It is necessary for the government to prepare and propose methods to cope with important plant diseases. Meloidogyne incognita is an economically highly important plant parasitic nematode, which is widely distributed all over the world and has a wide range of hosts, covering important economic crops in my country. In addition, the impact of climate change on the pathogenicity, host range and other biological characteristics of the nematode is not yet clear. Therefore, it is extremely necessary to conduct related research based on prediction models of the future development of climate change, to assess the possible population dynamic changes of Meloidogyne incognita in the future, and develop related disease management stretegies. This research project aims to study the impact of climate changes on the nematode`s pathogenicity and population growth, and  further test the effect, applicability, and compatibility with other control methods of the potenial control materials. The outcome of this research will be useful information on Meloidogyne incognita management, which will assist realted goverment agencies to deal with the nematode problem immediately and effectively when needed.根瘤線蟲;氣候變遷;病原性;病害防治;Root knot nematode;Climate change; Pathogenicity;Disease management
