This invention discloses a method for preparing and applying a coumaric acid-modified MOF nanopesticide loaded with chlorantraniliprole, belonging to the field of pesticide formulation technology. The nanopesticide comprises: an iron-based metal-organic framework carrier MIL-101(Fe); chlorantraniliprole loaded within the pores of the carrier; and coumaric acid modified on the surface of the carrier through electrostatic interactions. The preparation method includes three steps: MIL-101(Fe) carrier synthesis, chlorantraniliprole loading, and coumaric acid surface modification. The process is simple and the conditions are mild. This invention utilizes the alkaline environment of the fall armyworm's gut to trigger carrier degradation, achieving targeted and controlled release of active molecules. Simultaneously, the released MIL-101(Fe) is reduced under the action of GSH in the gut, generating reactive oxygen species through the Fenton reaction, forming a synergistic insecticidal effect with coumaric acid. Experiments have shown that this nanopesticide exhibits far superior insecticidal activity against fall armyworm compared to single agents or carriers, possessing excellent insecticidal activity and environmental compatibility, making it suitable for green agricultural production.

The present application relates to a kind of arylamino-containing xanthine derivatives and its preparation method and application.On the basis of 1,3-disubstituted xanthine raw material, arylamino-containing xanthine derivatives obtained by series of reactions are shown as general formula I.Compounds of general formula I have higher herbicidal activity, and have obvious activity on rape, amaranthus retroflexus, barnyard grass, crabgrass, have good insecticidal activity, especially on the effect of diamondback moth is remarkable, have good fungicidal activity, and have obvious in vitro inhibitory activity on wheat scab fungus, pepper phytophthora blight fungus, sclerotinia sclerotiorum, cucumber fusarium wilt fungus, apple phialophora quercina, wheat sharp eyespot fungus, etc.Compounds of general formula I can be used as active components of herbicidal or insecticidal or fungicidal composition, for preparing agricultural herbicide or insecticide or fungicide, and can be used for the prevention and treatment of grass damage or insect damage or pathogenic damage on various crops.Also have good inhibitory effect on the activity of KARI, and can be used for KARI inhibitor.
