Hint: 2, 4-D is that type of chemical which is used to remove unwanted plants as they can be very harmful to the valuable crops which are growing in the nearby areas. Quack grass is also one example of it.

Complete solution:
2, 4-D is known to be a weedicide.
2,4-Dichlorophenoxyacetic acid is a standard general weedkiller utilized in the management of broad-leaved weeds. It's an artificial auxin (plant hormone) and one of the foremost widely used herbicides within the world. 2,4-D is a possible carcinogen per WHO.
2,4-D was one of the ingredients in Agent Orange, a herbicide widely used throughout the Vietnam War. 2,4-D is primarily used as a selective herbicide that kills several terrestrial and aquatic broadleaf weeds, however not grasses. It acts by mimicking the action of the plant growth hormone auxin, which ends up in uncontrolled growth and eventually death in vulnerable plants.
Weed is a wild plant growing wherever it's not wanted and in competition with cultivated plants. Weedicide is the chemical that kills weeds.

Additional Information:
We should keep weedicide away from eatables and animals. Animals should be avoided to graze in the field after spraying weedicides. Knapsack sprayer should be used to spray weedicides, flood jet or flat fan nozzle should be used while spraying. After using weedicide,we should wash and clean the sprayer with soap or detergent powder after spraying is completed.

So, the correct answer is ‘Weedicide’.

Note:
Weedicides are the chemicals that are sprayed over the field to eliminate weeds. They will not show any impact on crop plants. 2 popularly used weedicides are 2,4-D ethyl ester, neem extract, Glyphosate, etc.
