“…Bacillus spp. are among the most widely used plant growth-promoting rhizobacteria, with B. subtilis and B. pumilus being among the ten most common species of bacteria registered as microbial plant biostimulants in several countries, including Canada [49]. In the present study, T. harzianum T-22 seed treatment increased the germination rate of baby leaf lettuce seeds at salinity levels of 40, 80, and 120 mM NaCl L −1 under organic or conventional growing systems and improved the shoot growth of baby leaf lettuce plants submitted to a salinity stress of 40 mM NaCl L −1 under organic management.…”

Plant biostimulants are substances or microorganisms aimed at promoting plant growth by increasing the mineral nutrition efficiency, tolerance to environmental stress, and crop quality traits. This new category of crop inputs has been capturing the interest of both researchers and agriculture takeholders in light of the promising effects they could have on crop productivity and sustainability. This study investigated a variety of biostimulants for their effect on germination rates, plant health, chlorophyll fluorescence parameters, SPAD index, and growth of baby leaf lettuce and Batavia lettuce submitted to biotic (absence/presence of Pythium ultimum in the growing medium) or abiotic (0, 40, 80, and 120 mM NaCl L−1 concentrations and −0.5, −2, −4, and −6 kPa water potentials) stresses when grown in a greenhouse under conventional and organic cultivation. The results obtained show that lettuce response to biostimulants was influenced by the type or level of stress applied and the growing system used. The effects of the tested biostimulants varied from strongly detrimental to strongly beneficial.

“…In the United States, plant biostimulants fall outside the categories of fertilizers [ 98 ] or pesticides, serving as enhancers of natural plant processes. Unlike conventional fertilizers and agrochemicals, these products do not have consistent global regulatory oversight, leading to uncertainty for developers and thus hindering commercialization and adoption [ 99 ].…”

“…Furthermore, hundreds of chemicals, including natural and synthetic antioxidant compounds, phytohormones and their functional analogs, and plant biostimulants, have been shown to activate plant antioxidant machinery and/or reduce ROS accumulation, thereby enhancing plant growth and productivity [14][15][16]. Additionally, methods employing microorganisms and stress-hardening procedures have also been reported to be effective in improving tolerance to oxidative stress [17].…”

Oxidative stress, resulting from the excessive production of reactive oxygen species, is a common and major cause of cellular damage in plants exposed to various abiotic stresses. To address this challenge, we introduce the concept of antioxidant agriculture as a comprehensive strategy to improve stress tolerance and thus crop productivity by minimizing oxidative stress levels in the field environment. This strategy encompasses a diverse range of approaches, including genetic engineering, the exogenous application of antioxidant agents, microbial inoculation, and agronomic practices, to reinforce the plant’s intrinsic antioxidant defense system and mitigate oxidative stress. We present recent successful studies of antioxidant measures that have been validated in field conditions, along with our perspective on achieving antioxidant agriculture.
