Bacterial diseases of sorghum crops

Abstract

Goal. To analyze the data on the range of pathogens of sorghum bacterial diseases common in the world and assess the possibility of their introduction in Ukraine, and the lesion of sorghum crops by bacterial pathogens. Methods. General scientific (generalization, comparison, system analysis), field (visual inspection of sorghum crops), microbiological (isolation of bacteria from affected plants, study of physiological and biochemical properties of isolates). Results. The most common bacterial diseases of sorghum are the bacterial spot of sorghum (Pseudomonas syringae pv. syringae), the striped spot of sorghum (Xanthomonas vasicola pv. holcicola), the striatal spot of sorghum (Robbsia andropogonis). The main symptom of sorghum crops affected by bacteriosis pathogens are spots on leaves and stems. Symptoms typical of bacterial lesions on soriz leaves were found during the inspection of crops in farms of the Cherkasy region in 2019–2021. Conclusions. Phytopathogenic bacteria cause damage to sugar and grain sorghum in all countries where these crops are grown. A Survey of sorghum and soriz plantations for the presence of bacterial diseases should be carried out in July–September. New sorghum crop — soriz in the field is affected by the causative agent of bacterial spot sorghum Pseudomonas syringae pv. syringae.
