Synthesis and Insecticidal Activity of Novel Pyridine Methanesulfonates

A model has been developed which has led to the design and synthesis of novel 6‐methanesulfonyloxypyridine‐2‐carboxamides with insecticidal activity, low mammalian toxicity and safety to aquatic organisms. The amides formed from amines with α branching (e.g. isopropyl and sec‐butyl) demonstrated the highest level of activity. Rice nursery box field test results on laboratory raised insects gave insufficient control of the entire Japanese hopper spectrum to warrant further development of these compounds. © 1997 SCI
