Biocontrol Activity of Aromatic and Medicinal Plants and Their Bioactive Components against Soil-Borne Pathogens

Plants, Journal Year: 2023, Volume and Issue: 12(4), P. 706 - 706

Published: Feb. 5, 2023

Soil-borne phytopathogens can have detrimental effects on both cereal and horticultural crops resulting in serious losses worldwide. Due to their high efficiency easy applicability, synthetic pesticides are still the primary choice modern plant disease control systems, but stringent regulations increasing environmental concerns make search for sustainable alternatives more pressing than ever. In addition incorporation of botanicals into agricultural practices, diversification cropping systems with aromatic medicinal plants is also an effective tool diseases through providing nutrients shaping soil microbial communities. However, these techniques not universally accepted may negatively affect fertility if application thoroughly controlled. Because biocontrol potential has been extensively examined over past decades, present study aims overview recent literature concerning biopesticide effect secondary metabolites derived from important soil-borne pathogens including bacteria, fungi, nematodes. Most investigated herbs belong family Lamiaceae (e.g., Origanum spp., Salvia Thymus Mentha etc.) associated potent antimicrobial activity, primarily due chemical constituents. The most frequently tested organisms include such as Rhizoctonia Fusarium Phytophthora which be highly persistent soil. Despite intense research efforts dedicated development plant-based pesticides, only a few species utilized production commercial formulations inconsistent efficiency, lack field verification, costs, prolonged authorization requirements. recycling wastes plant-utilizing industries offer economically feasible way improve health reduce burdens at same time. Overall, this review provides comprehensive knowledge herb-based protection techniques, it highlights importance exploiting residues generated by sectors part agro-industrial processes.

Plants due to the high content of various bioactive compounds are main raw material for production valuable, and useful bio-products (e.g., food, cosmetics, medicines, biostimulants, biopesticides, feed). Different plant parts, instance: seeds, fruits, flowers, stems, leaves, roots can be used their manufacture. Nowadays, there is a clear need develop new, efficient, environmentally safe methods stimulation plant, growth crop protection. Plant-based extracts natural, multi-compounds products that could these purposes. They possess antifungal, antimicrobial, antiparasitic, antiprotozoal, antioxidant, medicinal, aromatic, anti-inflammatory properties. This group natural has potential become new generation suitable use in sustainable agriculture. The purpose this review provide an overview literature describing impact plant-derived extracts/biostimulants (PDBs) on crops grown controlled, real conditions as well under abiotic biotic stresses; extraction obtain PDBs, specific constituents responsible biostimulating activity. application beneficial production, several advantages, such low toxicity humans environment, enhanced resistance cultivated plants stress, increased yields quality crops, reduction mineral fertilisers pesticides.

Plant Essential Oils as Biocides in Sustainable Strategies for the Conservation of Cultural Heritage

Sustainability, Journal Year: 2023, Volume and Issue: 15(11), P. 8522 - 8522

Published: May 24, 2023

Biodeterioration is a complex network of interactions between macro/micro-biological systems and organic/inorganic substrates involving physical chemical alterations, strictly related to their metabolic activities. Concerning microbial deterioration, finding correct approach counteract this process often difficult, requiring an understanding the kind alterations use methods that respect artwork human environmental health. Specific conservative remedial are used for aim. They comprise physical, mechanical, methods, as well as, frequently, synthetic biocides, which have obvious limitations because toxicity operators or they contain polluting substances persist in natural environment. New alternative research has strongly focused on strategies replace toxic with products do not undesired effects, implementing safe, novel compounds. Several plants compounds such oils, phenols, flavonoids, alkaloids, coumarins, tannins, etc., commonly drugs, bioactive molecules, nutrients.
