“…Many plants are reported to increase the level of antioxidants, both enzymatic and non-enzymatic, in response to biotic or abiotic environmental stresses [64,66]. Allelochemicals can cause oxidative damage in target plants and induce so-called allelopathic stress by producing a high amount of ROS during response to environmental stresses, as evidenced by the enhanced activity of ROS-scavenging enzymes and higher intensity of lipid peroxidation [65,67].…”

The biological activity (contact and contact-digestive toxicity, repellent and fumigant effects, effect on the insect’s development and life cycle parameters) of industrial hemp (Cannabis sativa L.) ethanolic extract was assessed against Plodia interpunctella, the most destructive storage pest of sunflower. Additionally, the study aimed to examine the phytotoxic activity of the extract in order to assess its potential as a sunflower grain protectant. Phytotoxicity assessment was based on the effect on germination energy and seed germination and the activity of antioxidative enzymes, enzymes of the polyphenolic metabolism, and the intensity of lipid peroxidation in sunflower seedlings. The antioxidant capacity and content of phenolic compounds (total phenolics and total tannins) were also measured in seedlings. In the experiments, 70% ethanolic extract of dried flowering buds of industrial hemp (variety Helena) was applied at 0.5%, 1.0% and 2.0% concentrations directly on sunflower seeds. Ethanol solution (70%) was the control. The hemp extract (1% and 2%) revealed medium repellence for P. interpunctella larvae (L3–4) while at 2% concentration it caused 42.5% larval mortality after 72 h. Moreover, the insect’s development was prolonged and fecundity significantly reduced in hemp treatments. The extract did not exhibit fumigant activity. Germination energy and germination of sunflower seeds were stimulated in treatment with 2% hemp extract, while most biochemical parameters of the seedlings were not significantly affected by the hemp extract.

“…The applied protocol was based on transferring third-instar larvae of the fly in glass vials with filter papers impregnated with different dilutions of the essential oils [ 153 ]. Various residual or surface contact bioassays, with certain modifications in their protocols, were used to test the bioactivity of a variety of plant extracts and essential oils against eggs, larvae, and adult specimens of insects and mites [ 70 , 72 , 74 , 82 , 87 , 89 , 90 , 92 , 98 , 102 , 113 , 130 , 147 , 148 , 150 , 154 , 155 , 156 , 157 , 158 , 159 ]. For instance, Erdogan and Mustafa dipped tomato leaf discs into the test solutions instead of pipetting a volume onto their surface and then placed Tuta absoluta larvae on them [ 92 ].…”

The development and implementation of safe natural alternatives to synthetic pesticides are urgent needs that will provide ecological solutions for the control of plant diseases, bacteria, viruses, nematodes, pests, and weeds to ensure the economic stability of farmers and food security, as well as protection of the environment and human health. Unambiguously, production of botanical pesticides will allow for the sustainable and efficient use of natural resources and finally decrease the use of chemical inputs and burden. This is further underlined by the strict regulations on pesticide residues in agricultural products and is in harmony with the Farm to Fork strategy, which aims to reduce pesticide use by 50% by 2030. Thus, the present work aims to compile the scientific knowledge of the last 5 years (2017–February 2023) regarding the Mediterranean plants that present biopesticidal effects. The literature review revealed 40 families of Mediterranean plants with at least one species that have been investigated as potential biopesticides. However, only six families had the highest number of species, and they were reviewed comprehensively in this study. Following a systematic approach, the extraction methods, chemical composition, biopesticidal activity, and commonly used assays for evaluating the antimicrobial, pesticidal, repellant, and herbicidal activity of plant extracts, as well as the toxicological and safety aspects of biopesticide formulation, are discussed in detail. Finally, the aspects that have not yet been investigated or are under-investigated and future perspectives are highlighted.

A comprehensive understanding of allelopathy and resource availability mechanisms is critical for protecting rare and endangered species, biodiversity and ecosystems. We treated 20 major plant species with a gradient of three aqueous extracts of Dacrydium pierrei litter and irrigation/nutrients to compare the relative importance of allelopathy and resource availability on roots, stem growth and seed germination using bioassays. The results showed that the height, ground diameter and aboveground biomass of individuals increased more quickly in the early stage, and rate of increase tends to slow down in the later. The allelopathy was species specific (inhibitory, neutral or promotive), and the survival rate and growth rate of saplings changed significantly along a resource treatment gradient (P< 0.05), indicating that the native species diversity was reduced by lower or higher resource availability in natural forests. The effect of allelopathy on trees was relatively weak during the treatments, and that of resource availability was relatively strong. Resource availability is relatively more important than allelopathy in mediating the reduction in plant biodiversity. Therefore, water and nutrient availability and the species and number of allelochemicals released by plants have substantial influences on the survival and growth of plant species in a natural Dacrydium forest.
