A recent study released by Nomisma a leading European Economic Research Institute confirmed that the economic impacts of weed management systems in rice are significant. It highlights changes in rice weeding’s practices, over ten-years period in Italy following appearance of populations resistant to herbicides which made the weed management in rice more difficult. In case of rice, this phenomenon is more critical than in other crops. The higher intensity of weed infestations, the shift in the floristic composition, and the progressive diffusion of populations resistant to herbicides have led to a higher competition between weeds and the rice crop, heavily impacting its productivity and quality.
When talking to rice growers in some leading countries in Europe like Italy, Spain and Turkey (more than 300 growers interviewed) the key challenges for Rice production are very consistent across geographies: Lack of profitability, weed management and environmental regulation or pressure are main challenges in all countries. Here below the summary of their feedback.
