人类活动正在改变大气中的温室气体浓度，并导致全球气候变化。在不久的将来，巴西的植物检疫情景肯定会因全球气候变化而发生变化。气候变化的影响可以是积极的、消极的或中性的，因为这些变化可以减少、增加或对疾病没有影响，具体取决于每个区域或时期。这些影响还将对植物和其他生物以及其他农业生态系统组成部分进行观察。然而，这些影响并不容易确定，因此，来自几个领域的专家必须超越他们的学科界限，将气候变化的影响置于更广泛的背景下。本文重点讨论了气候变化对植物病害影响的不同方面。关于疾病的地理和时间分布，介绍了历史背景，并讨论了利用与疾病模拟模型相关的未来气候预测模型数据的最新研究，以预测未来气候情景中的分布。显示了巴西一些作物未来的预测疾病情景。在大气CO2和其他气体浓度增加的影响方面，讨论了未来在大气气体条件改变下疾病如何变化的重要方面。还讨论了这些变化对植物病害的化学和生物防治的影响。
Human activities are altering greenhouse gas concentrations in the atmosphere and causing global climate change. In the near future, there will certainly be changes in the Brazilian phytosanitary scenario attributed to global climate change. The impacts of climate change can be positive, negative or neutral, since these changes can decrease, increase or have no impact on diseases, depending on each region or period. These impacts will also be observed on plants and other organisms as well as on other agroecosystem components. However, these impacts are not easily determined, and consequently, specialists from several areas must go beyond their disciplinary boundaries and placing the climate change impacts in a broader context. This review focuses on the discussion of different aspects related to the effects of climate change on plant diseases. On the geographical and temporal distribution of diseases, a historical context is presented and recent studies using data of forecast models of future climate associated with disease simulation models are discussed in order to predict the distribution in future climate scenarios. Predicted future disease scenarios for some crops in Brazil are shown. On the effects of increasing concentrations of atmospheric CO2 and other gases, important aspects are discussed of how diseases change under altered atmospheric gases conditions in the future. The consequences of these changes on the chemical and biological control of plant diseases are also discussed.
