英文摘要： The emergence of increase heavy lost of bacterial diseases has posed a serious concern for pesticide professionals during the last decade, the application of most traditional pesticides has not proved very effective. As our ongoing search for novel sulfone compounds possessing antibacterial properties, on the basis of the acylamide fungcides lead compounds, design, synthesis, antibacterial activity, qualitative and quantitative SAR of novel sulfone derivatives containing heterocyclic(thiadiazole, oxadiazole) acylamide will be carried out. Spacial attention would be paid to bacterial leaf blight of rice, bacterial leaf streak of rice, tobacco bacterial wilt and bacterial wilt of solanaceae.Possible mechanism of high activity compound agains bacterial would be developed. Some high active, safe, easy to use, lower cost compounds are expected to be found. In a word, two lead compounds with high activity and one title compounds with potential field application would be developed.
