Apple chlorotic leafspot virus (ACLSV) is a virus that affects apple trees, causing the disease known as chlorotic leaf spot virus. This virus is primarily spread by infected wood grafts and shoots, as well as by mechanical transmission through contaminated pruning tools and other agricultural equipment. The virus can remain latent in the plant for long periods, becoming activated under specific conditions.
SYMPTOMS
Chlorotic leaf spot virus can cause various symptoms in apple trees, such as chlorotic Taches on the leaves, affecting photosynthesis and plant growth. It can also cause delayed growth and fruit development, as well as fruit deformities.
• Chlorotic Taches on the leaves.
• Delay in plant growth.
• Decrease in the quality and quantity of fruits.
• Deformities in the fruits.
• Reduction of photosynthesis and general vigor of the plant.
