“…The advantage of using biomass contained in plant extracts is its low cost (Tembo et al, 2018 ). Conversion of plant biomass in plant extracts, showing the action of biostimulants or plant growth, can be supportive to farmers in developing countries that cannot afford synthetic biostimulants, because of their high costs (Fite et al, 2020 ).…”

There are many technological innovations in the field of agriculture to improve the sustainability of farmed products by reducing the chemicals used. Uses of biostimulants such as plant extracts or microorganisms are a promising process that increases plant growth and the efficient use of available soil resources. To determine the effects of some biostimulants' treatments on the photosynthetic pigments and biochemicals composition of zucchini plants, two experiments were conducted in 2019 and 2020 under greenhouse conditions. In this work, the effects of beneficial microbes (Trichoderma viride and Pseudomonas fluorescens), as well as three extracts from Eucalyptus camaldulensis leaf extract (LE), Citrus sinensis LE, and Ficus benghalensis fruit extract (FE) with potassium silicate (K2SiO3) on productivity and biochemical composition of zucchini fruits, were assessed as biostimulants. The results showed that E. camaldulensis LE (4,000 mg/L) + K2SiO3 (500 mg/L) and T. viride (106 spore/ml) + K2SiO3 (500 mg/L) gave the highest significance yield of zucchini fruits. Furthermore, the total reading response of chlorophylls and carotenoids was significantly affected by biostimulants' treatments. The combination of K2SiO3 with E. camaldulensis LE increased the DPPH scavenging activity and the total phenolic content of zucchini fruits, in both experiments. However, the spraying with K2SiO3 did not observe any effects on the total flavonoid content of zucchini fruits. Several phenolic compounds were identified via high-performance liquid chromatography (HPLC) from the methanol extracts of zucchini fruits such as syringic acid, eugenol, caffeic acid, pyrogallol, gallic acid, ascorbic acid, ferulic acid, α-tocopherol, and ellagic acid. The main elemental content (C and O) analyzed via energy-dispersive X-ray spectroscopy (EDX) of leaves was affected by the application of biostimulants. The success of this work could lead to the development of cheap and easily available safe biostimulants for enhancing the productivity and biochemical of zucchini plants.

“…An additional advantage of plant biomass is its low cost. Conversion of plant biomass into extracts, showing the action of biostimulants of plant growth or biopesticides, can be crucial for poor farmers in developing countries who cannot afford synthetic biostimulants, plant protection products due to their high costs (Fite et al, 2020). The importance of using readily available and cheap natural resources for plant cultivation should be emphasised (Jang and Kuk, 2019).…”

“…The use of bitter leaf (Vernonia amygdalina) and Mexican sunflower (Tithonia diversifolia) bio-products can be useful in the control of selected pests e.g., flea beetles (Podagrica uniforma, P. sjostedti), aphids (Aphis fabae), flower beetles (Epicauta albovittata and E. limbatipennis), foliage beetles (Ootheca mutabilis and O. bennigseni), and cowpea beetle (Callosobruchus maculatus) (Onunkun, 2012;Mkenda et al, 2015;Green et al, 2017;Tembo et al, 2018). The application of neem (Azadirachta indica) products was found to be efficient against aphid species (Sitobion avenae, Schizaphis graminum, Rhopalosiphum padi), cotton bollworm (Helicoverpa armigera), and fall armyworm (Spodoptera frugiperda) (Shah et al, 2017;Zuleta-Castro et al, 2017;Fite et al, 2020). Extracts obtained from pawpaw (Carica papaya) leaf, stem bark, root, and flower showed good potential as bio-insecticide for protecting stored maize (Zea mays) grains against maize weevil (Sitophilus zeamais) (Adenekan et al, 2020).…”

Plant extracts - importance in sustainable agriculture

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

Global demand for food production is causing pressure to produce faster and bigger crop yields, leading to a rampant use of synthetical pesticides. To combat the nefarious consequences of its uses, a search for effective alternatives began in the last decades and is currently ongoing. Nature is seen as the main source of answers to crop protection problems, supported by several examples of plants/extracts used for this purpose in traditional agriculture. The literature reviewed allowed the identification of 95 plants whose extracts exhibit insecticide activity and can be used as bio-pesticides contributing to sustainable agriculture. The option for ethanol and/or water extracts is more environmentally friendly and resorts to easily accessible solvents, which can be reproduced by farmers themselves. This enables a bridge to be established between raw scientific data and a more practical reality. Azadirachta indica, Capsicum annuum, Nicotiana tabacum and Tagetes erecta are the most researched plants and have the potential to be viable options in the pest management approach. Azadirachta indica showed the most promising results and Brevicoryne brassicae was the most targeted pest species, being tested against the aqueous and/or ethanolic extracts of 23 different plants. Maceration using dried material (usually leaves) is the extraction method preferred by the majority of authors.
