Glyphosate 62% IPA SL: Non-Selective Systemic Herbicide

Technical Introduction

Glyphosate 62% IPA SL is a non-selective, systemic, broad-spectrum herbicide widely used in agriculture, forestry, and industrial weed management. The active ingredient, Glyphosate, is formulated as the isopropylamine salt (IPA salt) in soluble liquid (SL) form, containing 62% active ingredient.

• Mode of Action (MOA): Inhibits the EPSP synthase enzyme in the shikimic acid pathway, which is essential for the synthesis of aromatic amino acids (phenylalanine, tyrosine, tryptophan).

• Effect: Plant growth stops within hours; visible symptoms (yellowing, wilting, necrosis) appear in 4–10 days. Complete weed death occurs within 2–3 weeks.

• Systemic Action: Absorbed through green leaves and stems, translocated to roots and rhizomes, ensuring control of perennial weeds.

Applications

• Crops & Use Pattern:

  • Pre-plant weed control before sowing major crops (cereals, maize, soybean, cotton, vegetables, etc.).

  • Post-harvest stubble management to kill regrowth and volunteer plants.

  • Orchards & plantations (tea, coffee, sugarcane, banana, citrus, vineyards) for inter-row weed control.

  • Non-crop areas: Roadsides, railways, irrigation channels, industrial zones.

  • Zero-tillage farming: Eliminates weeds before direct seeding.

• Weeds Controlled:

  • Annual weeds – Amaranthus spp., Chenopodium spp., Digitaria spp.

  • Perennial weeds – Cyperus rotundus (nut sedge), Cynodon dactylon (Bermuda grass), Sorghum halepense (Johnson grass).

  • Woody weeds & brush in non-crop areas.

✅ Advantages

• Non-selective broad-spectrum control of >100 grass, sedge, and broadleaf weed species.

• Systemic action ensures complete control of roots and underground rhizomes.

• Environmentally safe: Rapidly inactivated when it contacts soil (microbial degradation), minimal risk of groundwater contamination.

• Versatile: Suitable for agriculture, horticulture, forestry, and industrial uses.

• No soil activity: Can be used before planting crops without affecting germination.

• Cost-effective: Reduces need for repeated mechanical weeding.

❓ FAQ

Q1: What is the difference between Glyphosate 62% IPA SL and other glyphosate formulations?
Glyphosate 62% IPA SL contains the IPA salt form at 62% concentration, offering strong efficacy with good solubility and easy handling compared to 41% formulations.

Q2: Does it affect future crops?
No, Glyphosate has no residual soil activity, so crops can be planted safely after application.

Q3: How long does it take for weeds to die?
Symptoms appear in 4–10 days, and complete control is seen in 2–3 weeks depending on conditions.

Q4: Can it be tank-mixed with other herbicides?
Yes, Glyphosate is often mixed with 2,4-D, Atrazine, or Paraquat for enhanced spectrum and faster burn-down.

Q5: Is Glyphosate safe for crops?
It is non-selective – it kills any green plant tissue it contacts. To protect crops, it must be applied as a pre-plant, directed spray, or shielded spray.
