“…[ 50 ]. On the other hand, citrus greening was also reduced by a reduction of the pest Diaphorina citri upon treatment with extracts of Caulerpa sertularioides , Laurencia johnstonii and Sargassum horridum [ 51 ]. Additionally, seaweed extracts were able to significantly reduce infestation caused by borers, aphids, and thrips in sugarcane thus preventing great economic loss [ 52 , 53 ].…”

The use of seaweed-based bioproducts has been gaining momentum in crop production systems owing to their unique bioactive components and effects. They have phytostimulatory properties that result in increased plant growth and yield parameters in several important crop plants. They have phytoelicitor activity as their components evoke defense responses in plants that contribute to resistance to several pests, diseases, and abiotic stresses including drought, salinity, and cold. This is often linked to the upregulation of important defense-related genes and pathways in the plant system, priming the plant defenses against future attacks. They also evoke phytohormonal responses due to their specific components and interaction with plant growth regulation. Treatment by seaweed extracts and products also causes significant changes in the microbiome components of soil and plant in support of sustainable plant growth. Seaweed extracts contain a plethora of substances which are mostly organic, but trace levels of inorganic nutrient elements are also present. Fractionation of seaweed extracts into their components and their respective bioassays, however, has not yielded favorable growth effects. Only the whole seaweed extracts have been consistently proven to be very effective, which highlights the role of multiple components and their complex interactive effects on plant growth processes. Since seaweed extracts are highly organic, they are ideally suited for organic farming and environmentally sensitive crop production. They are also very compatible with other crop inputs, paving the way for an integrated management approach geared towards sustainability. The current review discusses the growth and functional effects evoked by seaweed extracts and their modes and mechanisms of action in crop plants which are responsible for elicitor and phytostimulatory activities. The review further analyses the potential value of seaweed extracts in integrated crop management systems towards sustainable crop production.

“…Seaweeds, with their great chemical diversity, are utilized as a foodstuff for human and animal food, fertilizers, cosmetics, and medicinal products [ 18 , 19 ]. Seaweed extracts have proven competence for controlling and repelling various insect pests such as cereal aphids, Schizaphis graminum [ 20 ], the cotton stainer bug, Dysdercus cingulatus [ 21 ], mosquitoes [ 22 , 23 ], the tomato moth, Tuta absoluta [ 24 ], the termite, Microtermes obesi [ 25 ], maize weevil, Sitophilus zeamais [ 26 ] and the Asian citrus psyllid, Diaphorina citri [ 27 ]. Some studies documented the insecticidal effects of seaweeds of Egyptian origin as Caulerpa prolifera , Caulerpa serrulata , Jania rubens , Nitophyllum punctatum Padina pavonica , Chara vulgaris, Parachlorella kessleri , Ulva intestinalis and Cladophora glomerata [ 28 , 29 ].…”

Phytochemical Investigation of Three Cystoseira Species and Their Larvicidal Activity Supported with In Silico Studies

Culex pipiens mosquitoes are transmitters of many viruses and are associated with the transmission of many diseases, such as filariasis and avian malaria, that have a high rate of mortality. The current study draws attention to the larvicidal efficacy of three methanolic algal extracts, Cystoseira myrica, C. trinodis, and C. tamariscifolia, against the third larval instar of Cx. pipiens. The UPLC-ESI-MS analysis of three methanol fractions of algal samples led to the tentative characterization of twelve compounds with different percentages among the three samples belonging to phenolics and terpenoids. Probit analysis was used to calculate the lethal concentrations (LC50 and LC90). The highest level of toxicity was attained after treatment with C. myrica extract using a lethal concentration 50 (LC50) of 105.06 ppm, followed by C. trinodis (135.08 ppm), and the lowest level of toxicity was achieved by C. tamariscifolia (138.71 ppm) after 24 h. The elevation of glutathione-S-transferase (GST) and reduction of acetylcholine esterase (AChE) enzymes confirm the larvicidal activity of the three algal extracts. When compared to untreated larvae, all evaluated extracts revealed a significant reduction in protein, lipid, and carbohydrate contents, verifying their larvicidal effectiveness. To further support the observed activity, an in silico study for the identified compounds was carried out on the two tested enzymes. Results showed that the identified compounds and the tested enzymes had excellent binding affinities for each other. Overall, the current work suggests that the three algal extractions are a prospective source for the development of innovative, environmentally friendly larvicides.

“…After dark incubation for two weeks, the samples were extracted four times and filtered. The methanol was concentrated by evaporation in a rotary evaporator (Labo-Rota C311) in water bath at (40 °C) for (2 _ 3) h. The crude methanolic extracts were weighed and kept in deep freezer (-4°C) until further use in experiments ( Gonzalez-Castro et al, 2019 ).…”
