Summary: This study evaluated the allelopathic effects of essential oils from six different plant species on seed germination and seedling growth of barley and wheat. All six essential oils exhibited an allelopathic effect on both plants, with different concentrations showing varying levels of suppression. The study's results can be utilized in developing commercial products for controlling pre-harvest sprouting of wheat and barley, with further research needed to verify the results under field 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 presents a green downstream process for obtaining and evaluating phenolic compounds from cowpea seeds and pods, with higher antioxidant activity and bioactivity observed in pod extracts compared to seed extracts. The results suggest that cowpea phenolic extracts have high potential as nutraceutical and functional ingredients in food formulations, providing added-value benefits to the cultivation of this legume.

Summary: Increased antibiotic resistance is a global health issue. Klebsiella pneumoniae (Kp), a top-priority microorganism, has strains that produce carbapenemases. Essential oils (EOs) can act as adjuvants and enhance antibiotic activity. The study demonstrates the potential of EOs in designing synergistic therapies with antibiotics to combat Kp infections.

Summary: Plant-based products such as essential oils and extracts have been widely used and produced in large quantities, potentially reaching the environment. Recent research has focused on the toxic effects of these products on non-target organisms, particularly in aquatic environments. While some products showed no toxicity or only at high concentrations, others were found to be toxic at very low levels, emphasizing the need for further standardized research in this area.

Summary: By 2030, the European Commission aims to cut chemical pesticide use and risks in half. Essential oils (EOs) have been studied as potential substitutes for nematicides, which are chemical agents used to control parasitic roundworms in agriculture. However, there is still a lack of information on which EOs have been used on different nematodes and how they have been applied. This study provides an overview of available reports and data, exploring the extent of EO testing on nematodes and identifying the most commonly used EOs and formulations.

Summary: Plant essential oils, such as those extracted from Mentha longifolia and Erigeron bonariensis, have shown potential as mosquito repellents and larvicides against Aedes aegypti mosquitoes. These oils can effectively control both larvae and adult mosquitos, making them a cost-effective and environmentally friendly alternative to synthetic repellents.

Summary: This study examined the effectiveness of five plant essential oils (PEOs) in controlling Tuta absoluta and their impact on the predator Nesidiocoris tenuis. The PEOs from Achillea millefolium and Allium sativum significantly reduced the infestation by T. absoluta and did not affect the reproduction of N. tenuis. In addition, the spraying of A. millefolium and A. sativum triggered the release of herbivory-induced plant volatiles, which can act as messengers in tritrophic interactions.

Summary: Plant extracts and essential oils possess a variety of molecules that have potential applications in medicine, the food industry, and cosmetics. Furthermore, these plant derivatives show promising activity in antitumor, antifungal, anti-inflammatory, and bactericidal effects. Different methodologies are needed to optimize the extraction, purification, and characterization of these biomolecules. Moreover, these plant products can be used in the synthesis of nanomaterials to reduce the harmful effects of conventional synthesis routes and combine the properties of nanomaterials with those present in extracts and essential oils.
