| Abstract: | Chemical additives have been used to enhance the activity of Bt against Plutella xylostella. Chemicals of various groups were assessed with respect to their effect in increasing the activity of fermentative liquid of Bt. Using leaf-dip bioassay, preliminary screened 46 chemical additives. The result indicated that 30 additives, including 11 alkaline compounds, 3 acidic compounds, 8 inorganic salts, 3 aromatic compounds, 5 protein solubilizing agents, were able to increase the efficacy of Bt at 1% concentration. Among the 30 compounds boric acid and potassium carbonate were better to increase the activity of Bt. |
