Cereal rusts and powdery mildews are very important diseases occurred on the cereal crops, which caused yield losses at 5-10% in general and even more than 30% while severe epidemics occurred. In recent years, with the global climate change, change of cultivation system and evolution of the pathogens, the world is facing great challenges caused by cereal diseases.展开更多

Nearly 650 participants from more than eight countries (regions) and international organizations attended this conference. The conference provided an communication platform for international counterparts, and the content was closely related to all aspects of dairy cow health, including dairy mastitis pathogens, diagnose, therapeutics, management, residue, bacterial resistance and milk safety. Here we are pleased to have the opportunity to organize a special focus and provide the most updated knowledge of the given topics.展开更多
