Citrus virus and virus-like diseases are the major causes of citrus decline in Pakistan. Citrus tristeza virus (CTV) is of utmost concern. Although CTV has been identified and characterized on the basis of serological and physical properties, no information is available on the strains of CTV in Pakistan. The identification of CTV strains will be helpful in developing strategies to control the decline of citrus trees to a great extent. Many citrus growing countries have successfully used the technique of cross protection to minimize the drastic effect of severe CTV strains. The decline can be controlled to increase the life span of the citrus tree by pre-immunization of the citrus tree with mild strains. We focus on the possibility of establishing a cross protection technique in Pakistan against the CTV strains.
