NOTES ABOUT THIS BIOTYPE
The initial biotype found in 2006 remained susceptible to clethodim. However other biotypes have been found, in 2016 in two fields- Kfar-Blum (KB) (in peanuts & carrot), Yagur (YG) (in cotton & onion). Sensitive population collected from an organic field in Ayanot (AY). The resistant biotypes were resistant to fluazifop and clethodim.
Molecular analyses showed both ACCase-resistant populations possess an altered target site - Trp2027 to Cys.
