Grader

Professional Weed Control with "Grader"

Managing stubborn weeds in winter oilseed rape or sunflower crops often requires a non-selective, systemic approach. "Grader" by "ZAT Firma Avgust" (Vurnary, Russia) is a potent herbicide based on imazapyr that leaves little room for regrowth. From an operator's perspective, this is a heavy-duty tool: it works systemically, traveling through the plant's vascular system to reach the roots, which is essential for permanent control of perennial weeds.

The key to success here is precision. Since this is a total herbicide, drift management is paramount. During my operations, I prioritize calibrating the sprayer nozzles to ensure uniform coverage. The product comes as an aqueous solution, making it relatively straightforward to mix in the tank, provided you follow proper safety protocols, as it is classified as a Hazard Class 3 product.

Application and Field Performance

• Application Rate: The product is effective at 2–5 liters per hectare. I usually adjust the rate based on the density of the weeds and their development stage.
• Mode of Action: This is a leaf-applied, systemic product. It is highly effective when applied to actively growing foliage, ensuring deep penetration.
• Durability: One application is usually sufficient. Because it has systemic activity, it does not just burn the leaves but kills the weed down to the root system, keeping the field clear for a long time.

Maintenance-wise, always flush your equipment thoroughly. Given the potency of imazapyr, even small residues can be detrimental to non-target crops. If you need a reliable solution for heavy-duty field clearing, "Grader" delivers exactly what it promises, provided you treat it with the respect it deserves as a professional-grade herbicide.
