The plant growth regulator active ingredient and the bactericide active ingredient have a mass ratio of 1:1-10:1-20.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The inorganic salt is sulfate, chlorate or nitrate of iron, manganese, zinc, or of copper, molybdate, or borate. The sulfate of iron is ferrous sulfate. The molybdate is ammonium molybdate. The borate is sodium borate.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The photosynthesis promoter active ingredient comprises cyclodextrin, titanium ascorbate, or titanium citrate. ACTIVITY - Insecticide; Fertilizer; Plant Growth Regulant; Antibacterial.    ADMINISTRATION - The insecticidal fertilizer is applied by diluting each gram of the insecticidal fertilizer with 0.7-2 kg of water and uniformly mixing to obtain insecticidal fertilizer preparation; and using the preparation at period from boot stage to pustulation stage of crop by spraying 15-50 g of preparation/667 m2 of crop. If the crop is paddy, the preparation is applied twice on early earring stage and full heading stage. If the crop is wheat, the preparation is applied once on the early pustulation stage of the wheat. If the crop is corn or Sorghum, the preparation is applied once on the tasseling stage of corn or Sorghum. The insecticidal fertilizer preparation is uniformly sprayed when there is no dew on the leaf of the crop. (all claimed)
