由葡萄孢属物种的成员引发的疾病取决于一系列复杂的生物事件，包括宿主和环境感知、真菌繁殖体与宿主表面之间的化学和物理相互作用以及宿主表面上的微生物相互作用。病原体的接种物是理解这种相互作用的核心。本章介绍了接种生态的葡萄孢属植物表面的物种，并将此信息的理解疾病的启动。葡萄孢属物种部署几个繁殖体和生存结构。这些繁殖体的精确行为的知识，特别是疏水分生孢子，当分散和沉积在主机上在高相对湿度的存在或不存在的水滴是重要的疾病的启动和控制。繁殖体对环境的反应，以及这些病原体在攻击策略中所表现出的多样性进行了讨论，并举例说明了所使用的感染途径。对灰霉病病的适宜接种方法进行了评述。
The initiation of disease by members of Botrytis species depends on a complex sequence of biological events involving host and environment sensing, chemical and physical interactions between the fungal propagules and the host surface and the microbial interactions on the surface of the host. The pathogen's inoculum is central to the understanding of this interaction. This chapter describes the inoculum ecology of Botrytis species on plant surfaces and relates this information to an understanding of disease initiation. Botrytis species deploy several propagules and survival structures. A knowledge of the precise behaviour of these propagules, especially the hydrophobic conidia, when dispersed and deposited on the host at high relative humidity in the presence or absence of water droplets is important for disease initiation and control. The responsiveness of propagules to the environment, and the diversity shown in attack strategies by these pathogens are discussed with examples of the infection pathways used. Special comment is made about suitable inoculation procedures to study grey mould in leaves and fruits.
