Fig mosaic

Fig mosaic disease is a serious viral infection caused by the pathogen Emaravirus fici. This virus is known to be systemic, meaning it spreads throughout the vascular system of the host plant, causing long-term physiological stress and growth impairment.

The primary host for this virus is the common fig (Ficus carica). The disease is distributed globally, affecting both commercial fig orchards and ornamental plantations, leading to substantial economic losses due to reduced fruit quality and decreased tree vigor over time.

Symptoms of the infection typically include chlorotic spotting on leaves, resulting in a mosaic pattern of yellow and green areas. In more severe cases, growers may observe leaf distortion, stunted growth, ring-spot patterns, and premature leaf or fruit drop, which significantly weakens the tree.

The virus is primarily transmitted by the fig mite (Aceria ficus). These microscopic pests acquire the virus while feeding on infected plant tissues and subsequently transmit it to healthy plants. Transmission efficiency increases in environments favorable to mite development, such as sheltered or warm conditions.

Effective management and prevention strategies include the following actions:

• Selection of certified virus-free propagating material for new plantings.
• Strict control of fig mite populations through regular application of recommended acaricides.
• Prompt removal and destruction of infected branches to reduce the inoculum pressure in the orchard.
• Implementing quarantine procedures for any new plant material introduced to the garden.
