Sucking insects use feeding tubes to feed from phloem (e.g. aphids, leafhoppers, scales and whiteflies), or to suck cell contents (e.g. thrips and mites). An insecticide is more effective if it is in the compartment the insect feeds from. The physicochemical properties of the insecticide determine how it is distributed throughout the plant. [11 ...
Health effects of pesticides may be acute or delayed in those who are exposed. [1] Acute effects can include pesticide poisoning, which may be a medical emergency. [2] Strong evidence exists for other, long-term negative health outcomes from pesticide exposure including birth defects, fetal death, [3] neurodevelopmental disorder, [4] cancer, and neurologic illness including Parkinson's disease ...
The pesticide manual provides much information on pesticides. [6] [7] Many of the insecticides in the list are not in use. The developer of a pesticide applies for a common name when they intend to sell it, but some nevertheless do not reach the market. Many insecticides have been banned or otherwise withdrawn from the market over the decades.

[5]The Food and Agriculture Organization (FAO) has defined pesticide as: . any substance or mixture of substances intended for preventing, destroying, or controlling any pest, including vectors of human or animal disease, unwanted species of plants or animals, causing harm during or otherwise interfering with the ...
Pesticide poisoning is an important occupational health issue because pesticides are used in a large number of industries, which puts many different categories of workers at risk. Extensive use puts agricultural workers in particular at increased risk for pesticide illnesses.
Carbofuran is a carbamate insecticide, banned in the US, the EU and Canada but still widely used in South America, Australia and Asia. [6] It is a systemic insecticide, which means that the plant absorbs it through the roots, and from there the plant distributes it throughout its organs where insecticidal concentrations are attained.
Endosulfan is an organochlorine insecticide and acaricide, which acts by blocking the GABA-gated chloride channel of the insect (IRAC group 2A). [2] It became highly controversial [3] due to its acute toxicity, potential for bioaccumulation, and role as an endocrine disruptor.
Dimethoate is a widely used organophosphate insecticide and acaricide.It was patented and introduced in the 1950s by American Cyanamid.Like other organophosphates, dimethoate is an acetylcholinesterase inhibitor which disables cholinesterase, an enzyme essential for central nervous system function.
