Let’s begin!

? What Is a Pre Emergent Herbicide?

A pre emergent herbicide is a herbicide used before weeds come out of the soil.
“Pre” means before, and “emergent” means coming out.

? Why use a pre emergent herbicide?

• It stops weed seeds from growing
• It keeps the field clean from the beginning
• Helps crops grow with less competition
• Saves time and money later because fewer weeds grow

? When to use a pre emergent herbicide?

• Right after sowing seeds
• Before weeds appear
• When soil has enough moisture

? Simple Example

If you sow your crop today and spray a pre emergent herbicide, many weed seeds will not grow at all.

This gives your crop a clean and healthy start.

? What Is a Post Emergent Herbicide?

A post emergent herbicide is a herbicide used after weeds have already grown.
“Post” means after, and “emergent” means coming out.

? Why use a post emergent herbicide?

• It kills weeds that are already visible
• Useful when weeds escape the first spray
• Helps control strong and fast-growing weeds
• Can target specific weeds without harming crops (depending on product)

? When to use a post emergent herbicide?

• When weeds are young and actively growing
• When the crop is stable and safe for spraying
• When there are visible weed patches

? Simple Example

If weeds start growing in your field after 15–20 days of sowing, a post emergent herbicide will help you control them.

? Difference Between Pre Emergent Herbicide and Post Emergent Herbicide

Both are important.
Farmers often use both types in different stages for best results.
