Pesticide application is the practical way in which pesticides (including herbicides, fungicides, insecticides, or nematode control agents) are delivered to their biological targets (e.g. pest organism, crop or other plant).
Mirex is a stomach insecticide, meaning that it must be ingested by the organism in order to poison it. The insecticidal use was focused on Southeastern United States to control fire ants . Approximately 250,000 kg of mirex were applied to fields between 1962 and 1975 (US NRC, 1978).
Pest control is the regulation or management of a species defined as a pest; such as any animal, plant or fungus that impacts adversely on human activities or environment. [1] The human response depends on the importance of the damage done and will range from tolerance, through deterrence and management, to attempts to completely eradicate the ...
A crop-duster spraying pesticide on a field A self-propelled crop sprayer spraying pesticide on a field Pesticides are substances that are used to control pests. They include herbicides, insecticides, nematicides, fungicides, and many others (see table). The most common of these are herbicides, which account for approximately 50% of all pesticide use globally. Most pesticides are used as plant ...
Insecticides are pesticides used to kill insects. [1] They include ovicides and larvicides used against insect eggs and larvae, respectively. The major use of insecticides is in agriculture, but they are also used in home and garden settings, industrial buildings, for vector control, and control of insect parasites of animals and humans.
Pesticides, because they are toxic chemicals meant to kill pest species, can affect non-target species, such as plants, animals and humans. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, because they are sprayed or spread across entire agricultural fields. [1]
Pesticides can disrupt the endocrine systems of fish, affecting their growth, reproduction, and development. Amphibians, which have permeable skin, are highly sensitive to waterborne pesticides, leading to population declines and deformities. Reptiles Reptiles, such as snakes and lizards, can also be affected by pesticide exposure.
The earliest written record of the now-known rotenone-containing plants used for killing leaf-eating caterpillars was in 1848; for centuries, these same plants had been used to poison fish. [4] The active chemical component was first isolated in 1895 by a French botanist, Emmanuel Geoffroy , who called it nicouline , from a specimen of Robinia ...
