Research progress on alfalfa Verticillium wilt caused by Verticillium alfalfa
Alfalfa(Medicago sativa L.)is the most important pasture crop in China in terms of its planting area and status in animal husbandry.Verticillium wilt is a devastating disease worldwide,and China has listed it as an import plant quarantine object.The causal agent was previously known as Verticillium albo-atrum and renamed Verticillium alfalfae in 2011.However,on the list of quarantine diseases for the plants imported to China,the causal organism of alfalfa Verticillium wilt was still designated as V.albo-atrum.This undoubtedly brings much confusion to the quarantine work.In China,the disease was ever found in Zhangye City,Gansu Province,in 2016,and has now been widely distributed in the Hexi Corridor,the most important commercial alfalfa produc-tion area in China.It is vital to encourage relevant researchers to pay more attention to this dangerous disease so as to strengthen integrated control measures of the disease.This paper reviews research progress on Verticillium wilt of alfalfa,including the causal pathogen species,distribution,infection cycle and management measures,and suggests future research directions.
