Resistance profile for Fenvalerate

Resistance Summary
Resistance Factor (RF):
RF = LC50 (field isolate) / LC50 (susceptible isolate)
Resistance Level (RL):
Level RF Range
Susceptible (S)< 1.4
I1.5 – 5
II5.1 – 25
III26 – 40
IV> 41

Note: Resistance factor (RF) thresholds are based on published studies and may vary across systems. LC50 of susceptible isolates is not location-specific and therefore not directly comparable across studies.
