[3] Peanuts are grown in warm areas, which determines where this disease is normally found. [4] It has created difficulties in countries such as Brazil and Argentina that are big peanut ...
Common scab, a plant bacterial disease caused by Streptomyces species; Fusarium head blight, a fungal disease of plants, e.g., grain crops (especially wheat and oats), golf course grass, caused by the several species of Fusarium; Pear scab, a pear fungal disease caused by Venturia pirina or Fusicladium pyrorum
While the disease can cause total crop loss in optimal conditions without management, the main economic impact is due to the reduction in both size and marketable quality of the fruit. This issue is further compounded by the fact that apple cultivars with a high market share, Pink Lady for example, are susceptible to the pathogen while more ...
Apple scab is a common disease of plants in the rose family that is caused by the ascomycete fungus Venturia inaequalis. [1] While this disease affects several plant genera, including Sorbus, Cotoneaster, and Pyrus, it is most commonly associated with the infection of Malus trees, including species of flowering crabapple, as well as cultivated apple.

[2] [3] Symptoms of powdery scab include small lesions in the early stages of the disease, progressing to raised pustules containing a powdery mass.
In fact, this disease doesn’t occur often in areas with less than 30 inches of rain per year. The chance of disease onset increases in areas that get more than 45 inches of rain per year. Such moist environments helps facilitate the vector's zoospore movement to the infection sites (roots and tubers). It is thought that powdery scab disease ...
