Abstract: Maize is the largest grain crop in China and plays an important role in ensuring food security. However, maize is easily infected by diseases during its growth, among which fungal diseases are widely distributed, spread quickly and do great harm; which has a great impact on the yield and quality of maize. In order to provide reference for the research on the prevention and control of maize fungal diseases and ecological control, the research progress on the inhibition of maize fungal diseases by conservation tillage was reviewed in terms of "cry for help", "response" and "resistance". Current studies showed that under conservation tillage, soil microecology can produce signals to respond to maize fungal infection, and then trigger active disease resistance of maize. In this process, conservation tillage can promote the enrichment of beneficial microorganisms in the rhizosphere, increase the content of mineral elements in the soil, inhibit the occurrence of fungal diseases, and promote the growth and disease resistance of maize. Future research issues on the inhibition of maize fungal diseases under conservation tillage are proposed.
