AbstractThe microbial control，botanical pesticide management，andtheirsynergistic control strategies with chemicalagentsfor northerncorn leafblightweresystematicallelaborated.Intermsof microbialcontrol，biocontrol fungi（such as Trichoderma and Clonostachys），bacteria （such as Bacillusand Paenibacillus），andactinomycetes were demonstrated to function through multiple mechanisms，including antagonism，mycoparasitism，secretionof antimicrobial substances，and inductionof plantresistance.Botanical pesticides （e.g.，extracts from Sophora flavescens and Mikania micrantha）and plant immune regulators （e.g.，alginate oligosaccharides）were shown to directlyinhibit pathogens and activate the plant’sown defense system，ofering both diseasecontrol and growth-promoting effects.In termsofsynergisticcontrolstrategies，thescientificcombinationof biocontrolagents （suchas TrichodermaandBacilus amyloliquefaciens）with selective chemical pesticides was found to form a complementary control system.This approach not onlyenhanced control efcacy but also effctively reduced the input ofchemical pesticides.Future research should promote the large-scale application of related control technologies through precise screening，optimization of synergistic strategies，and integrationofcomprehensive techniques.This article providesareference for the preventionand control

of maize diseases and pests.
