1982—1985年对棉花黄萎病菌 Verticillium dahliae 在8科31种栽培植物及31科87种杂草中的寄主范围进行了鉴定试验。查明在31种栽培植物中5种高度感病,8种表现中度或轻微症状,此13种为寄主。水稻未表现症状但分离到病原菌,回接棉花具有致病力。31种中非寄主12种,还有5种须重复鉴定。在87种杂草中,肯定的寄主48种,可疑寄主6种,无症状带菌体5种,非寄主23种,其余5种未定。本项研究首次查明禾本科植物水稻及野燕麦为Verticillium dahliae 的无症状带菌体。 The host range of Verticillium dahliae from 1982 to 1985 was tested in 31 cultivated plants of 8 families and 87 weeds in 31 families. Five of the 31 cultivated plants were identified as being highly susceptible, eight exhibiting moderate or mild symptoms, and the 13 being host. Rice did not show symptoms but the pathogen isolated, back to cotton with pathogenicity. 31 kinds of host 12 kinds of Central African host, there are 5 species to be repeated identification. Of the 87 weeds, 48 ​​were positive, 6 were suspicious, 5 were asymptomatic, 23 were non-host, and the remaining 5 were undetermined. This study, for the first time, identified asymptomatic bands of gramineous plants, rice and wild oat, Verticillium dahliae.
