STEM BLIGHT Meaning and
Definition
-
Stem blight is a plant disease characterized by the development of lesions or browning of the stems or branches of a plant. It is typically caused by various fungal pathogens, such as Botryosphaeria, Sclerotinia, or Phomopsis species, which infect the plant's vascular tissues, leading to wilting, reduced growth, and potential death of the affected plant.
The primary mode of transmission is through spores that are often spread by wind, rain, or through contact with infected plants or debris. The fungal pathogens typically gain entry into the plant through wounds, cracks, or natural openings in the stem, such as leaf scars.
Common symptoms of stem blight include the appearance of dark, sunken cankers or lesions on the stems, which gradually enlarge and extend along the stem. These lesions may be accompanied by the exudation of gummy or watery substances. Additionally, affected stems may show discoloration, wilting, or defoliation. In severe cases, the pathogen can invade the vascular tissues, blocking the flow of water and nutrients and resulting in the death of the entire plant.
To manage stem blight, it is crucial to employ prevention measures, including practicing good sanitation, such as removal and destruction of infected plant material, and avoiding plant stressors like over-fertilization or excessive pruning. Fungicides may also be applied as a preventive measure or as a curative treatment in early stages of the disease. Additionally, selecting resistant cultivars and promoting optimal plant health can help reduce the risk and severity of stem blight outbreaks.
