APPLE SCAB Meaning and
Definition
-
Apple scab is a plant disease caused by the fungus Venturia inaequalis that affects apple trees and other members of the Malus genus. It is a common and widespread problem in orchards, gardens, and landscapes where apple trees are grown. The term "scab" refers to the characteristic scaly lesions or irregular patches that form on the leaves, fruit, and twigs of infected trees.
Apple scab typically starts with small, olive-green or grayish-brown spots on the leaves, which gradually enlarge and darken over time. The affected areas become raised and develop a rough or corky texture, resembling scabs. As the disease progresses, it can also affect the fruit, causing blemishes, deformities, and cracking. Severe infections can lead to premature fruit drop and reduced crop yield.
The primary mode of dispersal for the apple scab fungus is through wind-borne spores. The spores overwinter on fallen leaves and infected fruit on the ground and infect new growth in the spring. Moisture, particularly during periods of rain or high humidity, promotes the development and spread of the disease.
Control and management of apple scab typically involve a combination of cultural practices, such as promoting good air circulation and removing fallen leaves and debris, and applying fungicides. Additionally, the use of resistant apple cultivars and regular monitoring for early signs of infection can help prevent and control apple scab. Employing integrated pest management strategies and practicing proper orchard hygiene are crucial for minimizing the occurrence and impact of this damaging fungal disease.

Etymology of APPLE SCAB
