Hitweed Herbicide (Pyrithiobac Sodium 10% EC):
Selective Post-Emergence Weed Control for Cotton
Hitweed Herbicide containing Pyrithiobac Sodium 10% EC is a selective post-emergence herbicide designed to control a wide range of broad-leaf weeds in cotton fields. It belongs to the ALS inhibitor (Acetolactate Synthase inhibitor) group of herbicides, which disrupts the synthesis of essential amino acids required for weed growth. Once absorbed through leaves and roots, the herbicide moves systemically inside the plant, stopping cell division and gradually killing the weeds.
Hitweed is highly effective against difficult weeds that compete with cotton during the early crop stages. By eliminating nutrient competition, it allows cotton plants to establish stronger growth, resulting in better crop stand, improved yield potential, and reduced manual weeding costs. Due to its selective mode of action, it controls weeds without harming the cotton crop when applied at the recommended stage and dosage.

Hitweed Herbicide Features and Benefits
Selective Weed Control
Effectively controls major broad-leaf weeds without harming cotton crops when used at recommended stages.
Systemic Action
Absorbed through leaves and roots and moves inside the plant to stop weed growth from within.
Early Season Weed Management
Controls weeds during the critical crop growth stage when competition can significantly reduce yield.
Reduces Manual Weeding Cost
Helps farmers save labor costs associated with repeated hand weeding.
Improves Crop Yield Potential
By reducing competition for nutrients, sunlight, and water, the cotton crop grows more vigorously.
Compatible in Weed Management Programs
Can be integrated into herbicide rotation strategies to delay herbicide resistance.
Mode of Action
Pyrithiobac Sodium inhibits the Acetolactate Synthase (ALS) enzyme, which is essential for the synthesis of branched-chain amino acids such as valine, leucine, and isoleucine in weeds. When this enzyme is blocked, cell division and plant growth stop. Sensitive weeds stop growing within a few days and gradually die within 2–3 weeks.
Usage and Crop Recommendations
Excel-ready table format:
| Crop | Target Weeds | Dosage / ha | Dilution in Water | Application Stage | Waiting Period |
|---|---|---|---|---|---|
| Cotton | Amaranthus spp., Parthenium hysterophorus, Trianthema monogyna, Digera arvensis, Commelina benghalensis | 500 – 625 ml | 500 L water | 2-4 leaf stage of weeds | Not Applicable |
Application Guidelines
Method of Application
Foliar Spray using a knapsack or power sprayer with flat-fan nozzle for uniform coverage.
Best Application Timing
Apply when weeds are young and actively growing (2-4 leaf stage).
Rain Fastness
Approximately 4–6 hours after spraying.
Spray Coverage
Ensure complete coverage of weeds for maximum effectiveness.
Safety and Compatibility
• Wear protective clothing, gloves, and mask while spraying
• Avoid spraying during strong wind conditions
• Do not mix with incompatible agrochemicals unless recommended
• Keep away from food, feed, and drinking water
