2012和2013年连续两年在野外对苍耳柄锈菌三裂叶豚草专化型的寄主专一性进行了评价。结果表明,供试的82种植物中,小麦和菜豆发生了锈病;野外三裂叶豚草锈病发生地周围的农作物和野生植物中,向日葵、反枝苋和大籽蒿3种植物发生锈病,但只有三裂叶豚草锈病的病原菌为苍耳柄锈菌三裂叶豚草专化型,说明苍耳柄锈菌三裂叶豚草专化型寄主专一性强,可用于三裂叶豚草的防控。
In 2012 and 2013, the specificity of host-specific species of the three-legged ragweed ragweed was evaluated in the field for two consecutive years. The results showed that the rust of wheat and bean was found in the 82 plants tested. Among the crops and wild plants around the occurrence site of the rust of Crassulacasa trifoliata, rust occurred in 3 species of plants including sunflower, Amaranthus retroflexus and Artemisia major, However, only the pathogen of Crassula australis was Corymbosea gossypii, which showed that the herbivore of Tricholoma grossedentata was specific and could be used for three-leaf Ragweed prevention and control.
