Forest Diseases

Pathogens and insect pests are important drivers of tree mortality and forest dynamics, but global change has rapidly altered or intensified their impacts. Predictive understanding of changing disease and outbreak occurrence has been limited by two factors: ( a) tree mortality and morbidity are emergent phenomena determined by interactions between plant hosts, biotic agents (insects or pathogens), and the environment; and ( b) disparate global change drivers co-occur, obscuring net impacts on each of these components. To expand our understanding of changing forest diseases, declines, and outbreaks, we adopt a framework that identifies and organizes observed impacts of diverse global change drivers on the primary mechanisms underlying agent virulence and host susceptibility. We then discuss insights from ecological theory that may advance prediction of forest epidemics and outbreaks. This approach highlights key drivers of changing pest and pathogen dynamics, which may inform forest management aimed at mitigating accelerating rates of tree mortality globally.

And Control

Based on the characteristics and current situation of crop diseases and insect pests, this paper analyzes the problems of farmers’ lack of awareness of prevention and control, blind introduction of quarantine pests that lead to the spread of quarantine pests, and lack of advanced pest control technology in the prevention and control of crop diseases and pests. , For reference and reference.

Forest Diseases

The pine tree is an important tree species in China. In recent years, in order to quickly obtain a lot of woods and higher economic benefits, a large area of artificial pine forests is created in different places, coupled with the productivity decline of our country’s artificial pine forests and the formation of fragile forest ecosystems, which lead to serious plant diseases and insect pests. Some quarantine diseases spread quickly, causing huge losses to the production of artificial pine forests. This paper provides an overview of pathogennies, symptoms, occurrence situations of three important quarantine diseases of artificial pine forests occurring in Hunan province, and proposes control measures, which provide references for taking further effective measures to control artificial pine forest diseases.
