摘要
1996～1998年对常德、沅江及本校农场的温洲蜜柑、建柑、酸橙、甜橙、金香柚的白癞病病果进行分离、接种和再分离,证实柑桔白癞病病原为:柑桔炭疽刺盘孢菌Colletotrichum gloeosporioides Penz.;柑桔蒂腐菌Botryodiplodia theobromae Pat.(原名Diplo-dia natalensis Pole- Evans);柑桔黑腐交链饱霉 Alternaria citri EII.et Pierce。3种病原真菌可以单独或混合侵染。
Citrus white scaled lesion, a disease of the skin of citrus fruit, whose symptoms are white scales in various forms,causes necroses of epidermic cells. Experiments in the past two years have proved three fungi to be the pathogens- Colletotrichum gloeosporioides Penz, Botryo-diplodia theoboromae Pat. and Altemaria citri Ell.et Pierce.They may infect citrus fruits singly or jointly.
