Abstract

Downy mildew of crucifers is a polycyclic disease under natural conditions. The pathogen requires certain specific nutrients which are produced or become available during pathogenesis to proliferate and continue in life cycle. The disease cycle involves the changes in the plant and the plant symptoms as well as those in the pathogen and spans periods within a growing season and from one growing season to the next. The main events in a disease cycle include inoculation (landing of pathogen propagules on the plant in the nature or otherwise), penetration, infection, growth and reproduction of the pathogen, dissemination of the pathogen, and overwintering or oversummering of the pathogen. The disease cycle has been explained in Section 1 (General Disease Cycle on Cruciferous Crops) and Section 2 (Specific Disease Cycle on Arabidopsis).
