Fungicides are grouped by ‘families’ or ‘classes’ that share a common mode of action and chemical structure. The Mode of Action Group (A, B, etc.) refers to the biochemical process inhibited by the fungicide, such as cell wall synthesis, respiration, etc. Sub-groups (A1, A2, etc.) within a Mode of Action Group refer to specific biochemical […]

Introduction to Insecticide Resistance
Insecticides are organized into classes—organophosphates, carbamates, pyrethroids, neonicotinoids, etc.— that share a common chemical structure and mode of action (MOA). MOA is the specific process by which an insecticide kills an insect, or inhibits its growth. The target site of action is the exact location of inhibition, such as interfering with the activity of an enzyme […]
