Organic Farming Crises
Theory: DDT stand for dichlorodiphenyltrichloroethane and is used as an insecticide and it is used for removing insects from crops, they are used by people called biological farmers. Molecular formula | Molar mass | Density | Melting Point | Boiling point | C14H9Cl5 | 354.49 g/mol | 0.99 g/cm³ | 108.5 °C | 260 °C |
DDT was not formed naturally it was made by the reaction between chloral (CCl3CHO) and chlorobenzene (C6H5Cl) with the presence of sulphuric acid which acts as a catalyst.

DDT is a chemical used to kill bugs or insects that can harm farmers crops. It was used in USA a lot and killed many animals as they got affected with the use of DDT and now it is considered illegal to use in USA after the death of so many animals due to the use of DDT. This activity was going in USA till 1972, until it was strictly banned by the United States Environmental Protection Agency (EPA). However, DDT has not been completely banned as long it is used legally it can be used for pest control. Here is a graph that shows the use of DDT. This is the tie when DDT was being used to cure diseases like malaria because there are less cases of malaria. My hypothesis is that the use of DDT stopped in Ceylon and that’s when the cases took peak.

Its purpose was to destroy forests and enemy crops during the war (Agent Orange, 2015).
