“…Under these circumstances, crop rotation is recommended. An optimal interval for the rotation is 2 years for potato, 61 , 62 while 3‐ to 5‐year crop rotation is recommended for tomato. 5 The underlying reasons for the difference in the duration was not found in the literature.…”

Alternaria species are well‐known aggressive pathogens that are widespread globally and warmer temperatures caused by climate change might increase their abundance more drastically. Early blight (EB) disease, caused mainly by Alternaria solani, and brown spot, caused by Alternaria alternata, are major concerns in potato, tomato and eggplant production. The development of EB is strongly linked to varieties, crop development stages, environmental factors, cultivation and field management. Several forecasting models for pesticide application to control EB were created in the last century and more recent scientific advances have included modern breeding technology to detect resistant genes and precision agriculture with hyperspectral sensors to pinpoint damage locations on plants. This paper presents an overview of the EB disease and provides an evaluation of recent scientific advances to control the disease. First of all, we describe the outline of this disease, encompassing biological cycles of the Alternaria genus, favorite climate and soil conditions as well as resistant plant species. Second, versatile management practices to minimize the effect of this pathogen at field level are discussed, covering their limitations and pitfalls. A better understanding of the underlying factors of this disease and the potential of novel research can contribute to implementing integrated pest management systems for an ecofriendly farming system. © 2021 The Authors.

Stemphylium leaf spot can result in significant losses to spinach seed, processing, and fresh market crops. Stemphylium isolates (n = 1,775) collected from 2000 to 2022 from spinach seed, leaves, and seed crop stem residues were used to assess the diversity of species associated with spinach. Eleven Stemphylium species were identified based on cmdA sequences: S. vesicarium (63.6% of isolates), S. beticola (48.9%), S. amaranthi (5.1%), S. eturmiunum (4.5%), S. astragali (4.0%), S. simmonsii (3.4%), and S. lucomagnoense, S. drummondii, S. gracilariae, S. lycopersici, and S. chrysanthemicola (each 0.6 to 1.7%). Only isolates of S. beticola, S. drummondii, and S. vesicarium were pathogenic to spinach. The incidence of spinach seed on which Stemphylium was observed ranged from 2.5 to 73.5% per seed lot, with S. vesicarium and S. beticola predominant. However, only 60.7 and 62.3% of isolates tested for these two species were pathogenic to spinach, respectively. Therefore, the incidence of Stemphylium species on spinach seed may not reflect accurately the risk of a seed lot carrying pathogenic isolates. Fused MAT1-1 and MAT1-2 genes were detected in isolates of S. vesicarium, but only MAT1-1 was detected in S. beticola isolates, which corroborates previous studies that have proposed the two species to be self-fertile. The duration of ascospore dispersal of S. beticola and S. vesicarium from spinach seed crop stem residues in western Washington, the primary region of spinach seed production in the USA, occurred from mid-winter to late spring or early fall, potentially serving as inoculum for the next season’s spinach seed crops. Growers should incorporate residues into the soil after harvest to reduce inoculum production of these pathogens on spinach seed crop residues.
