Use of biostimulants for stimulating plant growth and mitigating the negative impacts
of biotic and abiotic stresses is a promising strategy to achieve higher crop yields. Fungicides such
as azoxystrobin are used to control several pests and fungal diseases in plants but at the cost of
altering various physiological processes; thereby, leading to reduced crop yields. The efficiency
of the compound RAZORMIN® as a biostimulant product while taking into account its role in
plant growth stimulation and fungicide azoxystrobin stress mitigation was evaluated in this study.
The efficacy of RAZORMIN® was assessed considering its impact on the stimulation of growthrelated
physiological processes and stress mitigation mechanism, e.g., reactive oxygen species (ROS)
detoxification. Application of RAZORMIN® significantly increased plant growth by improving fresh
weight, photosynthetic efficiency, net photosynthesis rate, gas exchange, nitrogen (N) metabolism
(with increases in soluble amino acids, foliar N concentration, and N use efficiency), growth hormone
concentrations (mainly gibberellins and cytokinins), nutritional status of plants (producing a greater
accumulation of phosphorus, potassium, calcium, magnesium, sulfur, zinc, molybdenum, iron, and
boron), and sugars concentration. Furthermore, the application of RAZORMIN® on plants under
fungicide azoxystrobin stress demonstrated its anti-stress and protective role by stimulating the
antioxidant defense system and improving photosynthetic efficiency
