BACKGROUND As regulations on pesticides become more stringent, it is likely that there will be interest in steam as an alternative approach for soil disinfestation. This study investigates the feasibility of utilizing a soil steaming device for thermal control of invasive plants. RESULTS Seeds of Echinochloa crus-galli, Impatiens glandulifera, Solidago canadensis, and rhizome fragments of Reynoutria × bohemica were examined for thermal sensitivity through two exposure methods: (1) steam treatment of propagative material in soil; (2) exposure of propagative material to warm soil just after heated by steam. Soil temperatures in the range of 60–99 °C and dwelling period of 3 min were tested. Increased soil temperature decreased seed germination/rhizome sprouting. The exposure method had a significant effect where higher temperatures were needed to reduce the seed germination/rhizome sprouting in method 2 explained by the effect of extra heat given in method 1. Using method 1, for E. crus-galli and S. canadensis, the maximum mean temperature of approximately 80 °C was enough to achieve the effective weed control level (90%). This was lower for I. glandulifera and higher for R. × bohemica. Using method 2, 90% control was achieved at 95 °C for S. canadensis; more than 115 °C for I. glandulifera; and more than 130 °C for E. crus-galli and R. × bohemica. CONCLUSION Our findings showed a promising mortality rate for weeds propagative materials through soil steaming. However, the species showed varying responses to heat and therefore steam regulation should be based on the differences in weeds' susceptibility to heat.

The purpose of the experiment was to investigate whether the Potato Cyst Nematode (PCN) will survive steam treatment in SoilSaver. The results from the SoilSaver experiments show that heat treatment with steam affects PCN’s ability to hatch from the eggs. Juveniles who did hatch, died shortly after. No larvae or eggs that survived the treatment were found in any of the replications.

Abstract
The EU’s Farm to Fork strategy aims to create fair, healthy, and environmentally friendly food systems, ensuring universal access to sufficient, safe, nutritious, and sustainable food. Increasing the production and consumption of organic food is considered crucial to achieving these objectives. This study explores the development of organic food in four selected Nordic countries: Denmark, Finland, Norway, and Sweden. We have observed the variance in the market share of organic products in the retail sector among these countries, with 13, 2.5, 1.73 and 8.9%, respectively (2021 statistics). This highlights a significant gap, with Denmark and Sweden leading in organic food consumption. We seek to understand the reasons behind this disparity by delving into public policies governing organic food strategies in the selected countries. The analysis entails examining multiple policy documents to pinpoint fundamental strategies and significant milestones influencing the development of the organic sector. Our findings indicate that Denmark and Sweden have historically implemented supportive policies, including financial incentives, subsidies, and regulatory frameworks, to promote organic agriculture. Their consistent, credible, comprehensive and coherent governmental policies and long-term commitments offer a stable environment for the organic sector to flourish. They seem to possess extensive distribution networks and better market access for organic products, contributing to the sector’s growth. The accessibility and availability of organic products in retail outlets play a vital role in influencing consumer choices. The paper provides policymakers with valuable insights into how to foster the consumption and production of organic food, not only within the case studies but also in other national contexts.
