A whole new way to rid the landscape of weed, pest and disease problems was implemented across the world with the chemical revolution during the first part of the twentieth century. A few decades later, a few people began to notice changes in the environment. Most notable among them was Rachel Carson. With the publishing of Silent Spring in 1962, Carson awakened an interest in ecology and the negative implications caused by widespread and indiscriminate use of chemicals, synthetic chemicals, to solve environmental problems. This realization caused many people to question its use and find alternative methods. Numerous state extension offices established a method of managing weed, pest and disease problems, called Integrated Pest Management that sought to use the least harmful practice first, before resorting to a more harmful step. Their aim is to reduce the indiscriminate use of synthetic chemicals in our environment.
