1984年8月,在佛罗里达中部的苗木场里发现了柑桔溃疡病(Xanthomonas campestris pv.citri),这是该病自1933年被消灭以来在佛州的第一次报道。为防止溃疡病菌在柑桔果实上的扩散,本文评价了二价季铵化合物(n一烷基二甲基(艹卡)苄基氯化铵、n一烷基二甲基苄基乙基氯化铵)、氯、二氧化氯、SOPP(邻苯酚钠)、过醋酸(35％)等几种表面消毒剂对柑桔果实表面溃疡病菌(一个X.c.pv.vesicatoria株系和二个佛州X.c.pv.citri株系)的消毒效果。结果如下。 1.管内试验比较 三个病原菌株系对各种消毒剂反应相似。1微克/毫升氯或二氧化氯及Alcide混合物(1份次氯酸钠∶80
In August 1984, Xanthomonas campestris pv. Citri was found in seedling farms in central Florida, the first report in Florida since its eradication in 1933. In order to prevent the spread of canker bacteria on citrus fruits, bivalent quaternary ammonium compounds (n-alkyldimethylbenzyl ammonium chloride, n-alkyldimethylbenzyl chloride Ammonium chloride, chlorine dioxide, chlorine dioxide, SOPP (sodium ortho-phenolate), peracetic acid (35%) and other surface disinfectants on citrus fruit surface canker pathogen (one Xcpv.vesicatoria strains and two Florida Xc pv.citri strain) disinfection. The result is as follows. 1. In-tube trials comparing the three pathogenic strains reacted similarly to various disinfectants. 1 μg / ml chlorine or chlorine dioxide and Alcide mixture (1 part sodium hypochlorite: 80)
