Breeding for citrus black spot resistance

Acta Horticulturae
Citrus black spot (CBS) has caused problems in summer rainfall regions of Australia for more than 125 years with associated research focused on chemical and to a lesser extent cultural control strategies. This research has produced only partial and short-term solutions to the problem. More recently we shifted our attention to finding genetic resistance

Detection of citrus black spot symptoms using spectral reflectance

Postharvest Biology and Technology, 2021
Abstract Citrus black spot (CBS) disease can usually result in fruit blemish and yield loss on all citrus. Spectral reflectance was utilized to detect CBS symptoms in this study. Hyperspectral images of both healthy and diseased citrus were collected in the spectral region of 396−1010 nm. After raw image calibration, spectral reflectance of diseased (

Tree age and cultivar-oriented use of mineral oil added to fungicide tank mixture for the control of citrus black spot in sweet orange orchards.

Pest Management Science, 2021
BACKGROUND Mineral oil added to fungicide spray mixtures has been a frequently used strategy to control citrus black spot (CBS) worldwide. Although mineral oil may increase the efficacy of control, its use represents around 15% of the costs of CBS spray ...
