Grazing can control the occurrence of some plant diseases

Spore pile and spore morphology of Potentilla rust

Grazing is the most important way of using grassland.

Plant pathogens can be divided into pathogenic fungi, pathogenic oomycetes, pathogenic bacteria and plant viruses.

The long-term yak grazing intensity experimental platform established by the Zoige Alpine Wetland National Field Science Observation and Research Station of Southwest University for Nationalities provides an ideal research system for exploring how grazing affects plant diseases caused by pathogens of different life history types.

In order to further confirm whether the discovery is universal, the researchers used data integration analysis to find 66 research cases on the effects of grazing on plant diseases worldwide.

"Our work on the one hand incorporates the types of life history into the prediction of plant diseases, which greatly improves our ability to predict the occurrence of natural grassland diseases; on the other hand, it reveals from the phenomenon and mechanism that moderate grazing can also help control The occurrence of some diseases provides an indirect promotion to the health and stability of the grassland.
