Geigy Pharmaceutical was awarded the Nobel Prize in Physiology or Medicine in 1948 "for his discovery of the high efficiency of DDT as a contact poison against several arthropods. After the war‚ DDT was made available for use as an agricultural insecticide‚ and soon its production and use skyrocketed.

Malathion shows little cause of increased likelihood to adverse health effects. Compared to other organophosphate insecticides Malathion has relatively low toxicity to humans‚ other mammals‚ and birds‚ which is why Malathion is the preferred method used to kill mosquitoes and prevent West Nile Virus (Agency for Toxic Substances & Disease Registry‚ 2007).

Endosulfan Endosulfan is an off-patent organochlorine insecticide and acaricide. This colourless solid has emerged as a highly controversial agrichemical[1] due to its acute toxicity‚ potential for bioaccumulation‚ and role as an endocrine disruptor. It is banned in more than 63 countries‚ including the European Union‚ Australia and New Zealand‚ and other Asian and West African nations‚[2] and being phased out in the United States‚[3][4] Brazil[5] and Canada.[6] It is still used extensively in many

Cotton‚ like many other plants‚ has a variety of pests which harm the plant and lower the amount of cotton a farmer produces. To combat this issue researchers have genetically modified cotton so that the plant excretes a toxin that is harmful to many of these pests‚ like Bollworms. BT Cotton stands for Bacillus thuringiensis‚ a bacterium. This bacterium produces and endotoxin‚ which is lethal to many of the pests. This toxin can be very useful because helpful insects are left unharmed.

Making use of radish extract as an effective alternative method of getting rid of insects and pests like worms‚ ants‚ and aphids was studied in this research project. The purpose of this experiment is to prove that radish extract can be used as an insecticide. The researchers first gathered all the materials needed to complete the experimentation. First washed‚ sliced‚ and pounded the radish tubers using the mortar and pestle. Then the researchers extracted it by using a clean strainer‚ strained
