“…Excessive solar radiation and high temperatures can reduce growth and cause foliar chlorosis, oxidative stress, and impediments in photosynthesis. The company Atlántica Agrícola has developed a product named Archer ® Eclipse, formulated with CSL and calcium and zinc mineral salts, whose foliar application to cucumber plants (Cucumis sativus L.) prevents damage from leaf burns [51]. In a growth chamber, the researchers subjected the plants to sun and heat stress with a high-power sodium lamp placed 90 cm above the plants.…”

Biostimulants are substances or microorganisms that are applied to plants, soil, or seeds, to improve the growth, development, performance, and quality of crops. Their application is mainly directed towards improving the resistance of crops against abiotic and biotic stresses. These compounds are formulated from a great variety of compounds: humic substances, complex organic materials (sewage sludge extracts, composts, and manure), chemical elements (Al, Co, Na, Se, and Si), inorganic salts including phosphite, seaweed extracts (brown, red, and green), amino acids, etc. As of today, it has been observed that corn steep liquor (CSL), which is obtained from the industrial process of corn transformation, may be a good ingredient for the formulation of biostimulant products. CSL contains a large amount of different chemical compounds with biological activity for the plants and soil. The use of CSL industrial waste, previously formulated, could have a direct or indirect effect on the physiological processes and metabolic routes of plants related to the adaptation to abiotic and biotic stresses, as their compounds are part of these metabolic pathways, act as elicitor compounds, and/or have their own biological activity in the plants. There is evidence that the application of CSL could protect plants from specific abiotic and biotic stresses, such as an excess of light or temperature, nutritional limitations, salinity, drought, or pathogens. In addition, it can improve the growth of the plant when these are grown in hydroponic systems, and can improve the health of soils. The present article is focused on describing the most relevant scientific aspects of CSL when used as an ingredient to formulate biostimulants for agriculture. It will discuss its chemical composition, the analytical techniques utilized to elucidate and quantify its compounds, its uses in agriculture, and mode of action in the plants.

Mango is the most exported fruit of Brazil, especially grown in São Francisco Valley (tropical semiarid) where there is high temperatures and low air humidity, a condition that can cause stress to plants. Thus, the current study aimed to evaluate the effectiveness of different sunblocks to alleviate the abiotic stress of “Palmer” mango trees grown in a semiarid environment. The experimental design consisted of randomised blocks with six treatments, four repetitions and three plants per plot. The treatments consisted of different strategies of sunblocks as follows: (T1) control (no sunblock); (T2) calcium carbonate (50 g · L−1); (T3) sunblock (5 mL · L−1); (T4) sunblock (5 mL · L−1) + calcium carbonate (50 g · L−1); (T5) sunblock (5 mL · L−1) + sunblock silicon concentrated (20 mL · L−1) and (T6) sunblock (20 mL · L−1). The results indicate a clear action of sunblock in attenuating the abiotic stress of mango, with a persistent effect with time elapsing, considering the evaluated interval. The sunblock clearly promotes a differentiated leaf coverage pattern, protecting the photosynthetic apparatus and increasing its performance and consequently improving the production of plant reserves. The use of calcium carbonate individually promotes a very short protective effect, without positive reflexes after a few days of application. Mango fruit yield is affected by the sunblock with an increase of 4.2 t · ha−1 from the treatment with sunblock (20 mL · L−1) in relation to the control treatment.
