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.

交链格孢属是众所周知的侵袭性病原菌，分布广泛，气候变化引起的温度升高可能会使其更大量增加。早疫病（EB）主要由茄链格孢引起，而褐纹病则由交链格孢引起，是马铃薯、番茄和茄子生产中的主要关注点。EB 的发展与品种、作物发育阶段、环境因素、栽培和田间管理密切相关。上世纪已经创建了几个用于防治 EB 的农药应用预测模型，而最近的科学进步则包括现代育种技术来检测抗性基因和精准农业中的高光谱传感器，以精确定位植物上的损伤位置。本文概述了 EB 疾病，并对近年来控制该疾病的科学进展进行了评估。首先，我们描述了这种疾病的概况，包括交链格孢属的生物周期、喜欢的气候和土壤条件以及抗性植物物种。其次，讨论了在田间最大限度减少这种病原体影响的多种管理措施，涵盖了它们的局限性和缺陷。更好地了解这种疾病的潜在因素和新研究的潜力有助于为生态友好型农业系统实施综合虫害管理系统。2021 年作者。害虫管理科学由 John Wiley & Sons Ltd 代表化学工业协会出版。
