“…According to Yakhin et al (2017), biostimulants are natural stimulants, organic compounds, biostimulators, or plant growth regulators. The term "biostimulants" was first used in 1951 (Yakhin et al, 2017), but only in the past 25 years have researchers investigated how biostimulants might lessen the effects of global climate change (Yakhin et al, 2017;Rai et al, 2021;Khetsha et al, 2023). Due to recent extreme temperatures and weather patterns, abiotic stresses, such as drought, are becoming increasingly significant threats to food production.…”

“…The positive effects of plant biostimulants with traces of phytohormones on yield, fruit diameter, length, chlorophyll content, and overall functional quality have been reported on horticultural crops such as tomato, pepper (Capsicum annuum L.) and spinach (Spinacia oleracea L.) (Turan et al, 2021). Biostimulants have been authenticated to encourage the growth and development of plants, as well as pathogen defense and decrease the spread and severity of some diseases (Khetsha, 2020;Habib et al, 2021;Turan et al, 2021;Ramzan and Younis, 2022).…”

“…However, much has been extensively researched on single stress factors, lacking novelty. Khetsha et al (2020;2023) also reported explicitly on the recovery response mechanism of a simulated hail-damaged medicinal and aromatic plant, Pelargonium graveolens (L.), using bio-inhibitors; promising future research to explore under adverse multi-stress factoring for vegetables. Therefore, new novel approaches using organic plant-based/phytohormones-based biostimulants are the eco-friendly approaches to explore, as described by Habib et al (2021).…”

Worldwide, it has been recorded extensively that plants are subjected to severe abiotic and biotic stressors. The scientific research community has widely reported that multi-abiotic stressors cause horticultural crop losses, accounting for at least 50 to 70% of the crop yield and quality losses. Therefore, this review focused on the detrimental effects caused by abiotic stress factors occurring in single-, combined- and multi-cell stresses on horticultural plants worldwide, along with the best production systems practices for mitigation during and post-single and combined abiotic or multi-stress damages. A conclusion and recommendation could be reached using the pool of research material, which constituted research articles, reviews, book chapters, thesis, research short communications and industrial short communications from at least twenty-five years ago. Findings showed that some of the leading abiotic stresses are single- and combined abiotic stressors like water deficit, salinity, soil pH, phosphate deficiency, wounding, soil density and pot size. Established commercial and smallholder farmers are globally adapting to plant growth regulators and biostimulants as part of their production systems. However, as much as the effectiveness of biostimulants containing humic acids, algal extracts, plant growth-promoting microorganisms and phytohormones has been reported to promote plant development under multi-stress, only a few studies are focusing on organic phytohormone-based biostimulants on horticultural crops grown under adverse multi stress factoring. In conclusion, the review recommends alternative solutions for emerging South African farmers and growers who cannot afford agricultural insurance options and energy alternatives on the common single- and combined abiotic- or multi-stress-factors.

“…Agriculture is adapting to the variability in global climatic conditions, with farmers continually developing strategies to respond to changing weather patterns [2]. Aromatic and medicinal plants are among those plants which are negatively affected by climate change [3]. In addition, there is a concern over climate change affecting the secondary metabolites of many medicinal and aromatic plants [4].…”

Using Biostimulants Containing Phytohormones to Recover Hail-Damaged Essential Oil Plants

Revisiting Plant Biostimulants

Hail can cause significant damage to aromatic and medicinal plants; however, this has never been investigated scientifically on most of aromatic and medicinal plants. Globally, essential oil crop producers primarily make use of agricultural crop insurance and costly mitigation strategies to recover lost production costs and alleviate hail-damaged plants. However, most aromatic and medicinal plants are not covered under agricultural crop insurance, and many commercial farmers are not able to regularly employ expensive alternative strategies. Therefore, hail damage may present a challenge to essential oil growers. The use of natural and synthetic phytohormones in a form of biostimulants, as an alternative biological mitigation strategy against hail damage in essential oil crops, has not received much attention, and there is no information on this topic. Exogenous applications of natural and synthetic biostimulants have consistently demonstrated growth enhancement, nutrient acquisition, yield and quality optimization, as well as physiological efficiency in plants. Biostimulants in a form of phytohormones are involved in diverse plant physiological processes, including the regulation of gene expression for adaptive responses to biotic and abiotic stresses. Using biostimulants, this chapter will detail the potential recovery response of aromatic and medicinal plants to hail damage, and the response of plants treated with biostimulants.
