautions to prevent spills. For example, close containers tightly after each use, even if you plan to re-open them soon.
    • Store pesticides in their original containers. Never place them in food or beverage containers.
    • Avoid storing pesticides in extreme temperatures. Pesticides should be stored on the property at temperatures between 40-90 °F.
    • Know what nutrient levels a particular plant needs, as well as the current nutrient levels in your soil.
    • Whenever possible, plant native and adapted plants in your garden because their water and fertilizer demands will be less than non-native plant species.
    • Add groundcover plants to your garden to help absorb any extra nitrogen in the soil and to prevent leaching.
    • Always follow the application rates specified on the product labeling.

    What should the half-life of pesticides be?

    The half-life should be printed on the product label. Avoid pesticides with half-lives longer than 21 days. In dealing with pesticides and herbicides at home or on the job, develop a plan for use and safety. At work, only certified applicators may use pesticides and herbicides.

    Mission Statement

    The Kalamazoo Stormwater Working Group (KSWG) is a collaborative effort of outreach and education for our interconnected Municipal Separate Storm Sewer Systems (or MS4s) in the Kalamazoo County area. Rain falls and snow melts across hard and impervious surfaces that do not allow water to soak into the ground. The water flows to storm sewers or catch basins which direct it to a natural surface water body such as a wetland, river, pond or lake. Stormwater runoff carries salts, grass clippings, sediment, fertilizer, oils, pet waste, and other material left on driveways and sidewalks into the catch basins, and unfortunately, they eventually drain to our natural water bodies.

    KSWG partners work together to protect against harmful discharges to the Kalamazoo River and its tributaries.
