摘　　要：烟草气候斑病的发生与气象、品种及栽培条件有密切的关系。低温多雨雷电交加的天气比一般天气病害重，国外引进品种比我国新育成品种病害重，Ｋ３２６ 比ＮＣ８９、中烟９０ 病害重，水田烟比旱地烟病害重，施钾少氮钾比失调比施钾多氮钾比协调病害重，已感染黄瓜花叶病毒和早花的烟株比健壮烟株病害重。在供试１８ 种药剂中，以代森锌的防治效果最好。所组装的综合防治措施已初步推广应用。The occurrence and control of tobacco weather fleck were studied from Guangxi from 1993 to 1996.The results showed that low temperature,heavy rainfall and lightning storm were the main factors causing this disease.Resistance of various varieties to the disease was varied remarkablely.The plants grown in paddy and offered low levels of potassium or disproportion of nitrogen and potassium were more serious than that in nonirrigated land and high levels of potassium or coordination of them.It was more in CMV infected or early blossoming plants than in normal plants.Among 18 tested chemicals,zineb was achieved the best result.Zineb and combined control measures were recommended and applied in practice.
