dc.description.abstractRed leaf blotch of almond, caused by the fungus Polystigma amygdalinum, results in early defoliationof trees and decreases fruit production in many Mediterranean and Middle Eastern countries. A latent period of30–40 d has been reported for this pathogen before disease symptoms are expressed, which makes targeted fungicide control difficult. A quantitative real-time PCR detection method was developed to detect and quantify thefungus in biological samples, to assist early detection. A primer pair was designed based on the ITS region of thefungal rDNA, and this was highly specific and sensitive, enabling detection of a minimum of 12 pg of P. amygdalinum DNA and seven ascospores in artificially-prepared ascospore suspensions. A protocol was also developedto quantify ascospores on plastic tapes which are commonly used in volumetric air samplers. The detection limitfor these samples was the same as for ascospore quantification in aqueous suspensions. The pathogen was alsoquantified in naturally infected leaves showing different stages of disease development, including early stages ofleaf infection with doubtful visual identifications. Future practical applications of the method developed here arediscussed in view of improving the management of red leaf blotch of almond.ca
