Research Progress of Engineered Nanomaterials against Crop Diseases
Nanotechnology is expected to alleviate the food crisis caused by population growth to a certain extent,and the slow-release,high-efficiency and low-dose properties of nano-scale agrochemicals(e.g.nano-fertilizers and nano-pesti-cides)reduce negative environmental impacts caused by traditional agricultural chemicals.This review article focuses on the intrinsic mechanisms of engineered nanomaterials(ENMs)to control crop diseases through direct and indirect path-ways.The article focuses on ENMs to resist oxidative stress caused by pathogen invasion in plants by regulating plant nutri-tion,inducing antioxidant enzyme activity and improving plant photosynthesis.In addition,it is also demonstrated that ENMs induced plant systematic acquired resistance(SAR)to enhance their disease resistance.In conclusion,an in-depth exploration of the disease resistance mechanism of ENMs can effectively improve plant disease management,achieve an in-crease in crop yield and quality,and greatly reduce the negative impact of traditional agrochemicals on the agro-ecological environment.
