what is 2,4-D?how does it work as herbicide
Answers
Answer:
it's a weedicide for removal of weeds
Answer:
2,4-D kills broadleaf weeds but not most grasses. 2,4-D kills plants by causing the cells in the tissues that carry water and nutrients to divide and grow without stopping. Herbicides that act this way are called auxin-type herbicides.

The Herbicide 2, 4-D
Herbicide effects on broadleaf weed
To most Americans, "2, 4-D" is probably just a mish mash of numbers and letters. But to farmers and gardeners, it is the most widely used herbicide in the world and the third most commonly used in North America.
Chemically, the compound is known as 2,4-Dichlorophenoxyacetic acid and has a molecular formula – for those understand those kinds of things – of C8H6Cl2O3.
It was actually developed as part of the World War II war effort by a British team intent on increasing crop yields by suppressing weeds. It was introduced commercially in 1946 and quickly shot to the top of the usage charts. A 1996 study by the U.S. Department of Agriculture estimated that if 2, 4-D was taken off the market, it would result in $1.6 million in increased food and fiber costs to the consumer.
It was the first "selective" herbicide, meaning that it suppressed "dicots" (plants with two seed leaves, also known as broadleaf plants) while leaving "monocots" alone (plants with one seed leaf or thin leaves). In other words, the herbicide can be sprayed on grasses (like wheat, corn, rice and other cereal crops) – it will leave them alone while it kills broadleaf weeds.
