Chiral isomeric
sulfite compounds, and preparative separation and application of chiral structures thereof are disclosed,. which belong to the technical field of
agriculture. The present disclosure has found that the chiral isomeric
sulfite compounds having the structure of general formula (A) have excellent inhibitory activities against pest eggs, especially have strong inhibitory activities against eggs of thrips, mites, Lepidoptera moths, Aleyrodidae and
Harmonia axyridis, and meanwhile have germicidal activity, and their
absolute configuration are obtained through preparative separation. The compounds with such structures can be used for killing pest eggs and germs, and have high research value of
agrochemical, having broad application prospects in the field of agricultural
pharmacy. 20 25 20 23 00 31 M ar 2 02 5 2 0 2 5 2 0 2 3 0 0 3 1 M a r 2 0 2 5
