- 1. WELCOME DEPARTMENT OF ENTOMOLOGY, COLLEGE OF AGRICULTURE, PJTSAU ,HYDERABAD CLASSIFICATION OF INSECTICIDES AND THEIR MODE OF ACTION N.RAMYA SRI RAD/ 2017-12
- 2. PURPOSE • The IRAC Mode of Action (MoA) classification provides growers, advisors, extension staff, consultants and crop protection professionals with a guide to the selection of acaricides or insecticides for use in an effective and sustainable acaricide or insecticide resistance management (IRM) strategy. • Rules for inclusion of a compound in the MoA list • Names To be included in the active list, compounds must have, or be very close to having, a minimum of one registered use in at least one country. • when more than one active ingredient in that chemical sub- group is registered for use, the chemical sub-group name is used. • when only one active ingredient is registered for use, the name of that exemplifying active ingredient may be use CLASSIFICATION OF INSECTICIDES AND THEIR MODE OF ACTION
