If you are holding an M.Sc. degree in Chemistry, you are generally considered educationally eligible for holding and renewing a pesticide licence under the Insecticides Act, 1968. In most states, candidates with a relevant postgraduate degree such as M.Sc. Chemistry are not required to undergo mandatory short-term training (such as a 15-day training program) for licence renewal, as long as they already possess a valid licence and meet the prescribed qualification criteria. However, the exact requirement can vary slightly from state to state, as licence renewal is handled by the State Agriculture or Licensing Authority. Some states may ask for refresher training only if there has been a long gap, licence lapse, or change in rules. Therefore, it is advisable to check with your respective State Agriculture Department or the licensing authority where your licence is registered to confirm whether any training is required in your specific case. In most cases, degree holders like you can renew the licence by submitting the renewal application, academic certificates, and prescribed fee without additional training.
