Once administered in a crop that has been invaded by the pest, pesticides start working immediately by affecting the normal biological functions of the organs of the insect. The use of some pesticides may contribute to the development of resistance among the target pests. Pesticides that evaporate into the atmosphere at relatively high temperature can be carried considerable distances thousands of kilometers by the wind to an area of lower temperature, where they condense and are carried back to the ground in rain or snow.

Environmental Threat Analysis on systemic pesticides which contain chemicals such as fipronil and neonicotinoids resulted to a conclusion that they are a threat to the environment. Such loss of activity or toxicity of pesticides is due to both innate chemical properties of the compounds and environmental processes or conditions. Indiscriminate use of chemicals might work for a few years, but after awhile, there aren't enough beneficial soil organisms to hold onto the nutrients. Pesticides are the most thoroughly tested chemicals after drugs in the United States; those used on food requires more than 100 tests to determine a range of potential impacts.

Although pesticides are usually used to kill a particular target pest, many will also kill or harm species that the farmer or other user is not targeting. Plant growth regulators: Substances excluding fertilizers or other plant nutrients that alter the expected growth, flowering, or reproduction rate of plants.

With pesticides, losses have been reduced which makes it easier for farmers to offer their products for lower costs.
