“…It was found that MnO 2 NPs at concentrations of 0.1-10 mg/L had a positive effect on the content of soluble sugars, chlorophyll a/b, and carotenoids in pea seedlings. These results align with the findings of Heena et al [32], suggesting that this effect may be attributed to the stimulation of photosynthesis processes. However, at a concentration of 100 mg/L, MnO 2 NPs likely disrupted the biochemical homeostasis in peas, leading to a significant decrease in the studied indicators of the photosynthesis intensity, which is consistent with findings of Pradhan et al [31].…”

“…Pradhan et al [31] studied the molecular, biochemical, and biophysical effects of Mn NPs on Vigna radiate, revealing the stimulation of photosynthesis processes. Additionally, Heena et al [32] highlighted the highly beneficial effects of Mn NPs on the growth, yield, and economics of garden peas, confirming the potential of treating peas with Mn nanoforms. However, all discussed works showed a potential toxic effect of Mn NPs at higher concentrations, underscoring the need for further experimentation and careful consideration when applying Mn nanoforms to peas.…”

This study aimed to synthesize, characterize, and evaluate the effect of cocamidopropyl betaine-stabilized MnO2 nanoparticles (NPs) on the germination and development of pea seedlings. The synthesized NPs manifested as aggregates ranging from 50–600 nm, comprising spherical particles sized between 19 to 50 nm. These particles exhibited partial crystallization, indicated by peaks at 2θ = 25.37, 37.62, 41.18, 49.41, 61.45, and 65.79°, characteristic of MnO2 with a tetragonal crystal lattice with a I4/m spatial group. Quantum chemical modelling showed that the stabilization process of MnO2 NPs with cocamidopropyl betaine is energetically advantageous (∆E > 1299.000 kcal/mol) and chemically stable, as confirmed by the positive chemical hardness values (0.023 ≤ η ≤ 0.053 eV). It was revealed that the interaction between the MnO2 molecule and cocamidopropyl betaine, facilitated by a secondary amino group (NH), is the most probable scenario. This ascertain is supported by the values of the difference in total energy (∆E = 1299.519 kcal/mol) and chemical hardness (η = 0.053 eV). These findings were further confirmed using FTIR spectroscopy. The effect of MnO2 NPs at various concentrations on the germination of pea seeds was found to be nonlinear and ambiguous. The investigation revealed that MnO2 NPs at a concentration of 0.1 mg/L resulted in the highest germination energy (91.25%), germinability (95.60%), and lengths of roots and seedlings among all experimental samples. However, an increase in the concentration of preparation led to a slight growth suppression (1–10 mg/L) and the pronounced inhibition of seedling and root development (100 mg/L). The analysis of antioxidant indicators and phytochemicals in pea seedlings indicated that only 100 mg/L MnO2 NPs have a negative effect on the content of soluble sugars, chlorophyll a/b, carotenoids, and phenols. Conversely, lower concentrations showed a stimulating effect on photosynthesis indicators. Nevertheless, MnO2 NPs at all concentrations generally decreased the antioxidant potential of pea seedlings, except for the ABTS parameter. Pea seedlings showed a notable capacity to absorb Mn, reaching levels of 586.5 μg/L at 10 mg/L and 892.6 μg/L at 100 mg/L MnO2 NPs, surpassing the toxic level for peas according to scientific literature. However, the most important result was the observed growth-stimulating activity at 0.1 mg/L MnO2 NPs stabilized with cocamidopropyl betaine, suggesting a promising avenue for further research.

“…Because EPNs and their host insects coevolve in nature, their relevant genes have supposedly balanced co-existence for encoding via the attacking and defending interactions exerted by the EPNs and the invaded insects, respectively. Although EPN reproduction is possible only if their metabolism is shifted to enable infectivity (power to invade), reproductive capacity (yield per insect) and virulence (power to kill), the processes of EPN feeding and recycling comprise various morpho-histological, physiological and biochemical aspects [58][59][60]. Basic research is required to examine the genetic architecture of key traits, e.g., stress tolerance, infectivity and reproduction [61].…”

Entomopathogenic nematodes (EPNs) can kill and recycle in their host populations, which bodes well for EPNs’ exploitation in long-term and safe pest management. However, EPNs’ cost and efficacy need transformational technology to supplant less expensive and more effective but toxic/unhealthy pesticides. A technology that allows for the significant uptake of commercial EPNs should both boost their market suitability and provide genetic improvements. This review provides brief overviews of EPNs’ biology and ecology from the standpoint of pest/pathogen management as a prerequisite for EPN improvements. Understanding the biology and ecology of EPNs, particularly their symbiotic relationships with bacteria, is crucial to their effective use in pest management. This review provides relevant insights into EPN-symbiotic bacteria and the EPN–symbiont complex. The symbiotic relationship between EPNs and bacteria plays a key role in IPM, providing unique advantages. Either of them can be included in mechanisms underlying the various positive sides of plant–insect interactions in emerging integrated pest management (IPM) systems. Recent approaches, in which EPNs can act additively or synergistically with other production inputs in IPM programs, are discussed for further expansion. The simultaneous favorable effects of EPNs and/or their mutualistic bacteria on several pest/pathogen species of crops should be identified. Merits, such as the rapid killing of insect pests, ease of EPN/the symbiont’s mass production and a broad host range, are presented in order to widely disseminate the conditions under which EPN usage can offer a cost-effective and/or value-added technique for IPM. To maximize the effectiveness of EPNs in IPM, various genetic improvement techniques are being explored. Such techniques, along with their merits/demerits and related tools, are reviewed to optimize the common biocontrol usage of EPNs. Examples of genetic improvements to EPNs that allow for their use in transformational technology, such as a cost-effective application technique, increased infectivity, and toleration of unfavorable settings, are given. Proper production practices and genetic techniques should be applied carefully to avoid undesirable results; it is suggested that these are considered on a case-by-case basis. This will enable us to optimize EPN performance based on the given variables.

“…Cherotich and Kaur (2021) and Rochelle et al [16] reported on use of unverified water by farmers. Water conservation is not a priority for most farmers as most make decisions based on personal judgments arising from practical experience [17,18,19]. A study by Rehman [20] however showed that most farmers had an awareness of different water management practices.…”

Good Agricultural Practices (GAP) towards ensuring vegetable safety and quality is a novel concept among Kenyan vegetable growers with its implementation low due to lack of awareness. To bridge this gap, this study sought to determine the socio-economic characteristics that affect GAP awareness among vegetable farmers in Nakuru, Kenya. Simple random sampling was used to select 100 vegetable growers. Logistic regression was used for analysis and the findings reveal that gender, level of education, leased land, income and training significantly influenced awareness. Emphasis on awareness creation among female vegetable growers and capacity building through training on GAP standards is suggested as a way forward in order to increase implementation.
