Impact of Climate Change on Plant Diseases and IPM Strategies

Abstract

There has been a remarkable scientific output on the topic of how climate change is likely to affect plant diseases. Climate change influences the occurrence, prevalence, and severity of plant diseases. Projected atmospheric and climate change will thus affect the interaction between crops and pathogens in multiple ways. This will also affect disease management with regard to timing, preference, and efficacy of chemical, physical, and biological measures of control and their utilization within integrated pest management (IPM) strategies. Prediction of future requirements in disease management is of great interest for agro-industries, extension services, and practical farmers. A comprehensive analysis of potential climate change effects on disease control is difficult because current knowledge is limited and fragmented and due to the complexity of future risks for plant disease management, particularly if new crops are introduced in an area. Uncertainty in models of plant disease development under climate change calls for a diversity of management strategies, from more participatory approaches to interdisciplinary science. Involvement of stakeholders and scientists from outside plant pathology shows the importance of trade-offs. All these efforts and integrations will produce effective crop protection strategies using novel technologies as appropriate tools to adapt to altered climatic conditions.

Mitigation of emerging implications of climate change on food production systems

“…For example, impacts on pollinators (Kehrberger & Holzschuh, 2019), such as bees, are already under great pressure from habitat loss and intensive agriculture. The same is about the effects of global warming on pests and diseases in crops (Zayan, 2019) or livestock (Kebede et al, 2018).…”

“…The impact of climate change on increases in plant pests is also of global concern because a lot of resources are required to control this problem. Zayan [ 76 ] indicated that in the US alone, farmers spent more than USD 11 billion for pest control. Additionally, they reported that global climate change could cause some plant pests to undergo from one to five additional lifecycles per season, increasing their ability to overcome plant pest resistance.…”

The dynamic of pests and plant diseases during three consecutive rice growing seasons

“…After the introduction of the green revolution in Indonesia, rice pests and diseases outbreak became more frequent. In addition, changes in climatic factors such as temperature, rainfall and humidity highly affect crop production and insect population as well as pest-disease infestation [5].…”
