Bacterial Citrus Canker

Citrus Bacterial Canker Disease and Huanglongbing (Citrus Greening)

IntRODUctIOn Compared with the rest of the world, the California citrus industry is relatively free of diseases that can impact growers’ profits. Unfortunately, exotic plant pathogens may become well established before they are recognized as such. This is primarily because some of the initial symptoms mimic other diseases, mineral deficiencies, or toxicities. In addition, development of disease...

Control Measures for Citrus Bacterial Spot in Nurseries and Packinghouses

Citrus bacterial spot (CBS), caused by Xanthomonas campestris pv. citrumelo, produces unsightly blemishes on leaves and stems of nursery plants that may affect their mar ket value. In simulated nurseries, Swingle citrumelo and 'Ruby red' grapefruit infected with X. c. citrumelo were treated with combinations of defoliation and sprays of copper ammonium complex (CAC) to control CBS. Also, Swingl...

Quantitative PCR method for diagnosis of citrus bacterial canker.

For diagnosis of citrus bacterial canker by PCR, an internal standard is employed to ensure the quality of the DNA extraction and that proper requisites exist for the amplification reaction. The ratio of PCR products from the internal standard and bacterial target is used to estimate the initial bacterial concentration in citrus tissues with lesions.
