Some Factors Affecting Vinca (periwinkle) Root Rot Disease
Year: 2024
Type: article
Abstract: This study highlights the influence of different mineral fertilizers on the incidenceand severity of vinca (Periwinkle; Catharanthus roseus (L.) G. Don) root rot disease. Moreover, itdemonstrates the effectiveness of some chemical fungicides in reducing disease parameters. Thisresearch provides valuable insights for the development of effective fertilization strategies to enhanceplant health and mitigate the impact of root rot diseases in vinca. Ammonium Sulfate ((NH4)2SO4)completely inhibited disease parameters and consistently increased plant growth parameters.Potassium and Humate potassium have limited efficacy. Rizolex-T and Occidor fungicidesdemonstrated complete inhibition against all tested fungi (F3(Fusarium solani; Fx3(Fusariumproliferatum); Rh.x (Rhizoctonia solani L.) and Rh.w ( Rhizoctonia solani 2) on PDA media, whileUniform and Nasrzole showed varying degrees of effectiveness depending on the tested fungi. In vivo,the application of fungicides has varying degrees of efficacy in preventing infection with vinca root rotpathogens. Rizolex-T, was effective against most pathogens, exhibited a partial effect againstFusarium proliferatum. Occidor demonstrated good efficacy against Rhizoctonia solani 2 but was lesseffective against Fusarium solani. Nasrzole showed overall effectiveness in preventing infection by alltested pathogens, with only partial efficacy against Rhizoctonia solani 2. The application offungicides, particularly Nasrzole, positively influenced the growth parameters of vinca plants infectedwith root-rot pathogens.
