节水技术我国是一个严重缺水的国家,节水技术的推广已成为当前农业可持续发展的重要措施之一。在世界一些发展中国家,滴灌技术广泛使用,效果显著,相信不久的将来,这项技术将在我国广泛采用。但滴灌技术的采用,将带来一些病虫害发生变化。如长期以来,我国农民习惯于大水漫灌,一些高湿度条件下易发病害,如灰霉病和霜霉病发生频繁。随着滴灌技术的推广,高温、低温条件下易发生病害如白粉病将难以防除。由于白粉菌种类繁多,各种白粉菌对不同脱甲基抑制剂(DMI)的耐受性不同,而且对多种DMI存在交互抗
Water-saving technology China is a country with severe water shortage. The promotion of water-saving technologies has become one of the important measures for the sustainable development of agriculture. In some developing countries in the world, drip irrigation technology is widely used and has achieved remarkable results. It is believed that this technology will be widely adopted in our country in the near future. However, the introduction of drip irrigation technology will bring some changes in pests and diseases. For a long time, peasants in our country are accustomed to flood irrigation and some plants are prone to diseases under high humidity, such as gray mold and downy mildew. With the promotion of drip irrigation technology, diseases such as powdery mildew that are prone to occur under high temperature and low temperature will be hard to control. Due to the wide variety of powdery mildew strains, various powdery mildew strains are different in tolerance to different demethylation inhibitors (DMIs) and have cross-resistance to various DMIs
