植物病原真菌普遍存在于环境中,2万种不同的真菌物种需寄生在植物宿主上以延续它们的生命周期。受真菌侵染的植物宿主释放出无以数计的真菌孢子,其营养同时也被孢子带走。在美国,杀菌剂一般用于广袤的果园和菜园来保护其免受真菌侵染。如果美国继续大规模生产水果和蔬菜,杀菌剂是至关重要的。除了可从最近试验数据、种植者实 Plant pathogenic fungi are prevalent in the environment and 20,000 different fungal species are parasitic on plant hosts to extend their life cycle. The fungal-infested plant host releases innumerable fungal spores whose nutrients are also taken away by the spores. In the United States, fungicides are commonly used in vast orchards and vegetable gardens to protect them from fungal infections. Bactericides are crucial if the United States continues mass production of fruits and vegetables. In addition to the recent experimental data, growers are real
