Question

Armor needs to spray 2,4-D in his crop field. What does it indicate?

Answer 1

2,4-D is one among the oldest and most generally available herbicides and defoliants within the world, having been commercially available since 1945, and is now produced by many chemical companies since the patent thereon has long ago expired. It is often found in numerous commercial lawn herbicide mixtures and is widely used as a weedkiller on cereal crops, pastures, and orchards.

Complete answer:
2,4-Dichlorophenoxyacetic acid was introduced as a phytohormone. It's widely used as an herbicide within the us. It's used as an herbicide to regulate broadleaf plants and as a plant phytohormone. it's also wants to control weeds in crop fields. This herbicide mimics the action of auxin and results in uncontrolled growth of broadleaf which leads to death of the susceptible plant. The derivatives of two, 4-D including esters, amides, and salts.
All the novel auxins were developed as a part of a clandestine wartime effort to make chemical operations agents and/or selective herbicides; although 2,4-D wasn't used in this manner during the war. Britain and therefore the US were trying to find a chemical to starve Germany and Japan into submission by killing their potato and rice crops, but 2,4-D was found to be ineffective for that purpose because both crops are tolerant of it.

Note:
William Templeman found that when indole-3-acetic acid (IAA), the present auxin, was used at high concentrations, it could stop plant growth. In 1940, he published his finding that IAA killed broadleaf plants within a cereal field. MCPA was discovered at that time by his ICI group.
