Abstract

The health and productivity of citrus are generally jeopardized by a host of diseases, for which the environmental conditions of the cropping system are critical drivers. Several studies conducted on various diseases of perennial crops have shown the involvement of the structural futures of the cocoa-based agroforestry system (CBAFS) in the spread of pathogens and the epidemics development. This chapter highlights the effect of the CBAFS’s structural characteristics on the intensity of three citrus diseases in the humid forest zones of Cameroon. The involvement of CBAFS structural characteristics in diseases regulation is demonstrated. In particular, the spatial structure of citrus in agroforests shows an effect on the spread of diseases. Moreover, distribution of citrus in the CBAFS, with minimum spacing of 12 m between citrus trees, limits the damage caused by Pseudocercospora leaf and fruit spot disease (PLFSD) and citrus diseases caused by Phytophthora (CDP). Dense shading helps to minimize the intensity of diseases such as CDP and PLFSD and Citrus scab disease. This work may make it possible to contribute to the development of an integrated management tool for citrus diseases in an associated crop context.
优化可可基农林业结构特征的柑橘真菌病害综合治理方法
柑橘的健康和生产力普遍受到多种病害的危害,其中种植系统的环境条件是关键驱动因素。对多年生作物各种病害进行的若干研究表明,以可可为基础的农林复合系统(CBAFS)的结构未来参与了病原体的传播和流行病的发展。本章重点介绍了cafs的结构特征对喀麦隆潮湿林区三种柑橘病害强度的影响。证实了CBAFS结构特征在疾病调控中的作用。尤其是农林复合林中柑橘的空间结构对病害的传播有一定的影响。此外,柑橘在CBAFS内的分布,柑橘树与树之间的最小间距为12 m,限制了Pseudocercospora leaf and fruit spot disease (PLFSD)和Phytophthora (CDP)引起的柑橘疾病的危害。浓密的遮荫有助于减少CDP和PLFSD以及柑橘痂病等疾病的强度。这项工作可能有助于在相关作物环境下开发柑橘病害综合管理工具。
