摘　　要：连续 4年对烟草脉斑病 (马铃薯Y病毒的发生规律及 4种药剂的防效进行了研究。结果表明 :该病在豫西烟区的初发期为 6月上旬 ,6月下旬～ 7月上旬进入盛发期 ;发病与气候、移栽期、施肥、蚜虫等因素关系密切。 4种药剂防效中 ,“金叶宝”2 0 0倍液药剂防效较好 ,其防效率达到 71.4 7%。Occurrence regularity and control effect of PVY with 4 chemicals were studied in four successive years. The results showed that early occurrence stage of the diseases at tobacco growing areas in west Henan was in the first ten\|day period of June, and full occurrence stage was from the last ten\|day period of June to the first ten\|day period of July; the occurrence of the disease was closely related to climate, transplanting time, fertilization, and Myzus persicae (Sulzer) etc.; and the control effect of Jinyebao in one 200th dilution among the 4 chemicals was the best and reached 71.47%.
