Question

Define
a) Dalapon
b) Metolachlor

Answer 1

Hint: Weeds are referred to as unwanted plants which grow along with the main plants and compete with minerals, water, nutrients etc. Weedicides are also called herbicides, which are defined as chemicals which kill these weeds. Herbicides can be classified as selective (only kill certain types of plants) or non-selective (kill all types of plants).

Complete answer:
As discussed above, weedicides or herbicides are used to get rid of unwanted weeds. Weedicides are chemicals which help to kill the weeds which act like manure. Different plants have varying degrees of susceptibility to different mechanisms of action because of differences in absorption of the chemical and morphology or physiology of the plant. Thus, it’s always important to take care to select the appropriate weedicides for use.

Now when we have understood weedicides, we should discuss the definition of Dalapon and Metolachlor:
• Dalapon: is classified as herbicide which used to control perennial grasses and is used in the field of sugar beets and sugarcane.
• Metolachlor is also an herbicide. But belongs to the family chloroacetanilide of herbicides. It is used to control broadleaf weeds and grass.
Some more Examples of weedicides are Xanthium, field bindweed, Quack grass etc.

Additional information:
Use of herbicides always requires technical knowledge regarding choice of particular herbicide, its time of application and safe dose of application for a particular crop. Overdose and underdose of herbicides will make a difference between the failure or success of weed control.

Note: Weedicides are used to kill weeds. Weedicides can be called herbicides.
Also, it’s important to note that Metolachlor is an organic compound which is a member of the chloroacetanilide family of herbicides and is a derivative of aniline. It is highly used to control grasses.
