Sumitomo Leader herbicide is a selective, systemic, post-emergence herbicide that is used in wheat crops to control grassy, broad-leaf weeds, and narrow-leaf weeds that compete with crops for nutrients, water, sunlight, and growing space. Leader herbicide works by blocking an essential enzyme needed for weed growth. Sumitomo Leader herbicide strictly targets the wheat crop, and it should be applied early post-emergence. Leader herbicide is absorbed through both the leaves and the roots, providing dual absorption.
Key Features and Benefits of Leader Herbicide:
Broad-Spectrum Weed Control: Leader herbicide targets both narrow-leaf weeds and broad-leaf weeds such as Phalaris minor and Melilotus Alba.
Systemic Action: Sumitomo Leader herbicide destroys weeds from the roots and slows regrowth, saving farmers time and money on manual weeding.
Dual Absorption: Leader herbicide is absorbed through both the leaves and the roots.
Long-Lasting Effect: Sumitomo Leader herbicide is absorbed by plants and stays for a long time, which stops weeds from growing back and keeps fields clean for a longer time.
Leader Herbicide Uses:
Leader herbicide uses include post-emergence weed management in:
Narrow-Leaf Weeds: Phalaris minor (Gulli Danda or Mandusi)
Broadleaf Weeds: Chenopodium species (Bathua), Melilotus alba (Sainji)
Leader Herbicide Dose:
The recommended dose is 13.3 g per acre with 200 ml of the specified surfactant, according to Sumitomo's product guidance.
Crop | Target Weeds | Dose / Acre | Application Method | PHI |
|---|
Wheat | Phalaris minor, Chenopodium album, Melilotus alba | 13.3 g + 200 ml surfactant | Post-emergence foliar spray | 110 days |
Application Window: 30 to 35 days after wheat sowing, preferably when weeds have 2 to 4 leaves.
How to Use Leader Herbicide:
Measure the recommended Sumitomo Leader quantity.
Fill the spray tank partly with clean water.

Compatibility: Use the specified surfactant. Avoid unverified herbicide or pesticide mixtures.
Resistance Management: Rotate herbicides with different modes of action and use appropriate non-chemical weed management practices.
Safety Precautions and Handling:
Wear gloves, a mask, goggles, and protective clothing.
Do not broadcast granules or use a mist blower.
Avoid spray drift onto mustard, gram, and other broadleaf crops.
Do not grow mustard or gram as intercrops in treated wheat.
