| ARTICLES RELATED TO Roundup | | | |  Roundup: Encyclopedia II - Plant breeding - DomesticationDomestication of plants is a selection process conducted by humans to produce plants that meet the needs of the farmer and the consumer. The practice is estimated to date back 9,000-11,000 years. Many crops in present day cultivation are the result of domestication in ancient times, about 5,000 years ago in the Old World and 3,000 years ago in the New World. In the Neolithic period, domestication took a minimum of 1,000 years and a maximum of 7,000 years. Today, all of our principal food crops come from domesticated varieties.

| | | | | Roundup: Encyclopedia II - Pesticide - Managing Pest Resistance Pest resistance to a pesticide is commonly managed through pesticide rotation or tankmixing with other pesticides.
Rotation involves alternating among pesticide classes with different modes of action to delay the onset of or mitigate existing pest resistance. Different pesticide classes may be active on different pest sites of action. The U.S. Environmental Agency (EPA or USEPA), for example, designates different classes of fungicides. Pesticide manufacturers may, on product labeling, require that no more than a specified number of co ...

| | | | | Roundup: Encyclopedia II - Pesticide - History Since before 500 BC, humans have used pesticides to prevent damage to their crops. The first known pesticide was sulfur. 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 crysanthemums, and rotenone which is derive ...

| | | | | Roundup: Encyclopedia II - Pesticide - Regulation In the US, all materials intended for sale and use as pesticides must be registered with the EPA. The process may be long, complex and expensive. It requires studies to be performed that indicate whether the material is effective against the intended pest and safe to use. During the registration process, a pesticide label is created which contains directions for the proper use of the material. Use inconsistent with the label is ...
