ORGANIC CHEMISTRY IN FERTILIZERS… Fertilizers Organic Inorgnanic
Fertilizer is any organic or inorganic material of natural or Fertilizers synthetic origin that is added to a soil to supply one or more plant nutrients essential to the growth of plants.Mined inorganic fertilizers have been used for many centuries, whereaschemically synthesized inorganic fertilizers were only widely developed during theindustrial revolution. Increased understanding and use of fertilizers wereimportant parts of the industrial Green Revolution of the 20th century. Eg:NH4NO3and CO(NH2)2. Those fertilizers which are derived from organic plant Organic Fertilizers or animal matter is called as Organic fertilizer. Eg: Urea, manure, compost, etc. Those fertilizers which are derived from inorganic Inorganic Fertilizers matter is called as inorganic fertilizer. Eg: NH4NO3, Ca(NO3)2, KNO3, etc.
UREA Urea or carbamide is an organic compound with the chemical formula CO(NH2)2. More than 90% of world The molecule has two production of urea is —NH2 groups joined destined for use as a by a carbonyl (C=O) nitrogen-release fertilizer. functional group. Urea has the highest nitrogen content of all solid nitrogenous It is a colorless, odorless fertilizers in common use.solid, although the ammonia Therefore, it has thethat it gives off in the lowest transportationpresence of water, including costs per unit of nitrogenwater vapor in the air, has a nutrient.strong odor. It is highlysoluble in water andpractically non-toxic
ORGANIC CHEMISTRY IN PESTICIDE… PesticideHerbicide Insecticide Fungicide
Any substance intended for preventing, destroying or Pesticide controlling any pest, including vectors of human or animal disease, unwanted species of plants or animalscausing harm and interfering with the production, processing, storage, transportor marketing of food, agricultural commodities or substances which may be givento animals for the control of pests on their bodies. Also used as substancesapplied to crops either before or after harvest to protect the commodity fromdeterioration during storage and transport. Herbicides, also commonly known as weedkillers, are pesticides used to kill unwanted plants. Selective herbicides Herbicide kill specific targets, while leaving the desired crop relatively unharmed. An insecticide is a pesticide used against insects.Insecticide Insecticides are used in agriculture, medicine, industry and the household. Fungicides are chemical compounds or biological organisms used to kill or inhibit fungi or fungal spores. Funguss are a tiny plantlike organism that gets its Fungicide nourishment from other living or nonliving things. It can cause serious damage in produce, resulting in critical losses of yield, quality and profit.
HERBICIDEHerbicides are those One of thepesticides which are importantused to kill unwanted examples ofplants or weeds Herbicide is 2,4-Some plants produce dichlorophennatural herbicides, oxyaceticsuch as the genus acid.Juglans (walnuts).Herbicides have widely variable toxicity. In additionto acute toxicity from high exposure levels, there isconcern of possible carcinogenicity.
2,4-DICHLOROPHENOXYACETIC ACID 2,4-Dichlorophenoxyacetic acid is a common systemic herbicide used in the control of broadleaf weeds. It is one of the most widely used herbicide in the world, and the third most commonly used in North America. In 1987, the International Agency for Research on Cancer (IARC) concluded that 2,4- dichlorophenoxyacetic acid be classified as a class 2B carcinogen - "possibly carcinogenic to humans".
