Echinochloa spp. are among the most difficult to control in paddy weeds because of the development of resistance to a wide range of herbicide classes. One of the aims of EpiResistenze project is to map the evolution of Echinochloa spp. HeR in the Lombardy rice territory, analyzing HeR gene expression and focusing on the ecological (biotic and abiotic) factors related with HeR developement. The mapping of HeR populations was performed during the 2019 summer season. The resistant Echinochloa populations were georeferenced using Q-GIS3 software, and relative maps were produced. Preliminary results show that Echinochloa spp. HeR populations are widely spread throughout the rice-growing area of the provinces of Pavia, Milan, Lodi and Mantua, including areas where no resistance has been detected until now.

Abstract
Echinochloa spp. are among the most difficult to control in paddy weeds because of the development of resistance to a wide range of herbicide classes. One of the aims of EpiResistenze project is to map the evolution of Echinochloa spp. HeR in the Lombardy rice territory, analyzing HeR gene expression and focusing on the ecological (biotic and abiotic) factors related with HeR developement. The mapping of HeR populations was performed during the 2019 summer season. The resistant Echinochloa populations were georeferenced using Q-GIS3 software, and relative maps were produced. Preliminary results show that Echinochloa spp. HeR populations are widely spread throughout the rice-growing area of the provinces of Pavia, Milan, Lodi and Mantua, including areas where no resistance has been detected until now.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
