Argument, a.w., (isopropylamine salt of glyphosate, 480 g/l)

Professional field management with Argument herbicide

When dealing with heavy weed infestations, relying on a systemic glyphosate-based solution is the most efficient route. As an operator, I use the Argument herbicide (480 g/l isopropylamine salt) as my go-to choice for land clearing. Whether it is couch grass (Elymus repens), sow thistle, or a mix of annual and perennial weeds, this non-selective herbicide provides the control needed before planting or as a desiccant.

Operational use and efficiency

Since this is a systemic product, it works best when the target plants are actively growing. In my practice, I utilize it in several distinct ways:

• Pre-emergence cleaning: clearing the field of all weeds before the crop breaks the surface. It is effective on crops like sunflowers, corn, potatoes, and cereals.
• Desiccation: a vital tool for pre-harvest preparation. By applying it correctly, I can ensure uniform grain moisture, which reduces harvest downtime and prevents disease spread.

The product comes as an aqueous solution, which makes preparing the tank mix seamless. It doesn't foam excessively or clog nozzles if the loading sequence is followed correctly. It is a non-selective, foliage-applied herbicide, meaning extreme precision is needed to avoid contact with non-target vegetation.

Maintenance and safety standards

Working with a Hazard Class 3 product requires standard safety measures: goggles, gloves, and a respirator are essential. The most important lesson I’ve learned is checking the weather forecast—you need a 4–6 hour window without rain after application to allow the herbicide to penetrate the leaf surface and move into the root system. Results typically appear within 5–7 days, with full weed termination occurring within two weeks.

The manufacturers (Peters & Burg Kft., Yangzhou National Chemical Westjong Company, Zhejiang Jinfanda Biochemical Co., Ltd.) maintain a consistent formulation. Since Argument has no soil activity, it acts as a "reset" button for the field, effectively eliminating existing biomass without leaving residue in the soil that would hinder future growth.
