Nonglangzhong 8% ME is a microemulsion (ME) formulation containing two active ingredients:

1. Chlorfenapyr (5%) – A broad-spectrum insecticide/acaricide that acts as a pro-insecticide. Once ingested or absorbed by pests, it disrupts mitochondrial function, leading to paralysis and death.
2. Lufenuron (3%) – An insect growth regulator (IGR) that inhibits chitin synthesis, preventing insect larvae from molting and maturing into adults.
