“…The efficacy of the two extracts was dose-dependent and varied with the tested pests and time in the planting season, with lower populations of the pests being observed later in the season. The incidence of P. cruciferae and D. undecimpunctata was also reduced in cucumber by aqueous extracts of A. indica and Zingiber officinale [116]. Aqueous extracts of T. vogelii at 5% w/v also reduced the infestation of aphids on beans in the field [113].…”

Phenolics from Medicinal and Aromatic Plants: Characterisation and Potential as Biostimulants and Bioprotectants

Biostimulants and bioprotectants are derived from natural sources and can enhance crop growth and protect crops from pests and pathogens, respectively. They have attracted much attention in the past few decades and contribute to a more sustainable and eco-friendly agricultural system. Despite not having been explored extensively, plant extracts and their component secondary metabolites, including phenolic compounds have been shown to have biostimulant effects on plants, including enhancement of growth attributes and yield, as well as bioprotectant effects, including antimicrobial, insecticidal, herbicidal and nematicidal effects. Medicinal and aromatic plants are widely distributed all over the world and are abundant sources of phenolic compounds. This paper reviews the characterisation of phenolic compounds and extracts from medicinal and aromatic plants, including a brief overview of their extraction, phytochemical screening and methods of analysis. The second part of the review highlights the potential for use of phenolic compounds and extracts as biostimulants and bioprotectants in agriculture as well as some of the challenges related to their use.biostimulant; bioprotectant; phenolic; medicinal; aromatic

“…From the present investigation, we could identify potential plant extracts and organic treatments that can be effectively used for insect pest management in organic soybean and Indian rape crops. Based on the previous studies conducted by several authors (Ahmed et al, 2010; Alao, 2015; Odewole et al, 2016; Odewole et al, 2020; Tembo et al, 2018), the locally available plant materials like seed extracts of M. azedarach and leaf extracts of P. hysterophorus , A. indica , L. camara and P. radiata were used in the study along with commercially available organic treatments like B. bassiana , M. anisopliae and Nimbicidine. The study revealed that, the noxious weed species P. hysterophorus showed anti‐feedant as well as insecticidal activity against C. choprai infecting soybean under both laboratory and field conditions.…”

“…Plant‐based insecticides or botanical insecticides stand out as a suitable alternative for insect pest control in organic production systems (Ahmed et al, 2010; Alao, 2015; Odewole, Adebayo, Babarinde, & Awolokun, 2020; Odewole, Adebayo, & Dada, 2016; Tembo et al, 2018). As many as 6,000 plants belonging to 170 families have been reported so far to be having insecticidal properties and that are exploited by farmers in developing countries (Ahmed et al, 2010; Khan et al, 2017; Koul, Walia, & Dhaliwal, 2008).…”

The present investigation was aimed to assess the best organic pest management practices in soybean and Indian rape cultivation systems in the mid-Himalayas. Based on the preliminary laboratory assays, promising treatments were selected for field assays for 3 years. It was observed that Parthenium leaf extract 5% provided significantly higher pest reduction in field condition with 76.8% at 7 DAT (days after treatment) against sucking bug, Chauliops choprai infesting soybean. In case of mustard aphids (Lipaphis erysimi) infesting Indian rape, Nimbicidine 5 ml L À1 was found superior with 61.5% pest reduction, followed by 5% seed extract of Melia azedarach at 7 DAT in field condition. Contrary to pest reduction, the pooled yield data analysis showed that among organic treatments, spraying of Nimbicidine @ 5 ml L À1 recorded significantly superior yield over control with yield advantage of 29%, followed by M. azedarach seed extract 5% and 10%, both recording 21% yield advantage in case of soybean. Nimbicidine was also superior for Indian rape crop with yield advantage of 51%, followed by Beauveria bassiana @ 3 g L À1 with 44% and 5% seed extract of M. azedarach with 33% yield advantage compared to control. Hence, Parthenium leaf extract 5% and Nimbicidine are recommended for effective control of C. choprai and L. erysimi infesting soybean and Indian rape, respectively. But to achieve higher yield, Nimbicidine is the best among organic management of those pests for both crops. These results suggest good organic pest management options in organic farming system.

“…Growing evidence highlights the potential of biocontrol interventions to reduce pest incidence and increase yield (Amoabeng et al 2020;Farsia Djidjonri et al 2021). For example, push-pull technology has been shown to be effective against a range of crop pests, particularly maize stemborers (Midega et al 2018), and plant-based botanical pesticides can reduce pest incidence and enhance yield in vegetables crops (Mpumi et al 2020;Odewole et al 2020).…”

Insect pests are a major challenge to smallholder crop production in sub-Saharan Africa, where access to synthetic pesticides, which are linked to environmental and health risks, is often limited. Biological control interventions could offer a sustainable solution, yet an understanding of their effectiveness is lacking. We conducted a meta-analysis of 5 commonly-used biocontrol interventions to quantify i) the magnitude of their effects when compared with no control and with synthetic pesticides, and ii) how effectiveness is determined by landscape composition. Overall, compared to no control, biocontrol interventions reduced pest abundance by 63%, crop damage by over 50%, and increased crop yield by over 60%. Compared to synthetic pesticides, biocontrol produced comparable yields, and natural enemy abundance was 43% greater. Our results suggest that biocontrol represents an effective intervention for farmers who do not have access to pesticides, while it can maintain yields without associated negative pesticide effects. However, the potential for biocontrol to be affected by landscape composition is a critical knowledge gap in sub-Saharan Africa.
