Last Updated: 2024/11/05, How is wheat downy mildew transmitted? Wheat downy mildew is a fungal disease. The pathogen oversummered in the host diseased tissue with oospores. The oospores germinate and produce sporangia when the conditions are suitable. Oospores and sporangia spread by running water, germinate and produce zoospores, which invade from coleoptile to hyphae, and hyphae penetrate into host larvae.

The oospores germinate and produce sporangia when the conditions are suitable. Oospores and sporangia spread by running water, germinate and produce zoospores, which invade from coleoptile to hyphae, and hyphae go deep into the growth point of host young bacteria for systematic infection. The autumn seedling stage of wheat is the main infection time of the pathogen, and stagnant water in the field or improper irrigation are beneficial to the disease.
