In recent years, potato acreage in Poland has fallen due to the changes in the market economy, but as the economy improves it is believed that acreage will increase. Therefore, it is important that the resistance situation be monitored and managed. Chlorfenvinphos, cypermethrin and bensultap will serve as representative standards from their respective chemical groups. To define a resistance management strategy for CPB in Poland. This data can be used to define a discrimination dose.
Resistance is associated with past pesticide use patterns.
This study will be sponsored further by IRAC in 1996. We seek to define the extent of resistance to the standard products and begin the synthesis of a resistance management strategy.
