Pinoxaden Resistance Map, Germany
Description
This dataset provides a geo-referenced resistance map of three key grass weed species, Alopecurus myosuroides (blackgrass), Lolium multiflorum (Italian ryegrass) and Apera spica-venti (bentgrass), to pinoxaden (Mode of Action: ACCase inhibitor, Group A/1) across Germany.
Data were collected through Agris42’s national monitoring program (2019–2025) and complemented with farmer-submitted resistance samples (Bezahlproben). Each population was characterized in biotests under controlled greenhouse conditions. Geographic coordinates are included for each sampling point.
Data Content
- 4,364 characterized grass weed populations (3,631 with approx. location coordinates)
- Resistance classification per population: resistant (<50% efficacy), partial resistance (51–89%), sensitive (>90%)
- Efficacy values (% control at recommended field dose)
- Species identification (ALOMY, APESV, LOLMU) per sample
- Sampling date and growth stage at test
- Regional summaries per federal state available on request
Methodology
- Seeds collected from 1,300+ monitored fields and 6,000+ farmer submissions
- Greenhouse biotests under controlled conditions (GEP-certified facility)
- Spray robot application for standardized dose delivery
- Assessment at growth stages BBCH 13–14 (two-leaf stage)
- Control efficacy scored visually and by biomass at 21 DAS
- Reference sensitive population included in each test batch
- Resistance factor (RF) calculated per population
Context & Typical Use Cases
- Resistance strategy development: Understand the current spread of pinoxaden resistance to design effective resistance management recommendations.
- Market positioning: Identify regions where ACCase A/1 products retain efficacy, or where alternatives are urgently needed.
- R&D prioritization: Locate populations with specific resistance profiles for targeted experiments or follow-up dose-response studies.
- Regulatory data: Use geo-referenced resistance data to support label amendments, efficacy claims, or resistance monitoring submissions.
Extension Options
- Addtional data from other countries
- Custom regional extract (e.g. only NRW or Bavaria)
- Combined with mesosulfuron resistance map (26_A2) for dual-target overview
- Follow-up dose-response experiments on selected populations
- Physical seed samples of characterized populations (on request)
- Annual update subscription (new monitoring season data)
