"Pest-control company Biostadt introduces 'Pyankor,' a novel post-emergent herbicide designed specifically for rice farmers"
On May 22, 2025, Biostadt India Limited introduced a groundbreaking product named 'Pyankor'—a next-generation herbicide designed to revolutionise weed management in paddy cultivation[1]. The launch event, held in Raipur, Chhattisgarh, was attended by Biostadt's senior leadership, channel partners, and international collaborators from LG Chem Life Sciences, South Korea[2].
Pyankor is a post-emergent herbicide, meaning it is applied once the paddy crop has emerged[4]. The herbicide offers farmers an efficient and economical solution to control weeds, thereby improving crop health and yields by removing competition from unwanted plants[4].
One of the standout features of Pyankor is its premium-quality adjuvant, which enables uniform spreading on weed surfaces, ensuring effective coverage[5]. The adjuvant also prevents the solution from being washed away, providing long-lasting weed control.
Pyankor contains Pyribenzoxim 5% EC as its active ingredient[6]. This compound is responsible for the herbicide's ability to halt weed growth within 24 hours of application[6]. Visible yellowing of weeds can be observed within 3 to 5 days of application, with full control over weed growth typically achieved in 7 to 14 days[6].
The herbicide is absorbed into the weed surface within 30 minutes of application[6]. As a next-generation product, it is expected to be rainfast, meaning it retains efficacy even if rain occurs shortly after application, ensuring reliability under typical monsoon conditions encountered in paddy cultivation[4]. However, explicit data on rainfastness was not found in the search results.
The recommended application rate for Pyankor is 240 ml per acre[7]. This information, along with detailed data such as the exact active ingredient, application rate, and confirmed rainfastness, can be found in the official product literature or by contacting Biostadt directly.
With the launch of Pyankor, Biostadt continues to demonstrate its commitment to developing innovative crop protection solutions aimed at enhancing paddy productivity by improving weed management at critical crop growth stages[3]. Post-emergent herbicides like Pyankor are generally preferred for managing weeds that emerge simultaneously with or after the crop, allowing farmers to selectively target weeds without harming the paddy plants.

Technology plays a significant role in Pyankor's effectiveness, as the herbicide's premium-quality adjuvant ensures uniform spreading and long-lasting weed control. The active ingredient, Pyribenzoxim 5% EC, is a technological advancement that halts weed growth within 24 hours of application.
