Topological indexes of A , B , C and D were all obtained from the different combination of topological vertex degree. A QSAR equation for this series of compounds was established based on the multi-linear regression method and a new group of autocorrelation topological indexes. The results showed that the biological activity is linearly correlated with the volume and branching size of the quinclorac derivatives. Finally, new herbicide was designed based on all QSAR results.

Preliminary bioassays indicated that many title compounds exhibited excellent fungicidal, or insecticidal and acaricidal activities. The strobilurin derivatives containing substituted pyrimide ring have lower biological activity than the strobilurin derivatives containing substituted pyrazole ring which exhibited good fungicidal activity against RB (0.92 mg/L), TLB (0.3 mg/L), CDM (12.5 mg/L) and WPM (1.56 mg/L).
