摘　　要：对大方县辣椒细菌性叶斑病田间发生规律进行了调查和药效筛选试验。结果表明:辣椒细菌性叶斑病在苗床阶段就开始发生,一般4月下旬开始发病,6月份病情增长较快,6月下旬达发病高峰,7月份后老病叶大量掉落,新病叶增加缓慢,病情不再发展;发病初期用72%农用链霉素可溶性粉剂、77%可杀得可湿性粉剂或25%唯它灵可溶性粉剂连续防治2次,可取得较好防效。The occurrence regularity of bacterial leaf spot on hot pepper and its field trials of pesticide were investigated and studied in Dafang county. The result shows that the disease appears in the end of April and an increasing damage in June. The peak period of the disease is the end of June. Abundantly diseased leaves fall off in July, hence a few leaves infected. A good controlling effect could achieve by continuously treating with 72% agricultural streptomycin soluble powder, 77% Copperhydroxide wettable powder or 25% streptomycin sulfate soluble powder for two times at early stage of the disease.
