White Rust of Crucifers (With Diagram) - Biology Discussio

Introduction to the White Rust of Crucifers: White rust or white blisters disease is one of the common diseases of crucifer crops. It is worldwide in distribution occurring in all the areas wherever crop is cultivated. Both wild and cultivated varieties are attacked crucifers wherever these vegetables grow. The disease was reported in Hawai'i as early as 1918 (Department of Agriculture, State of California, Monthly Bulletin, Vol. 9). White rust was given its name due to the white pustules that form on the underside of infected leaves (Reddy 1996). Albugo candida is an obligate biotrop

Symptoms : • All parts affected except roots (1). Local infection • Leaves, stem, flower stalk - white /creamy, yellow blister like pustules (1-2 mm) • Powdery growth. Sources for white blister infection can include diseased plants or crops, volunteer crucifers, wild crucifers, cruciferous weeds and crop debris. White blister can be spread by wind, rain or by insects dispersing aerial spores. General conditions for white blister infection include: Rain splash of spores from soil onto the plan

  1. White rust of crucifers is a disease caused by the oomycete Albugo candida. It is also called as white blisters disease. Plants belonging to Brassica family are highly susceptible to this disease. Thus, the correct answer is option C
  2. White rust is a common but usually not serious disease. It is characterized by both local and systemic symptom expression. Local infection appears as pustules or blisters filled with sporangia on leaves, smaller stems, and floral parts. Pustules measure approximately 1 to 2 mm in diameter and are white or creamy yellow
  3. While crucifers grown for production of leafy greens are usually direct seeded; nearby gardens, transplanted fields, and diseased fields also can serve as sources of the bacterium. Numerous small, white, blister-like pustules are scattered on the undersides of leaves (Figure 11). The pustules, which contain spores of the fungus, appear as a.
  4. Cruciferous plant diseases are those that attack members of the Brassicaceae family such as broccoli, cauliflower, kale, and cabbage.White spot fungus is one such disease that favors the loose leaves of these vegetables and is therefore more of a threat to spinach, kale, and turnips than the tight head of cabbage or the flower heads of cauliflower and broccoli
