Summary: The study found that planting winter cover crops such as cereal rye, common vetch, black oat, and feral radish can effectively suppress Italian ryegrass infestations and reduce the soil seed bank. Compared to weedy fallow, these crop management practices can reduce infestations by up to 80% to 96%.

Summary: This study assesses the impact of alien species on rice field cultivations in the Western Po Plain. The results show a decrease in biodiversity and an increase in short-lived and alien species. Organic farms have higher biodiversity levels but also a higher percentage of invasive alien species. The deterioration of the territorial-landscape context plays a major role in shaping these patterns.

Summary: Undersown cover crops in combination with bio-preparations play an important role in weed control and seed yield of spring oilseed rape in organic farming. Among the cover crops, hairy vetch showed rapid growth and significantly higher aboveground dry biomass compared to other crops, while crimson clover had significantly higher aboveground dry biomass than perennial ryegrass and winter rye. The cover crops did not suppress early emerging weeds, but bio-preparation-treated perennial ryegrass was the most effective in weed suppression. The highest oilseed rape seed yield was obtained in plots without any cover crops but with bio-preparations, while perennial ryegrass as a cover crop with bio-preparations resulted in the highest reduction in oilseed rape seed yield.

Summary: Cover crops can provide environmental benefits in spring-grain systems by diversification, reduced nitrate leaching, and carbon sequestration. Field trials showed no significant reduction in grain yield due to the use of cover crops. However, a literature synthesis indicated a potential yield reduction with Italian ryegrass sown at the same time as the grain.

Summary: Weeds have a negative impact on the growth and profitability of organic vegetable crops. Weed management is a major challenge for organic vegetable growers due to limited control options. Anaerobic soil disinfestation (ASD) is a non-chemical pest management technique that creates oxygen-free conditions in the soil for a specific period. This study investigated the effectiveness of warm season cover crops as carbon sources for ASD and their role in weed management. The results showed that incorporating cover crops in non-aerated conditions provided better weed control and improved tomato plant growth and yield compared to other treatments. Warm season cover crops have the potential to be used as carbon sources for ASD in organic tomato production.

Summary: Maintaining good soil structural stability is crucial for agricultural sustainability. Incorporation of cereal straw and use of cover crops can improve soil structural stability, increasing soil organic carbon content. Root biomass is marginally greater when cover crops are included, suggesting their potential benefits for soil stability.

Summary: Cover crops (CCs) have the potential to suppress annual weeds within agronomic cropping systems in the United States. However, this potential may vary depending on the specific environmental and management factors of different geographic areas. A meta-analysis of studies conducted in the U.S. Southeast found that CCs had a negative effect on weed density but no effect on weed biomass or cash crop yield. The key factor associated with weed density reduction was the biomass of the cover crops.

Summary: In this study, a series of fenoxaprop-P-ethylamino acid ester conjugates were designed and synthesized, and their biological activity and phloem mobility were tested. The results showed that these compounds exhibited better activity against barnyard grass and less phytotoxicity to rice. Compounds 3i, 3j, and 3k showed excellently herbicidal activities against barnyard grass and low phytotoxicity to rice.

Summary: Some Solanaceae plants, such as Solanum linnaeanum, contain sesquiterpenoid phytoalexins that can inhibit the germination and growth of target species. The leaf powder and aqueous extract of S. linnaeanum were found to be toxic to Lolium multiflorum, Sinapis alba, and Trifolium incarnatum. The effectiveness of the treatments varied depending on the matrix used, with L. multiflorum being the most sensitive and S. alba being the most resistant. The volatile chemical profile of S. linnaeanum leaves, characterized using SPME-GC/MS technique, revealed the presence of various compounds that could be useful in controlling harmful plants.

Summary: The present study chemically characterized the volatile composition of Citrus medica var. sarcodactylus fruit and evaluated the antiradical power, antibacterial activity, and cytotoxicity of its essential oil, hydrolate, and methanol extracts. The results showed that limonene and gamma-terpinene were the most abundant compounds in the fruit, and the essential oil exhibited good antiradical and antibacterial activities. The hydrolate did not show antibacterial activity, while the methanol extracts from both the exocarp and mesocarp had high efficacy against the tested bacteria. The extracts also showed cytotoxicity against leukemia cells.

Summary: In this study, the volatile content of three morphotypes of Achillea millefolium L. collected in different points of the Italian Alpine area was analyzed using SPME-GC-MS technique. The results showed a high content of terpenic compounds in all morphotypes, with a predominance of monoterpenes over sesquiterpenes except for the white morphotype at collection point A. Statistical analysis was also performed to interpret the distribution of the components in relation to the morphotype and collection point.

Summary: The chemical composition and biological activities of fresh leaves and inflorescences of Chinook hops were investigated. Forty-two molecules belonging to different chemical classes were identified, with twenty-three being terpene compounds. Activity assays were carried out on the powders after extraction with methanol and distilled water, and the methanolic extracts showed stronger antioxidant activity. Preliminary studies on human cancer cell lines also showed marginal effects on cell proliferation.

Summary: The chemical content of essential oils from four Pinaceae plants (Abies alba, Picea abies, Pinus cembra, and Pinus mugo) was analyzed using SPME-GC-MS technique. Monoterpenes, such as alpha-pinene, limonene, and beta-myrcene, were the most abundant compounds. The liquid phase of the essential oils was dominated by mono- and sesquiterpenes. The essential oils exhibited significant phytotoxic activity against Lolium multiflorum and Sinapis alba, reducing germination and growth rates.
