There are many ways in which pesticide contamination can be prevented such as selecting the appropriate pesticides, proper pesticide mixing, and loading procedures. Preparation of seedbeds and planting allows crops to emerge quickly, potentially reducing early season disease and insect damage that reduces the amount of pesticides needed.
It is also important to dispose of pesticide containers properly and these containers should be triple rinsed. Contaminated containers exposed to rain can leak pesticides into the environment. Pesticides and herbicides contain toxic materials that pose both environmental and human health risks. Humans, animals, aquatic organisms, and plants can be severely threatened by these chemicals. However, with an aggressive march toward the protection of source waters from pesticide and chemical mixtures, as well as improving technology to treat polluted water, there is hope that the flow of pesticides into humans via drinking water can be brought to a tiny trickle for future generations.

Pesticide Facts Pesticides are potentially toxic to humans and can have both acute and chronic health effects, depending on the quantity and the ways in which a person is exposed. Factors Affecting Pesticide Pollution of Water Drainage: Farmland is often well drained and natural drainage is often enhanced by land drains.

Rodenticides Pesticides and the Environment Even though pesticides are sprayed on land, many times, they can make their way into a water source, such as a river, ocean, or pond.
So why are pesticides so harmful to people's health? July 23, AM. Posted By: Robert Beatty. To quote the EPA: " Pesticides derived from natural sources e. Sorry, but if you want to go pesticide free, it's not as easy as buying organic. More over, the level of usage when it comes to approved organic pesticides could very well mean a better general rule of thumb is to go non-organic. But, of course, that would just be a rule of thumb and not an end-all. The only sure route is to know exactly where your food comes from and what pesticides, if any, they use.

Keep the air gap at least twice the diameter of the discharge pipe.
Another method to prevent back-siphoning is to use a backflow prevention device or check valve. Terraces and conservation tillage practices can reduce water runoff and soil erosion.
Ideally, growers should leave as much plant residue as possible on the soil surface to lessen erosion.
Where conservation tillage is not possible, decrease runoff potential by incorporating a low concentration of the pesticide into the soil. In ornamental plantings, consider using mulches to reduce water runoff and soil erosion. Grass buffer strips are very effective in reducing pesticide runoff because they trap sediment containing pesticides and slow runoff water. This allows more runoff water to infiltrate the soil. Leaving untreated grass strips next to streams, ponds, and other sensitive areas can trap much of the pesticide running off treated areas.

