In order to reduce the environmental burden of chemicals, various new alternatives to seed protection are being sought. Our aim was to find an environmentally acceptable solution leading to the inactivation of seed-borne phytopathogenic fungi Fusarium culmorum on the surface of wheat and barley seeds with a positive effect on their germination. As a low-temperature plasma (LTP) source, a Diffuse Coplanar Surface Barrier Discharge (DCSBD) was used. Plasma generated by DCSBD is non-equilibrium, cold, diffuse, macroscopically homogeneous even in ambient air at atmospheric pressure. Experimental results showed that LTP treatment in the range of 120—300 s significantly inhibits the growth of F. culmorum on the surface of the seeds. The efficiency of LTP treatment was compared with traditional seed protection processes using chemical fungicide and also with combined seed pretreatment by plasma and subsequent application of chemical fungicide. No growth of F. culmorum was observed after the combination of Vitavax 2000 fungicide application in the dose of 10 % and 60 s of LTP treatment even on the 5th day of incubation. Better wettability of seeds with the chemical fungicide was related to the change on seed surface, which becomes hydrophilic after 10 s of LTP application. Short LTP exposure times did not affect germination and improved the growth parameter of cereal seeds. By combining physical (LTP) and chemical (Vitavax 2000) treatments of cereal seeds, it is possible to effectively reduce the required amount of chemical fungicide and to stimulate germination and early growth seed parameters.

“…Ascophyllum nodosum enhanced foliar resistance to Phytophthora capsici in pepper [49]. SWE, applied as a soil drench to pepper plants, reduced Verticillium wilt of pepper through improving plant fitness and increasing resistance to pathogens [50]. Spatoglossum variabile, Stokeyia indica, and Melanothamnus afaqhusainii extracts showed significant suppressive effect on root rotting fungi Fusarium solani and root knot nematode Meloidogyne incognita in eggplant [51].…”

Seaweeds are one of the important marine bioresources which are nowadays termed as eco-friendly stimulators of crop growth, stress tolerance, and yielding. In this review, we give an update of the current state of our understanding of the seaweed extracts (SWE) effects on the physiological alterations they induce in Solanaceae vegetables. SWE may provide a powerful and environmentally friendly approach to nutrient management. A pool of common bioactive molecules of SWE provides enhancement of the antioxidant machinery of treated plants providing balanced development, earlier flowering, and enhanced fruiting. The basic mechanisms of SWE action seem to be unspecific for tomato, pepper, and eggplant. They include accelerating growth, nutrient uptake, and photosynthesis performance, which can induce plant tolerance to adverse environmental conditions, improve flowering, fruit setting, and yield, and enhance nutritional quality of the crops. The mechanism of SWE action is complex because of multielement composition and cross-action between constituents.

Potato Verticillium wilt, caused by Verticillium dahliae, is a serious soil-borne vascular disease, which restricts the sustainable development of the potato industry, and the pathogenic mechanism of the fungus is complex. Therefore, it is of great significance to explore the important pathogenic factors of V. dahliae to expand the understanding of its pathology. Protein kinase C (PKC) gene is located in the Ca2+ signaling pathway, which is highly conserved in filamentous fungi and involved in the regulation of a variety of biological processes. In the current study, the PKC gene in V. dahliae (VdPKC) was characterized, and its effects on the fungal pathogenicity and tolerance to fungicide stress were further studied. The results showed that the VdPKC positively regulated the growth and development, conidial germination, and production of V. dahliae, which was necessary for the fungus to achieve pathogenicity. It also affected the formation of melanin and microsclerotia and changed the adaptability of V. dahliae to different environmental stresses. In addition, VdPKC altered the tolerance of V. dahliae to different fungicides, which may be a potential target for polyoxin. Therefore, our results strongly suggest that VdPKC gene is necessary for the vegetative growth, stress response, and pathogenicity of V. dahliae.
