Pests and Diseases
The tree has a high resistance to the fungus Ophiostoma himal-ulmi endemic to the Himalaya and the cause of Dutch elm disease there. However, U. wallichiana was found to be one of the most preferred elms for feeding and reproduction by the adult elm leaf beetle Xanthogaleruca luteola and feeding by the Japanese Beetle Popillia japonica in the USA. Tests in Italy confirmed the American findings, and also determined a moderately high susceptibility to Elm Yellows, meanwhile in the Netherlands the species was also found to be susceptible to coral spot fungus Nectria cinnabarina.
