Input: Read this: Since before 2000 BC, humans have utilized pesticides to protect their crops. The first known pesticide was elemental sulfur dusting used in ancient Sumer about 4,500 years ago in ancient Mesopotamia. The Rig Veda, which is about 4,000 years old, mentions the use of poisonous plants for pest control. By the 15th century, toxic chemicals such as arsenic, mercury, and lead were being applied to crops to kill pests. In the 17th century, nicotine sulfate was extracted from tobacco leaves for use as an insecticide. The 19th century saw the introduction of two more natural pesticides, pyrethrum, which is derived from chrysanthemums, and rotenone, which is derived from the roots of tropical vegetables. Until the 1950s, arsenic-based pesticides were dominant. Paul Müller discovered that DDT was a very effective insecticide. Organochlorines such as DDT were dominant, but they were replaced in the U.S. by organophosphates and carbamates by 1975. Since then, pyrethrin compounds have become the dominant insecticide. Herbicides became common in the 1960s, led by "triazine and other nitrogen-based compounds, carboxylic acids such as 2,4-dichlorophenoxyacetic acid, and glyphosate".
Question: Where was pyrethrum extracted from in the 17th century?

QUES: When the news arrived in England it caused an outcry. In response, a combined bounty of £1,000 was offered for Every's capture by the Privy Council and East India Company, leading to the first worldwide manhunt in recorded history. The plunder of Aurangzeb's treasure ship had serious consequences for the English East India Company. The furious Mughal Emperor Aurangzeb ordered Sidi Yaqub and Nawab Daud Khan to attack and close four of the company's factories in India and imprison their officers, who were almost lynched by a mob of angry Mughals, blaming them for their countryman's depredations, and threatened to put an end to all English trading in India. To appease Emperor Aurangzeb and particularly his Grand Vizier Asad Khan, Parliament exempted Every from all of the Acts of Grace (pardons) and amnesties it would subsequently issue to other pirates.
