During using anaerobic fermentation slurry as insecticide, there had many problems that are random using, non-strictly prevention and curing time, non-suitable temperature and consistency mixture ratio ctc. In this research, fristly the different mixtures are made according to the different ratio of slurry to additive. Then the insecticidal effects of the mixture are tested in different conditions so as to find the good matches of slurry and additive in laboratory. According to the up result of the good matches extents of mixture, the field experiment is made to test the mixture's insecticidal chraricter and is further found new dosage form which has many good indexes such as good insecticidal effectiveness, little additive dosis ctc. So as to looking for the dosage form's synergism, the significant analysis is done and the characters of the dosages are tested which are ecological and environmental and the new types of dosage are determined. At last, for proving the dosage's field insecticidal potency, the wide field area experiments are done and four new style dosages are triturated which adapt ecological agriculture development. Aadditionally the effective period of the mixtures are tested when other experiments are done.
