Since pea leaf weevils over winter as adults, seed treatments are your first line of defense. Research has shown 3 that seed treatment is much more effective in decreasing losses from pea leaf weevil than foliar treatment.

Seed treatments not only protect against foliar feeding but also protect nodulation on the roots and minimize inhibition of nitrogen fixation by the pea .
