DETECTION OF PHYTOPATHOGENS ON COTTON SEEDS AND THEIR DISINFECTION USING AQUEOUS SOLUTIONS TREATED WITH LOW-TEMPERATURE PIEZOELECTRIC DIRECT DISCHARGE PLASMA

The effect of low-temperature plasma initiated by a piezoelectric direct discharge on biological and water-containing objects is a promising method for disinfecting planting material and regulating growth. The article shows that plasma-activated water created by this method significantly suppresses the activity of phytopathogens Xanthomonas citri pv. Malvacearum, Verticillium dahlia and Fusarium oxysporum f.sp. vasinfectum on cotton seeds. Phytopathogens were identified using real-time PCR and microscopy. A fluorescent method for detecting these phytopathogens has been developed for the effective use of aqueous solutions treated with low-temperature plasma in field conditions.
