insecticidally การใช้

• The 2-S " alpha " ( or SS ) configuration, known as esfenvalerate, is the most insecticidally active isomer.
• Gamma-cyhalothrin is the most insecticidally active isomer of cyhalothrin / lambda-cyhalothrin, and thus the technical gamma-cyhalothrin product may be considered a refined form of cyhalothrin / lambda-cyhalothrin in that it has been purified by removal of less active and inactive isomers.
