Chapter Two PESTICIDES - RAND- chemical insecticides and environment impacts examples ,Because the broad term pesticide encompasses a diverse collection of sub-stances, an explanation of pesticide taxonomy and nomenclature is warranted. Pesticides can be classified either by target pest or by chemical identity.1 Clas-sification by target pest is perhaps the most familiar. For example, insecticidesPesticides and the Environment - Purdue UniversityThe rate of degradation is affected by the physical, chemical and biological characteristics of the pesticide and the associated environment. The Application Site To maximize pesticide effectiveness and minimize potential environmental concerns, the properties of the pesticide must be compatible with the physical, chemical and biological ...

Potential Health Effects of Pesticides

Because pesticides are toxic, they are also potentially hazardous to humans, animals, other organisms, and the environment. Therefore, people who use pesticides or regularly come in contact with them must understand the relative toxicity, potential health effects, and preventative measures to reduce exposure to the products they use.

The total number of pesticide poisonings in the United States is estimated to be 300 000 year)1 (EPA, 1992). Worldwide, the application of 3 million metric tons of pesticides results in more than 26 million cases of non-fatal pesticide poisonings (Richter, 2002). Of all the pesticide poisonings, about 3 million cases are hospitalized and there are

Rodenticides - National Pesticide Information Center

Warfarin was the first anticoagulant rodenticide. 1 It was registered for use in 1950. 4 Warfarin was discovered in moldy sweet clover that had made a herd of cattle sick. Researchers found that a fungus had converted a chemical that occurs naturally in the clover to a more toxic chemical. 9 Warfarin was widely used until many rodents began to become resistant to it.

Insecticide Mode of Action - BASF

Chemical insecticides have unquestionably been the most successful tools for protecting our crops, structures and livestock from insect pests, and controlling the transmission of many insect-borne diseases. The earliest insecticides were natural substances derived from minerals or toxic plants. The first known example

Less Toxic Insecticides | Home & Garden Information Center

Insecticides may be considered less toxic for several reasons. Generally, they should pose less risk to human and environmental health than conventional insecticides. Many break down rapidly and do not accumulate in the body or environment. Some are very pest specific and do little or …
