About Herbicides
Herbicides, also called weedicides, are crop protection products used to control weeds — the unwanted plants that compete with crops for nutrients, water, sunlight and space, and directly pull down yield. Weeds are stubborn, and their seeds can survive in the soil for years, germinating whenever conditions turn favourable, which is why timely weed management is essential in every crop. Along with protecting yield, herbicides help farmers cut down heavily on manual weeding labour and save time and cost.
Herbicides are grouped by timing and by selectivity. By timing, pre-emergent herbicides are applied before weed seeds germinate to stop weeds early, while post-emergent herbicides are sprayed on actively growing weeds after they emerge. By selectivity, selective herbicides kill only target weeds while leaving the main crop unharmed, and non-selective herbicides kill almost all green vegetation, making them suited to field clearing, bunds and non-crop areas. Together, these options control annual and perennial grasses, sedges (like nutgrass) and broad-leaved weeds.

Uses & Benefits of Herbicides
-
Effective Weed Control: Controls grasses, sedges and broad-leaved weeds that compete with the crop.
-
Saves Labour and Cost: Reduces dependence on costly and time-consuming manual weeding.
-
Pre- and Post-Emergent Options: Stops weeds before germination or controls them after they emerge.
-
Selective and Non-Selective Choices: Protects the main crop or clears all vegetation as needed.
-
Protects Yield: Keeps fields weed-free so the crop gets full nutrients, water and sunlight.
-
Flexible Application: Sprayed on the weed canopy or soil surface as per label recommendations.
Herbicide Usage Tips
-
Identify the type of weed: grass, sedge or broad-leaved — before choosing an herbicide.
-
Choose the right type: pre-emergent for before germination, post-emergent for actively growing weeds.
- Never use non-selective herbicides on the standing crop unless the label allows, as they can kill the crop too.
- Read and follow the product label for the correct dosage, water volume and application timing.
- Spray evenly over the weed canopy or soil surface and add a spreader/sticker for better coverage.
- Maintain adequate soil moisture for pre-emergent herbicides to work effectively.
- Avoid spraying during strong winds or rainfall to reduce drift and product loss.
Types of Herbicides and What They Do
Herbicides are classified by timing and selectivity:
-
Pre-Emergent Herbicides: Applied before weed germination to stop weeds early.
-
Post-Emergent Herbicides: Sprayed on actively growing weeds after emergence.
-
Selective Herbicides: Control target weeds without harming the main crop.
-
Non-Selective Herbicides: Kill almost all green vegetation, ideal for field clearing and non-crop areas.
