The weedicide used commonly by the farmers is 2,4-dichlorophenoxyacetic Acid - commonly known as 2, 4-D.

Common Weedicides:
Weedicides are chemicals or substances used to control or eliminate weeds, which are unwanted plants that compete with crops for nutrients, water, and sunlight. There are several common types of weedicides used in crop production management. Some of them include:

1. Glyphosate:
Glyphosate is a broad-spectrum herbicide that is commonly used to control a wide range of annual and perennial weeds. It works by inhibiting an enzyme called EPSP synthase, which is essential for the synthesis of certain amino acids. Glyphosate is effective against both grasses and broadleaf weeds and is widely used in various agricultural and non-agricultural settings.

2. Paraquat:
Paraquat is a non-selective herbicide that is used to control a broad range of weeds. It acts by interfering with the photosynthetic process in plants, leading to their death. Paraquat is often used in combination with other herbicides to enhance weed control efficacy.

3. Atrazine:
Atrazine is a selective herbicide primarily used to control broadleaf weeds and certain grasses in crops such as corn and sugarcane. It inhibits the photosynthetic process in susceptible plants, leading to reduced growth and eventual death.

4. 2,4-D:
2,4-Dichlorophenoxyacetic acid (2,4-D) is a systemic herbicide that is effective against a wide range of broadleaf weeds. It is commonly used in cereal crops, pastures, and lawns. 2,4-D mimics the action of plant growth hormones, causing uncontrolled growth and eventually killing the target weeds.

5. Diquat:
Diquat is a fast-acting non-selective herbicide used to control a variety of annual and perennial weeds. It works by disrupting the cell membranes of plants, leading to rapid desiccation and death. Diquat is often used as a pre-harvest herbicide to facilitate crop desiccation.

6. Pendimethalin:
Pendimethalin is a pre-emergent herbicide that is commonly used to control grasses and certain broadleaf weeds. It forms a barrier in the soil, preventing weed seeds from germinating and emerging. Pendimethalin is often applied before planting or immediately after crop emergence.

7. Metolachlor:
Metolachlor is a selective herbicide used for pre-emergent control of grasses and some broadleaf weeds. It is commonly used in field crops such as corn, soybeans, and cotton. Metolachlor inhibits the growth of susceptible weeds by interfering with protein synthesis.

In conclusion, these are some common weedicides used in crop production management. It is important to use weedicides judiciously and follow the recommended application rates and safety precautions to ensure effective weed control while minimizing environmental impacts.
