Pesticides are compounds that used to eradicate pests. Insecticide, nematicide, molluscicide, pesticide, avocado, rodenticide, bactericide, insecticide, animalicide, microbicide, fungicide, and lampricide are some examples of these. In many cases, the term "pesticide" refers to the kind of pest that it kills. Pesticides can also be categorized as either biodegradable pesticides, which will be converted into harmless molecules by microorganisms and other living things, or persistent pesticides, whose breakdown could take months or years: For instance, DDT's persistence caused it to build up in the food chain and kill birds of prey at the top of the food chain. Consider chemical pesticides as having a common source or technique of manufacture as another way to think about pesticides.


Neonicotinoids are a group of insecticides that are neuroactive and chemically related to nicotine. The most extensively used insecticide in the world is imidacloprid, which belongs to the neonicotinoid family. Neonicotinoids came under increased investigation for their environmental impact in the late 1990’s and were connected in a number of studies to harmful ecological impacts, such as honey bee Colony Collapse Disorder (CCD) and bird population declines brought on by a decline in insect populations. 2013 saw restrictions on the use of several neonicotinoids by the European Union and a few non-EU nations.

Insecticides made of carbamates and organophosphates both work in a similar ways. By interfering with acetylcholinesterase activity, the enzyme that controls acetylcholine at nerve synapses, they have an impact on the nervous system of target pests (and non-target creatures). Due to this inhibition, the parasympathetic nervous system is overstimulated and synaptic acetylcholine levels rise. These insecticides, most of which were created in the middle of the 20th century, are extremely dangerous. Although being widely used in the past, many older chemicals have been taken off the market because of their negative effects on human health and the environment (e.g. DDT, chlordane, and toxaphene). Many organophosphates are not environmentally persistent.


Amidosulfuron, Flazasulfuron, Metsulfuron-methyl, Rimsulfuron, Sulfometuron-methyl, Terbacil, Nicosulfuron, and Triflusulfuron-methyl are just a few of the sulfonylureas that have been commercialized for weed control. These broad spectrum herbicides work by preventing the enzyme acetoacetate synthase from functioning, killing bugs, weeds, and plants. Crop protection chemicals were usually administered at rates greater than 1 kg/ha (0.89 lb/acre) in the 1960’s, but sulfonylureas only require 1% as much substance to produce the same effect.

Bio pesticides

Bio pesticides are specific forms of insecticides made from natural substances like bacteria, plants, animals, and minerals. Canola oil and baking soda are two examples of bio pesticides that have pesticide uses.

Bio pesticides are categorized into three main groups: bacteria, entomopathogenic fungi, or viruses are the main components of microbial insecticides (and sometimes includes the metabolites that bacteria or fungi produce). Despite being multicellular, entomopathogenic nematodes are frequently categorized as microbial insecticides. Pests and microbiological diseases can be controlled (or monitored, in the case of pheromones), using biochemical pesticides as well as herbal pesticides. Genetic material from different species has been included into the genetic makeup of plant-incorporated protectants (PIPs) (i.e. GM crops). Their use is debatable, particularly in several European nations.


Pesticides are used to manage organisms that are deemed pernicious or damaging to their eradicate mosquitoes that may spread diseases environment. For instance, they are employed to like West Nile virus, yellow fever, and malaria, all of which have the potential to be fatal. Moreover, they can eliminate ants, wasps, and bees that might trigger allergic reactions. Animals can be protected by insecticides against diseases that parasites like fleas can transmit. Pesticides can stop human illness that could be brought on by contaminated produce or moldy food. Herbicides can be used to get rid of trees, brush, and weeds along the road. They can also eliminate invasive weeds that could harm the environment. Herbicides are frequently used in ponds and lakes to prevent algae and other plants like water grasses that can obstruct swimming and fishing and make the water smell or look bad. Termites and mound are two pests that can harm structures like houses if they are not controlled. To control rodents and insects that infest food, such as grain, pesticides are used in grocery shops and food storage facilities each application of a pesticide entails some danger.
