Pozitiv

Reliable crop protection from the start

Using the 'Pozitiv' herbicide from Sunrise Chemicals Co. Ltd. provides a predictable and effective start for your crops. This system-based herbicide, containing prometryn, works as a soil barrier that prevents weed germination. As an operator, I appreciate its selectivity: when applied at a rate of 2–4 l/ha, the crop—whether soybeans or sunflowers—remains stress-free, while broad-leaved and grass weeds are effectively suppressed.

Field Application Insights

The product comes as a suspension concentrate, which is easy to handle and mix. It integrates well into the spray tank without clogging nozzles, ensuring a smooth and efficient application process. Because it is a pre-emergence soil-applied herbicide, soil moisture is the key factor. In my experience, applying it immediately after sowing to a well-prepared seedbed provides the best results.

• Efficiency: Effectively targets annual broad-leaved and grass weeds before they emerge.
• Safety: Rated with a Class 3 hazard level, it is manageable with standard PPE and lacks the overpowering odors of more aggressive chemicals.
• Consistency: A single application creates a long-lasting protective screen in the topsoil layer.

Keep in mind that this is a pre-emergence tool. It will not eliminate already emerged weeds, so timing is crucial. I have successfully used it on carrots and coriander; the crops emerge clean, eliminating the need for tedious manual weeding or extra mechanical inter-row cultivation. For anyone managing intensive vegetable or industrial crop production, it is a solid, no-nonsense solution.
