Bufluranate is a non-systemic acaricide, which mainly acts by contact killing, can control eggs, nymphates and adult mites, and the mechanism of action is to inhibit mitochondrial protein complex II, hinder electron (hydrogen) transport, and disrupt phosphorylation reactions. Biphenylhydrazine ester is not systemic, but it has a contact killing effect, inhibits aminobutyric acid (GABA) receptors in the central nervous system of mites, and is effective against all life stages of mites. The mixture of the two can be used to control citrus tree spider mites (resistant to pest mites on various crops).
