## 1 Introduction  
Rice is not only one of the most important food crops worldwide, but also, together with maize and wheat [1], the staple food of more than half of the world's population, and it is of great value to the supply of human food [2]. Moreover, its high and stable yield is of great significance for ensuring food security [3]. It is well known that rice sheath blight, caused by _R. solani_ infection, is one of the most destructive rice diseases in the world [4]. It primarily occurs under high temperature and humidity conditions, and it has a wide host range and high competitive saprophytic ability, and its control is of great significance to national food security [5]. At present, the primary treatment method for rice sheath blight is the application of chemical fungicides, such as jinggangmycin and thiophanate-methyl. Although chemical control is effective, it also causes environmental pollution, and long-term and wide-ranging application will result in drug resistance and other negative effects on environmental ecology. In response to these challenges, researchers have endeavoured to use transgenic technology for biological control. However, this method poses other problems, such as the difficulty in screening antagonistic microorganisms, unstable control effects, and the danger of genetically modified food. Furthermore, no immune or high-resistance varieties have been found or developed thus far [6]. Pulsed electric field (PEF) technology, which is an emerging non-polluting sterilisation technology, is widely regarded and highly valued by domestic and foreign food technology experts and microbiologists. A PEF inactivates microorganisms through the use of a short-term electric field, which damages the structure and function of cells, thus enhancing the permeability of cell membranes [7]. This causes the selective permeability of the cell to be changed or lost, thus allowing for a large number of substances to infiltrate the cells, which results in cell apoptosis. Researchers worldwide have conducted considerable research on the lethal effects of a PEF on different microorganisms, focusing mainly on the effects of different PEF parameters (electric field strength, pulse duration, pulse number, etc.) on microbial lethal effects. For example, [PERSON] [8] treated Gram-negative bacteria (_Pseudomonas aeruginosa_) and Gram-positive bacteria (_Staphylococcus aureus_ and _Listeria innocua_) in whole milk with PEF, and found that Gram-negative bacteria were less tolerant of PEF treatment than Gram-positive bacteria. [PERSON] [9] studied the effect of PEF on the inactivation rate of _Saccharomyces cerevisiae_ cells in juice, and found that the inactivation effect depends on the combination of electric field parameters used, especially the pulse holding time and the number of pulses. [PERSON] [10] found that sub-millisecond pulse trains are more cost effective than longer ones in the use for bacterial inactivation in the flow process. In addition, [PERSON] [11] found that, after the application of a pulse voltage of 3 kV with a pulse duration of 15 us, the lethal rate reached 92.6% for _Aspergillus niger_ at 200 pulses, and all of the moulds were killed after 1000 pulses. Therefore, PEF has certain antibacterial effects on a variety of microorganisms, including Gram-positive bacteria, Gram-negative bacteria, yeasts, and moulds. Different strains have been reported to vary in their resistance to PEF; for example, [PERSON] [12] presented an investigation of the survival ratios of Gram-negative (_Escherichia coli_, _Yersinia enterocoltica_) and Gram-positive (_S. aureus_, _Listeria monocytogenes_) bacteria and yeast-like fungi (_Candida albicans_) following HV pulses with peak voltages that range from \(U=0\) to 100 kV, and rise time that ranges from \(t=0.5\) to 1.2 us. Mortality rates from high to low were as follows: Gram-negative bacteria \(>\)_S. aureus_\(>\) yeast-like fungi \(>\)_L. monocytogenes_.
