Insights on Insecticide Resistance and Monitoring in Agriculture

Insecticide subgroup
 
Summary NorBaRAG 2018
 
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
 
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
 
Resistance of strawberry blossom
weevils
 
Jarmo Ketola, LUKE
Raspberry and strawberry pest
Lambda-cyhalothin
Collection sites in conventional and organic farms
Indications of resistance
Difference between conventional and organic farm weevils
 
 
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
 
Resistance of cabbage stem flea beetles
 
Dorte Højland Castberg
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
 
Moving forward
 
How to take full advantage of the NorBaRAG insecticide group?
