疫霉属是植物致病菌,它是导致1840年爱尔兰马铃薯大饥荒的罪魁祸首之一。疫霉属真菌的一些种浸染数千种不同植物,因此它们浸染几乎所有观赏植物,从绿化树种到小型室内花卉。一些疫霉属真菌的小种对某种特效的真菌有抗性。弗罗里达州立大学的Ali说,“我们发现一些疫霉属小种对某种特效的真菌有抗性,但所幸的是,它们至少受到另一种杀真菌剂的控制。”因此,在种植业中交替使用不同种类的杀真菌剂是非常重要的。
Phytophthora, a plant pathogen, is one of the culprits that led to the 1840 potato famine in Ireland. Some species of Phytophthora penetrate thousands of different plants, so they dip almost any ornamental plant, from tree species to small indoor flowers. Some species of Phytophthora are resistant to a specific fungus. Ali of Florida State University states, “We found that some species of Phytophthora are resistant to a specific fungus, but fortunately, they are at least under the control of another fungicide.” "Therefore It is important to use different types of fungicides alternately in the farming industry.
