Summary: Many studies have shown that certain essential oils have herbicidal effects and can be used as alternatives to chemical herbicides. In this study, the chemical composition of essential oils from two ecotypes of O. heracleoticum in Southern Italy was compared and their potential as natural herbicides was investigated using seeds of Raphanus sativus, Sinapis arvensis, and Lolium multiflorum. The study also evaluated the inhibitory activity of the essential oils on the alpha-amylase enzyme, which is involved in seed germination. The results showed that the essential oils exhibited herbicidal and alpha-amylase inhibitory activities, suggesting their potential for further exploration.

Summary: Essential oils can be a valuable source of new food-safe and healthy nematicidal products due to their strong activity on crop pathogens and pests, as well as their low environmental persistence. Testing 16 different essential oils from various botanical origins and compositions revealed that most of them are highly suitable for formulating new safe nematicides.

Summary: Soil-borne phytopathogens can cause significant losses to cereal and horticultural crops worldwide. Synthetic pesticides are still widely used, but the search for sustainable alternatives is becoming more urgent. The incorporation of botanicals and aromatic plants into agricultural practices can help control plant diseases, but their application needs to be carefully regulated to avoid negative impacts on soil fertility. This study reviews the efficiency of secondary metabolites from aromatic and medicinal plants as biopesticides against soil-borne plant pathogens, and highlights the potential of recycling waste from aromatic plant industries to improve soil health.

Summary: This study aimed to assess the post-harvest impact of UV-C irradiation on the metabolic profile of essential oils (EOs) from fresh leaves of Piper aduncum cultivated in Southeastern Brazil. The results showed that UV-C radiation can alter the relative percentage of specific chemical constituents, with a significant increase in the relative percentage of the compound dillapiole. This study suggests that UV-C irradiation may be a promising technique for enriching the dillapiole content in the essential oil of P. aduncum.

Summary: This study developed biopolymer-based films with improved properties by adding essential oils such as lemon, orange, grapefruit, cinnamon, clove, chamomile, ginger, eucalyptus or mint. Lemon essential oil prevented mass reduction but degraded the microstructure and elasticity. Mint and ginger essential oils resulted in films with a more homogenous microstructure, but higher concentrations led to pore appearance and color modifications.

Summary: This study aimed to identify plant-based natural pesticides to control Tribolium castaneum and Aspergillus flavus in stored grains. Essential oils from Chenopodium ambrosioides and Erigeron canadensis showed excellent toxicity against T. castaneum and exhibited good anti-fungal activity against A. flavus. These findings suggest that these essential oils can play an important role in protecting stored grains from contamination by T. castaneum and A. flavus.

Summary: The study found that the suicide rate in Uganda has significantly increased since the onset of the COVID-19 pandemic. The annual incidence rates of suicide attempts and completed suicides were approximately 60 per 100,000 people and 3 per 100,000 people, respectively. The number of suicide attempts rose following the first month of COVID-19 lockdown, with poisoning being the most common method. This study highlights the urgent need for proactive interventions, such as controlling pesticides and herbicides, to prevent suicide in the community, especially during pandemic conditions.

Summary: Repellents made with essential oils are effective in protecting people from outdoor mosquitoes. The study found that Perovskia atriplicifolia, Citrus reticulata (fruit peels), C. reticulata (leaves), Mentha longifolia, and Dysphania ambrosioides were the most effective essential oils in repelling Aedes aegypti mosquitoes. P. atriplicifolia showed the longest repellent effect, followed by C. reticulata (peels), M. longifolia, and C. reticulata (leaves). The study also identified the major constituents of these essential oils. The results could contribute to the development of plant-based commercial repellents for dengue mosquitoes.

Summary: This study evaluated the potential of Tagetes minuta essential oil (EO) to inhibit biofilm and related virulence factors. The EO significantly inhibited virulence factors linked with quorum sensing (QS), such as pyocyanin production, protease production, and swarming motility. It also inhibited biofilm formation, indicating that the inhibition of biofilm by EO is through the inhibition of the QS pathway. However, the EO showed limited antibacterial activity. The study confirmed that the EO interferes with the QS pathway that controls various virulence factors.

Summary: This study explores the barriers and facilitators to the utilization of community drug distribution points (CDDPs) among people living with HIV (PLHIV) in south-western Uganda. The results show that peer support, positive attitudes from primary healthcare providers, satisfaction with HIV services, and accessibility of anti-retroviral medication services are major facilitators for CDDP utilization. Stigma, lack of physical infrastructure, and lack of comprehensive services are identified as the main barriers. The study suggests improving physical infrastructure at CDDP sites, protecting the privacy and confidentiality of PLHIV, and addressing stigma through interventions from primary healthcare providers and other stakeholders.
