water dispersible granules,
wettable powder, micro-
capsule suspending agent, missible oil,
emulsion in water or
microemulsion or other dosage forms. The insecticidal composition has reasonable components, good insecticidal effect and low
medication cost; in addition, the activity and the insecticidal effect of the insecticidal composition are not simple overlaying of the activities of various components; and compared with the traditional single preparation, the insecticidal composition has the advantages of remarkable insecticidal effect and synergistic effect, capability of retarding generation of resistance, less preparation residues, no
pollution to crops, good safety, accordance with safety requirements of
pesticide preparations and better control effects on rice steam borers, vegetable
