Brassica oleracea L. (Cauliflower Group)
Cauliflower tissue necrosis manifests as a symptom of infectious lesions caused by pathogens or as an independent physiological disorder associated with imbalances in mineral nutrition and storage conditions.
In the reference 5 varieties crop Cauliflower, where this is mentioned in the description.
Infectious necrosis occurs with black rot (pathogen Xanthomonas campestris pv. campestris), manifesting as vein blackening and wilting, with bacterial soft rot (Pseudomonas maculicolum), leading to tissue decay, as well as with viral mosaic, where tissue necrosis is caused by the action of viral toxins.
Physiological tipburn is a non-infectious disorder characterized by the appearance of sunken lead-gray or black spots on the leaves, ranging from 0.5 to 5 mm in size. The main causes of development are deficiencies in calcium, boron, and molybdenum, an excess of nitrogen, as well as unfavorable storage conditions at low temperatures.
