Effective weed management in Indian soybean crops requires herbicides adapted to monsoon patterns and local weed flora. The best herbicide for soybean in India must control both kharif-season grasses and broadleaf weeds while maintaining crop safety in black cotton soils. This guide evaluates herbicides approved by the Central Insecticides Board for Maharashtra, Madhya Pradesh, and Rajasthan soybean belts. Discover cost-effective solutions for Dhaincha, Jungli Jowar, and Motha grass control. Best Herbicides for Soybean in India 1. Pendimethalin 30% EC – pre-emergence Pendimethalin 30% EC is the most-used Soybean Herbicide in India for early weed control. This dinitroaniline herbicide prevents weed germination for 6-8 weeks. Apply 3.3-4.4 L/ha pre-planting in Maharashtrian vertisols. Controls Tandla (Trianthema portulacastrum) effectively. ICAR trials show 85% weed suppression in MP soybean fields. Compatible with seed treatment. 2. Imazethapyr 10% SL – post-emergence Imazethapyr 10% SL offers broad-spectrum Soybean Herbicide control in rainfed conditions. Targets Chulai (Amaranthus viridis) and Bhurundha. Use 750-1000 ml/ha with surfactant at 20-25 DAS. Safe for soybean varieties like JS-335. RAU Pusa reports 92% control of broadleaf weeds without crop phytotoxicity. 3. Quizalofop-ethyl 5% EC – grassy weeds Quizalofop-ethyl 5% EC is the top Soybean Herbicide for controlling Sawank (Echinochloa colona) and Kodu (Dactyloctenium aegyptium). Apply 500-750 ml/ha at 3-4 leaf stage. Mix with UPOIL for better absorption. MPKV Rahuri trials show 96% suppression of monsoon grasses in Vidarbha region. 4. Fomesafen 25% SC – broadleaf control Fomesafen 25% SC is a contact Soybean Herbicide for hard-to-kill weeds like Chhota Kateru (Xanthium strumarium). Use 1.0-1.2 L/ha with NIS adjuvant. Apply before flowering stage. JNKVV Jabalpur recommends this Soybean Herbicide for Bundelkhand region's problematic weeds. 5. Propaquizafop 10% EC – new generation Propaquizafop 10% EC controls resistant grasses like Jangli Jowar (Sorghum halepense) in soybean fields. Apply 500-600 ml/ha with MSO. Rainfast within 2 hours post-application. PDKV Akola trials demonstrate 89% control of perennial grasses in Marathwada. 6. Metribuzin 70% WP – residual action Metribuzin 70% WP provides dual pre-post Soybean Herbicide action in heavy soils. Controls Motha (Cyperus rotundus) effectively. Use 300-400 g/ha with proper soil moisture. Best for Rajasthan's clay-loam soils. CAZRI Jodhpur reports 78% sedge control with minimal carryover effect. 7. Targa Super – quizalofop-p-tefuryl Targa Super 5% EC is a premium Soybean Herbicide for mixed weed flora. Fast-acting formula visible in 72 hours. Apply 800-1000 ml/ha with UPOIL. Compatible with micronutrient sprays. Gujarat Agricultural University recommends for Saurashtra's coastal soybean areas. 8. Topramezone 35% SC – new chemistry Topramezone 35% SC offers HPPD-inhibitor Soybean Herbicide action for resistant weeds. Safe for intercropping systems. Use 100-120 ml/ha with adjuvant. Controls Kans Grass (Saccharum spontaneum). IIPR trials show 85% broad-spectrum control in UP soybean fields. 9. Weedmaruthi – organic neem-based Weedmaruthi provides natural Soybean Herbicide action using neem cake derivatives. Suitable for organic farming. Apply 5-7 kg/acre during sowing. Suppresses weed germination through allelopathy. NABARD-approved for PKV Akola's organic soybean clusters. 10. Clodinafop 15% + Metribuzin 35% WG – combo This combination Soybean Herbicide controls both grasses and broadleaves in single application. Apply 300-400 g/ha at 15-20 DAS. Cost-effective for smallholders. DGR Jalgaon trials show 82% mixed weed control in Khandesh region. Buyer’s Tips for Soybean Herbicides in India Match Herbicide to Soil Type Choose Soybean Herbicide formulations based on black soil vs. red soil water retention capacity. Monitor Monsoon Timing Apply pre-emergent Soybean Herbicide before first monsoon showers for activation. Check CIBRC Approval Verify Soybean Herbicide registration for your state (MH/MP/RJ/GJ). Use Adjuvants Properly Add UPOIL (2%) or Teepol (0.2%) to Soybean Herbicide sprays for hard water areas. Manage Resistance Rotate Soybean Herbicide MOA between ACCase inhibitors and ALS inhibitors. Consider Intercrops Select Soybean Herbicide safe for common intercrops like tur or urad. Follow PHI Guidelines Observe 45-60 day pre-harvest interval for Soybean Herbicide applications. Conclusion For most Indian soybean farmers, Pendimethalin 30% EC remains the best Soybean Herbicide foundation for monsoon weed control, followed by post-emergent Quizalofop-ethyl 5% EC for grassy weeds. Newer options like Propaquizafop 10% EC offer solutions for resistant biotypes. Always calibrate sprayers (knapsack/tractor) before applying Soybean Herbicide and follow integrated weed management combining cultural practices with chemical control.
