Opora

A stable start for soybean and rapeseed crops

When heading out into the field in spring, the main enemy is time and the first wave of weeds. With "Opora" by Himagromarketing, I resolve the issue of crop cleanliness even before the culture emerges from the ground. It is a soil-applied herbicide that works preemptively. As an operator, I value predictability, and the Clomazone active ingredient performs exactly as stated in the regulations.

Application and Performance

The product comes as an emulsifiable concentrate, which is convenient when filling the sprayer; it mixes easily, does not clog nozzles, and doesn't require complex system flushing. Important note: this is a selective systemic herbicide. It is absorbed by weeds at the moment of germination. Based on my experience, the key to success is the quality of soil preparation — the more uniform the surface, the better the protective "screen" created.

• Targeted Control: "Opora" effectively handles weeds problematic for rapeseed and soy: cleavers, field pansy, common lambsquarters, and common chickweed.
• Dosage: I operate within the range of 0.5–1.0 L/ha. I adjust the dosage depending on soil type, opting for the higher rate on heavier soil compositions.
• Efficiency: One pre-emergence treatment gives the crop a 3–5 week head start for active growth without competing for moisture and nutrients.

Keep in mind the 3rd hazard class, which requires standard personal protective equipment. The product does not require repeat passes, which is critical during the short spring working window. "Opora" provides the stability needed to ensure that after emergence, the field remains clean, and the crop focuses on yield rather than survival.