Do not apply to saturated or frozen ground. To avoid over-spraying an area and causing drift, check the pesticide label for application precautions or restrictions during windy conditions.
Wind speed, temperature, and humidity all affect the off-target movement of pesticides. Photo: indianapublicmedia. Whenever possible, clean sprayers at the application site at a safe distance from wells, ponds, streams, and storm drains.
Spray the rinsate on the treated area or on another site listed on the pesticide label, or use in the next tank mix. Be sure not to exceed label rates. Be aware of sensitive areas, non-target plants and animals especially endangered species , and damaging effects on habitat. In addition to water sources, sensitive areas include sites where living things could easily be injured by a pesticide. Kentucky bee yard honeybeesuite.
Sometimes pesticides must be deliberately applied to a sensitive area to control a regulated pest such as mosquito abatement or gypsy moth forest treatments. Only well-trained applicators should perform these applications. At other times, the sensitive area may be part of a larger target site. Whenever possible, take special precautions to avoid treating the sensitive area.
Leaving an untreated buffer zone around a sensitive area is a practical way to avoid contaminating it. In still other instances, the sensitive area may be near a site used for mixing and loading, storage, disposal, or equipment washing.
Be very careful to avoid contaminating the sensitive area. Check the label for statements that alert you to special restrictions around sensitive areas. Untreated buffer zone Image: nac. Pesticides may affect non-target organisms directly, causing immediate injury. Or they may produce long-term consequences through environmental pollution. Pesticides may build up in the bodies of animals or in the soil.
For example, if you use the same mixing and loading site or equipment cleaning site over a long period, pesticides are likely to accumulate in the soil. When this occurs, plants and animals that come into contact with the soil may be harmed. Nearly all pesticides can cause plant injury phytotoxicity due to chemical exposure, particularly if applied at too high a rate, at the wrong time, or under unfavorable environmental conditions.
Phytotoxicity can occur on any part of a plant—roots, stems, leaves, flowers, or fruits. Growth regulator type injury ncsupdicblog. Although damage to crops or other nearby plants is primarily caused by drift, it may sometimes be a consequence of surface runoff and root uptake. Besides making honey and beeswax, bees pollinate many fruit, nut, seed, vegetable, and field crops. You must be aware of bee activity when planning pesticide applications.
There has been increasing concern about the decline of bee colonies and the role pesticides may play. Preventing bee loss is the joint responsibility of the applicator, the grower, and the beekeeper. Honey bees may travel as far as 3 miles from their hive to find blooming flowers.
Before applying pesticides labeled as toxic to bees, notify beekeepers in the area so they can protect or move their bee colonies. Pollen-loaded honey bee image: flicker. Bees and other insect pollinators may be exposed to pesticides through different routes, including:. Insecticides are generally toxic to bees, but some are more hazardous than others.
Herbicides are unlikely to harm bees directly. Fungicides do not appear to affect adult bees but may affect larval development. Tank mixing insecticides and fungicides may create a mixture that is more toxic to bees than either product used alone.
Minimize bee kills from insecticide poisoning by following a few basic principles:. Pollinator protective warning label goodnewsnetwork. Pesticides can harm other beneficial insects in addition to bees. These beneficials may be valuable allies in keeping pest populations below damaging levels. A pesticide application often harms the beneficial insect population as much or more than the target pest. So do not spray when beneficial insects are in the target area unless it is unavoidable.
Alternatively, choose a product that does not harm beneficials. Pesticides can harm all kinds of animals. Most injuries occur from the direct effects of acute poisoning.
Fish kills often result from water pollution by a pesticide. Insecticides are the most likely cause, especially when small ponds or streams are under conditions of low water flow or volume.
Bird kills resulting from pesticide exposure may happen in a number of ways. Birds may: ingest pesticide granules, baits, or treated seeds; be exposed directly to sprays; consume treated crops or drink contaminated water; or feed on pesticide-contaminated insects and other prey. Granular or pelleted formulations are a particular concern because birds and other animals often mistake them for food.
Liquid formulations may be safer when birds and other wildlife are in or near the treated area. Remove pet dishes from spray areas. Place baits properly so they are inaccessible to pets, birds, and other wildlife. Animals may also be harmed when they eat plants or animals carrying pesticide residues. Predatory birds or mammals feeding on animals killed by pesticides are a special concern. Pesticide residues remaining on or in the bodies of the dead animal may harm predators.
This is called secondary poisoning. Check the pesticide label for statements about secondary poisoning. The less obvious effects resulting from long-term exposure to pesticides are a major concern.
For example, certain pesticides have been banned because of fish and bird kills and the reproductive failures of several bird species. The most important source of livestock pesticide poisoning has been through contaminated feed, forage, and drinking water. Contamination often occurs as a result of improper or careless transportation, storage, handling, application, or disposal of pesticides.
Certain plants and animals have been identified as endangered or threatened species. Be very careful not to harm these populations. Because all living things are part of a complex, delicately balanced network, removing a single species may set off a chain reaction that affects many other species.
The full significance of extinction is not always readily apparent, and the long-term effects are often difficult to predict. An endangered species is one on the brink of extinction throughout all or a significant part of its range.
A threatened species is one likely to become endangered. A major problem for most wildlife is the destruction of habitat, usually the result of industrial, agricultural, residential, or recreational development. Here is a list of threatened and endangered species in Kentucky. Each state is responsible for implementing the federal Endangered Species Protection Program in cooperation with EPA to protect endangered and threatened species from the harmful effects of pesticides.
Under this program, pesticide products that might harm an endangered species carry a label statement instructing applicators to consult a county bulletin to determine if they must take any special precautionary measures when using the product. EPA develops these bulletins, which identify precautionary measures required in each county where one or more pesticides could affect an endangered or threatened species.
Precautionary measures may include buffer strips, reduced application rates, and timing restrictions. Or an applicator might be prohibited from using the pesticide within the identified habitat altogether. Check with your state, tribe, or territory department of agriculture; local Extension Service; or the EPA website to find out the status of available county bulletins. Image: netrightdaily. An important part of using pesticides legally and responsibly is considering where the pesticide may end up once it leaves the container and whether it might harm or damage non-target sites, plants, or animals.
By applying pesticides at the right time, in the right place, and with the proper application technique, you can greatly reduce—or even prevent—drift, runoff, and leaching. Pesticides that enter groundwater and surface water are hazardous to aquatic organisms, plants, and wildlife. Therefore, you should implement best management practices to prevent runoff and leaching of pesticides.
Non-target organisms include plants, bees and other beneficial insects, fish, wildlife, and livestock. Because of the greater risk of injury to people, plants, and animals, you must know when and how to properly apply pesticides in or near such areas.
Always check the label for statements on endangered and threatened species. You may need to consult a county bulletin that details the procedures for protecting them.
It is your responsibility not only to follow label directions but also to use the best management practices that present the least risk to the environment while achieving effective pest control.
