Control of Alternaria brown spot of Minneola tangelo with fungicides

Crop Protection, 1997
Abstract Field experiments to control fruit lesions of Alternaria brown spot ( Alternaria alternata pathovar citri ) of Minneola tangelo ( Citrus reticulata × C. paradisi ) were conducted over a period of 5 years. Iprodione at 0.5 g a.i. l − 1 was consistently effective in reducing fruit lesions when sprayed four or five times at 2 week ...

Diagrammatic scale for assessment of alternaria brown spot severity on tangerine leaves

Journal of Plant Pathology, 2019
Alternaria brown spot (ABS) is one of the main diseases of tangerine worldwide. It is necessary to use a practical and reliable method to quantify the disease severity of ABS and thus suggest management strategies. Thus, a diagrammatic scale (DS) constructed with color photographs was developed and validated to quantify the disease severity.

The effect of runoff on spray deposition and control of Alternaria brown spot of mandarins

Australasian Plant Pathology, 2009
Alternaria alternata pv. citri is the causal agent of Alternaria brown spot on tangerines and their hybrids and infects young leaves and fruit of all ages. In South Africa, repeated high volume (∼9000 L/ha) fungicide sprays on susceptible cultivars are the only effective control measure of this disease.
