Historical Background• The use of pesticide was first utilized in 2500BC.• The first pesticide was sulfur used about 4,500
years ago. • By 15th century, toxic chemicals were applied to kill
pests.• In 17th century, nicotine sulfate was extracted.• In 19th century, the introduction of pyrethrum and
rotenone.• In 1939, Paul Müller discovered that DDT was a very
effective insecticide.• In 1940 manufacturers produce synthetic pesticides• Pesticide use has increased 50-fold since 1950.• In the 1960s, it was discovered that DDT was
becoming a treat in biodiversity.

Raw Materials
• Inert Ingredients
• Active Ingredients
![Page 11: CPI Agrichemical Industry](https://reader037.fdocuments.in/reader037/viewer/2022102716/5469d34cb4af9f8e0f8b4ac0/html5/thumbnails/11.jpg)
Inert Ingredients
• It facilitate spraying and coating the target plant; they can also contribute other advantages that are not conferred by the active ingredient alone.
• For liquid, water, kerosene or other petroleum distillate.
• For solid, vegetable matters and talc or calcium carbonate .
![Page 12: CPI Agrichemical Industry](https://reader037.fdocuments.in/reader037/viewer/2022102716/5469d34cb4af9f8e0f8b4ac0/html5/thumbnails/12.jpg)
Active Ingredients
• The active ingredient kills the pests
• Active ingredients were once distilled from natural substances; now they are largely synthesized in a laboratory
![Page 13: CPI Agrichemical Industry](https://reader037.fdocuments.in/reader037/viewer/2022102716/5469d34cb4af9f8e0f8b4ac0/html5/thumbnails/13.jpg)
Harmful Effects
• The publication of Silent Spring by Rachel Carson
• They also kill the pests' natural predators
• DDT is the most widely noted case of a pesticide that caused damage far from the farm.
• Integrated pest management (IPM) was begun in the 1960s in response to the pesticides dilemma.

Manufacturing Process
1. Synthesizing the pesticide
2. Formulating the pesticide
3. Diluting the pesticide
![Page 17: CPI Agrichemical Industry](https://reader037.fdocuments.in/reader037/viewer/2022102716/5469d34cb4af9f8e0f8b4ac0/html5/thumbnails/17.jpg)
Synthesizing the Pesticide
• It is manufactured on a small scale in a laboratory
• If the substance proves viable, production begins in the factory
• Once synthesized, the active ingredient is packaged and sent to a formulator
![Page 18: CPI Agrichemical Industry](https://reader037.fdocuments.in/reader037/viewer/2022102716/5469d34cb4af9f8e0f8b4ac0/html5/thumbnails/18.jpg)
Formulating the pesticide
• Measures out the proper amount, mixes it with carrier if it is to be a liquid pesticide or with inert powders or dry fertilizers if it is to be a dust pesticide
![Page 19: CPI Agrichemical Industry](https://reader037.fdocuments.in/reader037/viewer/2022102716/5469d34cb4af9f8e0f8b4ac0/html5/thumbnails/19.jpg)
Diluting the Pesticide
• The estimated necessary amount is sent to the farmer, who dilutes the emulsified concentrate to create the amount of pesticide desired

Waste Characteristics
• The principal air pollutants are volatile organic compounds (VOC) and particulate matter (PM).
• Liquid effluents resulting from equipment cleaning after batch operation contain toxic organics and pesticide residues.
![Page 26: CPI Agrichemical Industry](https://reader037.fdocuments.in/reader037/viewer/2022102716/5469d34cb4af9f8e0f8b4ac0/html5/thumbnails/26.jpg)
Waste Treatment
• Air Emissions

![Page 27: CPI Agrichemical Industry](https://reader037.fdocuments.in/reader037/viewer/2022102716/5469d34cb4af9f8e0f8b4ac0/html5/thumbnails/27.jpg)
Air Emissions
• Stack gas scrubbing and/or carbon adsorption (for toxic organics).
• Baghouses (for particulate matter removal).
• Combustion is used to destroy toxic organics.
![Page 28: CPI Agrichemical Industry](https://reader037.fdocuments.in/reader037/viewer/2022102716/5469d34cb4af9f8e0f8b4ac0/html5/thumbnails/28.jpg)
Liquid Effluents and Solid Wastes
• Reverse osmosis or ultra-filtration is used to recover and concentrate active ingredients.
• When the wastewater volumes are small and an onsite incinerator is appropriate,
• Contaminated solid wastes are generally incinerated and the flue gases are scrubbed.

Historical Background
• 1730 - Viscount Charles Townshend first studied the improving effects of the four crop rotation system.
• 1842 - Sir John Bennet Lawes produce a practical superphosphate from the phosphates in rock and coprolites.
• 1927 - Erling Johnson developed an industrial method for producing nitrophosphate, also known as the Odda process
• 20th Century - Carl Bosch of IG Farben and Fritz Haber developed the process that enabled nitrogen to be synthesised cheaply into ammonia, for subsequent oxidation into nitrates and nitrites.
