Mode of Action & Effects

• It interferes with chitin synthesis, preventing insects (especially larval stage) from forming proper exoskeletons (cuticle). 

• It also has ovicidal activity—i.e. affects eggs, reducing hatching success.

• Its action is more developmental / growth-disrupting rather than quick “knock-down.”
