  1. Insecticide subgroup Summary NorBaRAG 2018

  2. Pollen beetle monitoring • Niels Jakob Jacobsen, ADAMA Northern Europe • 2017 pollen beetle monitoring in Nordics, Baltic and central zone • Nordics: • No kdr findings • Biscaya (neonicotinoid): slight fall in efficacy in the last few years • Karate (pyrethroid): slight increase in efficacy (used less) • Mavrik (pyrethoid): constant • Central: Biscaya and Karate decrease, mavrik constant • Yield not affected by PB

  3. Monitoring in Sweden • Lovisa Eriksson, Jordbruksverket • Pollen beetles: • 14 sites (Sweden) • Resistance against karate • Nordic/Baltic: Biscaya slight fall, Mospilan still good • Cabbage seed weevils: • 4 sites (Sweden) • Highly susceptible to all 3 products (M, K, B) • CSFB: • Low incidence of kdr

  4. Resistance of strawberry blossom weevils • JarmoKetola, LUKE • Raspberry and strawberry pest • Lambda-cyhalothin • Collection sites in conventional and organic farms • Indications of resistance • Difference between conventional and organic farm weevils

  5. Resistance handling in Germany • Udo Heimbach, Julius-Kuehn Institute • Expert committee on pesticide resistance • Advisors, JKI, companies, reg authorities, PPP retailers • Knowledge sharing • Harmonizing of tests, protocols • Coordinate monitoring activities • Resistance strategies for: • Oilseed rape • Potatoes • Cereals

  6. Resistance of cabbage stem flea beetles • DorteHøjlandCastberg • 15 samples from DNK, 15 samples from SWE • Tested for kdr pyrethoid resistance • Results: • Kdr “non-existing” in SWE • Low kdr and resistance levels East and North of Denmark • High levels in South of Denmark • Multiple factors involved

  7. Moving forward • How to take full advantage of the NorBaRAG insecticide group? • Sharing knowledge: • Dose response curve concentrations for insect species • Collection guide • Cooperation partners • List of participants and what we do • Mutual data compilation on homepage
